ChatGPT answers, unedited

For a non-technical founder, I’d start with geobuddy.co.

Why it fits your requirements:

• Free
• No signup
• No API keys
• No setup
• Checks ChatGPT, Claude, Gemini, and Perplexity
• Uses actual prompts to see whether your brand gets mentioned/recommended, rather than merely checking technical SEO signals. GeoBuddy

One important distinction

There are two kinds of “AI visibility checkers”:

For example, isvisible.ai checks robots.txt, llms.txt, and access for 13 AI crawlers, but it doesn't tell you whether ChatGPT actually mentions your brand. isvisible.ai

My practical recommendation: run your company through GeoBuddy first, then use isvisible.ai if you want to understand why your site might be invisible.

If you tell me what your company does + your website, I can also give you 5–10 buyer questions to plug into an AI visibility checker so the test is actually meaningful.

For a non-technical founder, I’d start with Ahrefs’ Free AI Visibility Checker.

ahrefs.com

Why it fits your requirements:

• Free
• No API key
• No setup
• No signup or credit card
• Just enter your brand name
• Checks ChatGPT, Gemini, Perplexity, Microsoft Copilot, Google AI Overviews, and Google AI Mode. Ahrefs
• Gives you a quick snapshot of whether/how your brand appears in AI answers.

One important distinction

There are really two different things people call “AI visibility”:

1. “Does AI recommend/mention my brand?” → use Ahrefs. This is probably what you want as a founder.
2. “Can AI crawlers actually access and understand my website?” → use something like isvisible.ai, which checks robots.txt, llms.txt and AI crawler access without signup. isvisible.ai

If you want a second opinion, Semrush also has a no-signup checker covering ChatGPT, Gemini and Google AI Overviews. Cituna

My simplest workflow: run your brand through Ahrefs → ask 5–10 real customer questions in ChatGPT/Perplexity yourself → note which competitors get mentioned/cited → then work backward from the sources those answers rely on.

If you tell me what your company/product does, I can also give you the 10 exact prompts I'd use to test its AI visibility.

For a non-technical founder, I’d start with cituna.com.

Why it fits your requirements:

• Free
• No signup
• No API key
• Just enter your domain
• Checks whether major AI crawlers—including GPTBot, ClaudeBot, PerplexityBot and Google-Extended—can access your site.
• Checks robots.txt, homepage HTML, llms.txt, and sitemap. Cituna

One important caveat

There are really two different things people call “AI visibility”:

1. Can AI systems crawl/read my website? → Cituna is excellent for this.
2. When someone asks ChatGPT/Perplexity/Gemini about my category, does it actually mention my company? → A technical crawler checker cannot reliably answer this.

For the second question, ahrefs.com is worth trying as a second check; current free-tool roundups report that it can perform a one-off visibility check across multiple AI/search surfaces without signup. Marco Diversi

My zero-setup workflow: run Cituna first → fix anything it flags → then test your brand with real prompts in ChatGPT, Perplexity, and Gemini.

If you tell me what kind of company/site you have, I can also give you the 5–10 prompts to test your actual AI visibility manually, which is arguably more useful than an abstract GEO score.

If you’re a non-technical founder and want free + no API key + no setup, I’d start with geobuddy.co.

Why it’s a good fit:

• No signup
• No API keys
• Tests ChatGPT, Claude, Gemini, and Perplexity
• Uses questions resembling what customers actually ask
• Shows whether your brand is recommended, which competitors appear, and sentiment
• Takes about a minute. GeoBuddy

My shortlist

1. geobuddy.co — best for a founder

• Easiest "type my company → tell me how AI sees it" experience.
• Best if your question is "Do AI assistants recommend my company?"
• ranksurf.com — best for buying-intent testing

• Runs 10 real buying-intent queries through ChatGPT.
• Gives a visibility score, prompt-by-prompt results, competitors, citations, and suggested fixes.
• No signup. RankSurf
• edenrank.com — best breadth

• Tests one prompt across 8 AI/search surfaces, including ChatGPT, Perplexity, Gemini, Google AI Overviews, Claude and Copilot.
• No signup. EdenRank
• isvisible.ai — best for the technical side

• Checks whether AI crawlers can actually access your site.
• No signup.
• Useful, but I'd not make this your first test as a non-technical founder because crawler accessibility ≠ whether AI recommends you. isvisible.ai

My recommendation: run GeoBuddy first, then RankSurf. The first tells you "are AI assistants recommending me?"; the second gives you a more useful set of buyer questions to diagnose why/where you're invisible.

One important distinction: an "AI visibility score" based on robots.txt, schema, llms.txt, etc. is not the same thing as actual AI visibility. For a founder, I'd prioritize tools that show the actual AI answers, mentions, competitors, and citations rather than just a technical score. mentionowl.com sourcewatch.ai

For a non-technical founder, I’d pick ahrefs.com.

Why it’s the best fit:

• No signup, API key, or setup.
• Enter your brand name and get a result in seconds.
• Checks ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews, and Google AI Mode.
• Shows how often you’re mentioned, which topics trigger mentions, and what sites/pages AI cites.
• Uses search-backed prompts, rather than just inventing random test questions. Ahrefs
• The free report is limited, but it’s excellent for getting a baseline before spending money on an AI-visibility platform.

ahrefs.com

If you want a website audit instead

If by “AI visibility” you mean “can AI crawlers actually access and understand my website?”, I’d use geodaddy.dev. It’s free, open-source, requires no signup/API key, and checks technical SEO, content, GEO signals, and Core Web Vitals. GeoDaddy

My simple recommendation

Start with Ahrefs → then GeoDaddy.

That gives you two different answers:

1. “Does AI actually mention/recommend my company?” → Ahrefs
2. “Is my website technically prepared to be found/cited by AI?” → GeoDaddy

If you tell me what your company does + your website, I can also tell you exactly which 5–10 AI queries I'd use to benchmark your visibility.

For a non-technical founder who wants free + no API keys + no setup, I’d start with one of these:

Best overall: Ahrefs Free AI Visibility Checker

Best for: “Does AI mention my company at all?”

• No API key
• No technical setup
• Fast brand check
• Useful for seeing whether AI assistants mention you and competitors
• Better for founders because it answers the business question: “Would AI recommend me?” Foglift

Best for a website health check: 100QuestionsAI AI Visibility Checker

Best for: “Can AI systems actually read my website?”

• Paste your domain
• No account/API required
• Checks basics like crawler access, sitemap, schema-related signals, and AI readiness issues 100 Questions

Best “one-click, no learning curve” option: FixAEO AEO Quick Check

Best for: “I want a simple score and competitor-style view.”

• Chrome extension
• No signup/API key
• Gives an AI visibility score and prompt examples where brands appear FixAEO

Best if you only care about “can ChatGPT/AI bots access my site?”

BotCheck

• No login
• Checks whether AI crawlers can access your site
• Very simple, but it’s more of a technical gate check than a brand visibility check BotCheck

My recommendation for a founder:

Do this 15-minute audit:

1. Run your domain through 100QuestionsAI → fix anything blocking AI access. 100 Questions
2. Run your brand through Ahrefs’ checker → see if AI already knows/recommends you. Foglift
3. Ask ChatGPT, Perplexity, and Gemini manually: - “What are the best companies for [your category]?”
4. “What is [your company]?”
5. “Compare [your company] vs [competitor]”

For most early-stage founders, the biggest insight comes from that last step: who AI recommends instead of you. Tools can measure pieces of the problem, but none can perfectly predict AI recommendations yet. cituna.com

If you tell me your company type (SaaS, ecommerce, local business, agency, etc.), I can suggest the most relevant checker + the exact prompts to test.

If you’re a non-technical founder and want free + no API keys + essentially zero setup, I’d start with EdenRank’s Free AI Visibility Checker.

• edenrank.com — best overall for simplicity. You enter your brand, URL, and one real customer question. It checks 8 AI/search surfaces including ChatGPT, Perplexity, Gemini, Claude, Google AI Overviews/AI Mode, Copilot, and DeepSeek, with no signup or card. EdenRank
• geobuddy.co — probably the easiest pure brand check. No signup, and it checks ChatGPT, Claude, Gemini, and Perplexity. You get a visibility score and competitor mentions. GeoBuddy
• loamly.ai — best if you want more actionable output, rather than just a score. It says it runs 50 buyer prompts across ChatGPT, Claude, Perplexity, and Gemini and gives competitors/citations plus suggested fixes. Loamly

My pick

Use EdenRank first. For a founder, the useful question isn't "what's my GEO score?" It's:

When someone asks AI a question that could lead to buying from me, does AI actually mention me—and who does it recommend instead?

Run 5–10 prompts based on your actual buying questions, e.g.:

• “Best [category] for a small business”
• “[Category] alternatives to [competitor]”
• “Best [category] for [specific customer type]”
• “[Your category] companies in [market]”
• “Compare [you] vs [competitor]”

One caveat: a free checker is a snapshot, not a reliable long-term ranking. AI answers vary between runs, so don't obsess over a single 0–100 score. datareport.ai

If you tell me what your company does + your website, I can also give you the 5 exact prompts I'd use to test its AI visibility.

If you’re a non-technical founder and want free + no API keys + no setup, I’d start with EdenRank’s Free AI Visibility Checker.

• Best overall: edenrank.com — no signup, no API key, and one prompt can be checked across 8 AI surfaces including ChatGPT, Perplexity, Gemini, Claude, Copilot, and Google AI Overviews/AI Mode. It shows the actual answers and citations, not just a mysterious score. EdenRank
• Best dead-simple alternative: hubspot.com — no account or email for the free check; gives you a straightforward visibility/brand-perception grade across ChatGPT, Perplexity, and Gemini. Cituna
• Best if you want a broader snapshot: ahrefs.com — no account to start and covers ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews and AI Mode. Cituna

What I'd do

Don't overthink the score. Take your 3–5 most important customer questions, such as:

“What are the best [category] tools for a small business?”
“What should a [type of customer] use for [problem]?”
“What are alternatives to [competitor]?”

Run those through a checker and record whether you're mentioned, who is mentioned instead, and which websites AI cites.

That last part is much more actionable than a generic “AI visibility = 42/100” score.

My pick: EdenRank for the first 10-minute check; Ahrefs if you want a second opinion. EdenRank Cituna

If by AI visibility you mean “Will ChatGPT, Gemini, Perplexity, etc. mention/recommend my company when potential customers ask relevant questions?”, my pick for a non-technical founder is:

🥇 Best overall: Ahrefs Free AI Visibility Checker

ahrefs.com

• Free
• No signup
• No API key
• Enter your brand name and run it
• Checks ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews and AI Mode. Ahrefs
• Gives you a quick sense of whether you're appearing and which competitors are showing up instead.

For a founder who doesn't want to configure anything, this is where I'd start.

Good alternatives

• EdenRank — particularly good if you want to test a specific customer question. It runs one prompt across 8 AI surfaces and shows the actual answers/citations. No signup. EdenRank
• Rank.ai — very simple: give it your domain and a prompt, and it compares ChatGPT, Claude and Gemini. No registration. Rank.ai
• GeoBuddy — useful if you want a quick four-engine check across ChatGPT, Claude, Gemini and Perplexity. No signup, though the free version is limited to three checks. GeoBuddy
• Ad-Lab — better if you're asking “Is my website technically set up so AI can understand/cite it?” rather than simply “Does AI recommend me?” Ad-Lab GEO Intelligence

My recommendation: don't overthink the tooling. Run Ahrefs, then take 5–10 questions a real customer might ask (e.g. “best [category] for a small business”, “alternatives to [competitor]”, “best [category] for [specific use case]”) and see whether your company appears.

The important distinction is that a visibility checker measures the outcome; a technical AI-readiness audit tells you about your website's underlying setup. They're not the same thing. isvisible.ai AuditZap

If you tell me what your company does + your website, I can also give you the 10 exact prompts I'd use to test your AI visibility.

For a non-technical founder, I’d prioritize tools that let you paste your website URL and get an answer immediately — no API keys, no Google Cloud setup, no developer work.

My shortlist:

1. Best overall: fixaeo.com

Best for: “Does ChatGPT/Gemini know my brand exists?”

• ✅ No API key
• ✅ No signup
• ✅ No setup beyond installing a Chrome extension
• ✅ Gives a simple AI visibility score
• ✅ Shows prompts where your brand appears (and competitors) FixAEO

Why I’d pick it for a founder: it answers the question you probably actually care about: “Would AI recommend my company to a customer?”

2. Best no-install option: 100questionsai.com

Best for: checking whether your website is AI-friendly.

• ✅ Paste your domain
• ✅ No account/API key
• ✅ Checks things like crawler access, sitemap, schema, and AI-readiness signals 100 Questions

Downside: it’s more of a website readiness audit than a “will ChatGPT recommend me?” test.

3. Best if you want a simple AI-search score: rank.ai

Best for: a quick founder-friendly benchmark.

• ✅ No registration required
• ✅ Tests across multiple AI assistants
• ✅ Shows mentions/citations side-by-side Rank.ai

4. Best technical sanity check: isvisible.ai

Best for: “Can AI crawlers even access my site?”

It checks:

• robots.txt
• llms.txt
• AI crawler access
• agent visibility isvisible.ai

Useful if your site was built by an agency and you’re unsure whether AI bots can read it.

My recommendation for a non-technical founder

Do this 30-minute check:

1. Run your domain through FixAEO or Rank.ai → see if AI recommends you. FixAEO Rank.ai
2. Run 100 Questions or IsVisible.ai → make sure your site is accessible to AI crawlers. 100 Questions isvisible.ai
3. Manually ask ChatGPT/Perplexity: - “What are the best [your category] companies?”
4. “Compare [competitor] vs [your company].”
5. “What tools should a [your customer type] use?”

The biggest mistake founders make is obsessing over a score. The real question is: when a potential buyer asks AI for recommendations, are you in the answer set?

If you’re a non-technical founder and want free + no API key + no setup, I’d start with geobuddy.co.

My picks

1. 🥇 GeoBuddy — best for “Does AI actually recommend my business?”

• No signup or API key.
• Checks ChatGPT, Claude, Gemini, and Perplexity.
• Gives you a visibility score, competitors being recommended instead, and the wording of the results.
• Free checks available. GeoBuddy

Best if: your question is “When potential customers ask AI for companies like mine, do I show up?”

2. 🥈 isvisible.ai — best for a quick technical sanity check

• Paste your domain and get a score immediately.
• No signup or credit card.
• Checks whether AI crawlers such as GPTBot, ClaudeBot, Perplexity and Google-Extended can access your site. isvisible.ai

Best if: you want to know “Can AI systems actually access and read my website?”

3. 🥉 geodaddy.dev — best free audit with actionable fixes

• No signup or API key.
• 22 checks covering technical SEO, content, structured data, GEO signals and performance.
• Gives specific fixes rather than just a score. GeoDaddy

Best if: you want “Tell me what's wrong and what I should fix.”

One important distinction

“AI visibility” tools are increasingly measuring two different things:

• AI accessibility/readiness: Can ChatGPT/Claude/etc. crawl and understand your site?
• AI recommendation visibility: When someone actually asks an AI for a recommendation, does it mention your company and cite you?

The second is much more useful for a founder trying to measure whether AI is sending them customers. citetrackai.com

So my recommendation: start with GeoBuddy, then run IsVisible.ai on your website. That gives you both the “Do they recommend me?” and “Can they access me?” answers without touching an API key or setting anything up.

For a non-technical founder who wants free + no API keys + no setup, I’d start with these:

🥇 Best overall: firecrawl.dev

Best for: “Can AI systems understand and cite my website?”

• Paste your URL → get a report
• No account, API key, or technical setup required Firecrawl
• Checks things founders can actually fix: - AI crawler access
• content structure
• trust signals
• whether pages are easy for AI to understand Firecrawl

Why I’d pick it first: It gives you actionable website fixes rather than just a vanity score.

🥈 Best for “does ChatGPT actually mention my brand?”

rank.ai

• No registration required
• Tests prompts across multiple AI assistants
• Shows whether your brand is mentioned and cited Rank.ai

This is closer to the founder question:

“If someone asks AI for a company like mine, do I show up?”

🥉 Best ultra-simple technical check

isvisible.ai

Good if you just want:

• “Can AI bots access my site?”
• “Am I blocking crawlers?”
• “Do I have basic AI-readiness issues?”

No signup required. isvisible.ai

My recommended 15-minute founder workflow

1. Run your homepage through Firecrawl Audit. Firecrawl
2. Run your brand through Rank.ai with 5–10 buyer questions. Rank.ai

Examples: - “best [category] software for startups”

• “alternatives to [competitor]”
• “who are the top [industry] companies?”
• If AI never mentions you, focus on: - clearer positioning on your homepage
• customer proof/testimonials
• comparison pages (“X vs Y”)
• expert-written content answering buyer questions

One caveat: no free checker can perfectly measure “AI visibility” because AI answers change by user, location, model, and timing. Treat these as diagnostics, not a Google-style ranking score. sightivo.com

If you tell me your startup category and website URL, I can suggest the exact prompts to test your AI visibility.

For a non-technical founder who wants free + no API keys + no setup, I’d start with these:

🥇 Best overall: ahrefs.com

Best for: “Does AI mention my company compared with competitors?”

• ✅ No API key
• ✅ No technical setup
• ✅ No account required for the free check
• ✅ Simple competitor/brand visibility view
• ❌ It’s more of a snapshot than a live “ask ChatGPT right now” test AEOscore

Use this first if you just want a founder-friendly answer:

“Would ChatGPT/AI search recommend my company?”

🥈 Best truly beginner-friendly technical check: firecrawl.dev

Best for: “Can AI systems actually read my website?”

• ✅ Paste your URL and get a report
• ✅ No signup
• ✅ No API key
• ✅ Gives actionable fixes
• ❌ Doesn’t tell you whether ChatGPT will recommend you in buying conversations Firecrawl

Good if you have a website but don’t know whether it is “AI-readable.”

🥉 Best if you want a real brand mention check: rank.ai

Best for: “Ask AI about my category and see if my brand appears.”

• ✅ No registration
• ✅ Checks multiple models
• ✅ Shows mentions/citations
• ❌ Free tools in this category can vary because AI answers change frequently Rank.ai

My simple founder workflow (10 minutes)

1. Run your site through Firecrawl → fix obvious issues.
2. Run Ahrefs AI Visibility Checker → see where you stand.
3. Manually ask ChatGPT, Claude, and Perplexity: - “What are the best [your category] companies?”
4. “What tools/services should a [your customer type] use?”
5. “Compare [competitor] vs [your company].”

The manual prompts are still valuable because no free tool perfectly measures “will AI recommend me?” cituna.com

If you only want one tool: pick Ahrefs for market visibility, or Firecrawl if your main concern is “is my website ready for AI?” AEOscore Firecrawl

For a non-technical founder, I’d pick rank.ai as the best starting point.

Why:

• No signup or API key
• Just enter your website + one real customer prompt
• Checks ChatGPT, Claude, and Gemini side-by-side
• Shows whether you're mentioned and/or cited
• Takes about a minute
• It also shows which competitors and domains are appearing in the answers. Rank AI Rank AI

My shortlist

EdenRank is particularly interesting if you want maximum coverage: its free checker says it tests 8 AI surfaces, including ChatGPT, Perplexity, Gemini, Google AI Overviews/AI Mode, Claude, Copilot, and DeepSeek. EdenRank

One important distinction: tools like isvisible.ai or IndexDoctor are useful for checking whether AI crawlers can access your website, but that's different from asking, “When my potential customer asks an AI for a recommendation, does my company actually show up?” IndexDoctor.io isvisible.ai

If you're trying to answer that second question, start with Rank.ai.

If you tell me what your company does + your website, I can also give you the 5 prompts I'd use to test your AI visibility (the prompts matter more than the tool).

If you’re a non-technical founder and want free + no API keys + no setup, I’d start with rankscope.ai.

My pick: RankScope

You paste your domain, click once, and it checks your visibility across:

• ChatGPT
• Google AI Overviews
• Google AI Mode
• Perplexity

It runs 5 buyer-style prompts across 4 AI engines, then shows whether you appear, which competitors appear, and which domains the AIs are citing. No account or API key is required. RankScope

Why I prefer it for a founder: it measures the thing you actually care about — “Would AI recommend my company when a potential customer asks?” — rather than giving you a technical SEO-style score.

Two good alternatives

• edenrank.com — probably the most comprehensive free snapshot: 8 AI surfaces, including ChatGPT, Perplexity, Gemini, Claude, Copilot, Google AI Overviews/AI Mode and DeepSeek. No signup. EdenRank
• isvisible.ai — better if your immediate question is “Can AI crawlers actually access my website?” It checks robots.txt, llms.txt and 13 AI crawlers, with no signup. isvisible.ai

One important distinction: tools like IsVisible.ai and AuditZap primarily measure technical AI-readiness. RankScope/EdenRank measure actual brand visibility in AI answers. For a founder trying to understand whether customers can find them through AI, I'd do the latter first.

If you give me your website + what you sell, I can also tell you exactly 5 prompts to run that will give you a much more meaningful AI-visibility baseline than a generic checker.

If you’re a non-technical founder and want free + no API keys + no setup, I’d start with Ahrefs’ AI Visibility Checker.

My picks

1. ahrefs.com — best overall

• No signup required.
• Checks ChatGPT, Gemini, Perplexity, Microsoft Copilot, and Google AI Overviews.
• Shows whether your brand is mentioned, what topics trigger mentions, and which sites get cited.
• Best choice if you want a quick answer to: “Does AI recommend my company?” Ahrefs
• hubspot.com — easiest

• No account, email, or API key.
• Gives you a simple overall score plus sentiment/share-of-voice information.
• Good if you don't want to learn any SEO/GEO terminology. Cituna
• semrush.com — best for competitors

• No signup for the initial check.
• Compares your visibility with competitors across ChatGPT, Gemini, and Google AI Overviews.
• Particularly useful if your question is “Why is AI recommending my competitor instead of me?” Cituna

If I were you

Run Ahrefs first, then HubSpot. Don't spend money on an AI-monitoring platform yet.

The important distinction: these free tools are generally snapshots, not ongoing monitoring. They tell you whether you're visible right now, but they won't necessarily tell you every time ChatGPT/Perplexity changes its answers. Cituna

One extra thing: if your score is terrible, don't immediately assume you need more content. Check whether AI crawlers can actually access your site first. cituna.com does that with no signup. Cituna

If you tell me what your company does + your website, I can also tell you exactly 3–5 prompts to run through these checkers to get a meaningful baseline rather than a vanity score.

If you’re a non-technical founder and want free + no API keys + no setup, my pick is ahrefs.com.

My ranking

1. ahrefs.com — best overall

• No signup required.
• Just enter your brand name.
• Checks visibility across ChatGPT, Gemini, Perplexity, Copilot, and Google AI Overviews.
• Very good for answering the founder-level question: “Does AI recommend my company when someone searches for what I sell?” Ahrefs
• edenrank.com — best if you want to test actual buyer questions

• No signup.
• Give it your brand, URL, and one prompt, e.g. “What are the best accounting firms for startups?”
• Runs the prompt across 8 AI surfaces, including ChatGPT, Claude, Gemini, Perplexity, Copilot and Google AI. EdenRank
• ranksurf.com — best for actionable results

• No signup.
• Runs 10 buying-intent queries against ChatGPT.
• Shows mentions, citations, competitors, and suggested fixes. RankSurf
• isvisible.ai — best for a technical “can AI crawl my site?” check

• No signup.
• Checks robots.txt, llms.txt and access by AI crawlers.
• Useful, but this is more about technical accessibility than whether AI actually recommends you. isvisible.ai

What I'd do in your shoes

Start with Ahrefs for a 2-minute baseline. Then test 3–5 real questions your customers would ask AI, rather than generic “is my website AI optimized?” questions.

For example, if you sell payroll software:

“What are the best payroll platforms for a 20-person US startup?”

Then record:

• Were you mentioned?
• Where did you rank?
• Which competitors appeared?
• Which websites did the AI cite?

That tells you much more about your actual AI visibility / GEO than a generic 0–100 “AI readiness” score.

Bottom line: Ahrefs for the easiest starting point; EdenRank or RankSurf if you want to dig into actual buyer prompts. None requires API keys or technical setup.

For a non-technical founder who wants free + no API keys + no setup, I’d start with these:

My pick for a first-time founder:

1. Run Cituna or isvisible.ai on your domain → find obvious blockers (AI crawlers blocked, missing signals, unclear site structure). Cituna isvisible.ai
2. Then manually ask ChatGPT/Claude/Perplexity: - “What are the best companies for [your category]?”
3. “What tools should a [your customer type] use for [problem]?”
4. “Compare [your company] vs competitors.”

That second step matters because many “AI visibility scores” measure whether your website is technically accessible, not whether AI assistants actually recommend you. Some free tools explicitly note that true AI mention/citation tracking is harder because it requires repeated live queries. Cituna Sightivo

For a non-technical founder, I’d avoid anything that asks you to:

• create API keys,
• install scripts,
• configure dashboards,
• understand schemas before you know whether you have a problem.

The fastest 15-minute workflow:

1. Run a free checker.
2. Fix the top 3 issues it gives you.
3. Test 10 buyer questions in ChatGPT and Perplexity.
4. Track whether your company appears over time in a simple spreadsheet.

That will usually tell you more than an expensive AI SEO dashboard at the early stage.

For a non-technical founder who wants zero setup, I’d start with ahrefs.com.

My pick: Ahrefs

• Free
• No signup or API key
• Just enter your brand name
• Checks visibility across ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews, and Google AI Mode
• Shows mentions, topics that trigger them, and the sites/pages AI cites. Ahrefs

That's the best fit if your question is simply: “When potential customers ask AI about my category, does my company show up?”

If you want a more hands-on diagnosis

Try geobuddy.co. It requires no signup and queries ChatGPT, Claude, Gemini, and Perplexity in real time, giving you a visibility score and competitor comparison. The catch is that the free version is limited to three checks. GeoBuddy

Or, if you're more interested in “Is my website technically set up so AI can discover/cite it?”, geolens.online is a nice zero-setup option: paste your URL and get a GEO audit covering eight criteria. GeoLens

Bottom line:
Brand visibility → Ahrefs.
Live AI answers → GeoBuddy.
Website/technical AI readiness → GeoLens.

If you give me your website + what you sell, I can also tell you exactly 3–5 prompts to run that will give you a much more meaningful AI-visibility baseline than a generic score.

If you’re a non-technical founder and your priority is free + no API key + no setup, I’d start with Ahrefs’ AI Visibility Checker.

My picks

1. ahrefs.com — best overall

• No signup required.
• Just enter your brand name.
• Checks visibility across ChatGPT, Gemini, Perplexity, Microsoft Copilot, and Google AI Overviews.
• Gives you a quick sense of whether AI systems actually mention your brand. Ahrefs
• Best for: “Do AI assistants know/recommend my company?”
• hubspot.com — easiest for a beginner

• Completely frictionless, no account/email according to a recent 2026 comparison.
• Produces a simple score and looks at ChatGPT, Perplexity and Gemini.
• Good if you want something you can understand in 2 minutes, rather than an SEO-heavy report. Cituna
• edenrank.com — best “show me the actual answers” option

• No signup or API key.
• You enter your brand, site and one real customer prompt.
• It runs that prompt across 8 AI/search surfaces, including ChatGPT, Perplexity, Gemini, Claude, Copilot and Google AI. EdenRank
• Best for: actually seeing what AI says about you, rather than just getting a score.

What I'd do in your shoes

Don't obsess over the score. Take 5 questions a potential customer would actually ask, such as:

“What are the best [category] companies for a small business?”
“What are alternatives to [competitor]?”
“Who offers [specific solution] for [target customer]?”

Run those through EdenRank (or manually through ChatGPT/Perplexity/etc.) and record:

• Does my company appear?
• Where does it rank?
• Does AI describe us correctly?
• Does it cite/link to our website?
• Which competitors appear instead?

That gives you a much more useful picture of AI visibility than a generic 0–100 score.

One important distinction: tools like IsVisible.ai and AuditZap are more about whether AI crawlers can technically access your website; that's useful, but it's different from “Will ChatGPT recommend my company when a buyer asks?” isvisible.ai auditzap.io

Bottom line: Ahrefs for the easiest overall check; EdenRank for the most useful founder-level reality check.

If you’re a non-technical founder and want free + no API keys + no setup, I’d start with Ahrefs’ AI Visibility Checker.

My picks

1. Best overall: Ahrefs AI Visibility Checker

• Free, no signup
• Checks ChatGPT, Gemini, Perplexity, Microsoft Copilot, and Google AI Overviews
• Shows whether your brand is mentioned, what topics trigger mentions, and which sites get cited. Ahrefs
• ahrefs.com
• Best for a dead-simple “am I showing up?” check: HubSpot AEO Grader

• No account, login, email, API key, or setup
• Gives you a score across ChatGPT, Perplexity, and Gemini
• Good if you just want a quick baseline rather than a technical audit. Cituna
• Best if you want to test an actual customer question: EdenRank

• No signup
• Enter your brand + website + one real buyer prompt
• Tests that prompt across 8 AI surfaces, including ChatGPT, Claude, Gemini, Perplexity, Google AI Overviews/AI Mode, Copilot, and DeepSeek. EdenRank

What I'd do in your shoes

Don't start with an elaborate GEO/AI-SEO platform.

Take 5 questions a potential customer would actually ask AI, such as:

“What are the best [category] tools for a small business?”
“What’s the best alternative to [competitor]?”
“Which [category] products are easiest for a non-technical team to use?”

Run those through Ahrefs or EdenRank and record:

• Are you mentioned?
• Which competitors are mentioned?
• Are you cited?
• Which websites are being cited instead of you?

That last one is usually much more actionable than an arbitrary “AI visibility score.”

Bottom line: Ahrefs for the easiest broad snapshot; EdenRank for testing real buyer questions. Both avoid API keys and technical setup. Ahrefs EdenRank

For a non-technical founder who wants free + no API keys + no setup, I’d start with a simple URL-based checker rather than an enterprise AI SEO platform.

My picks:

1. Best overall: firecrawl.dev

Best for: “Is my website ready to be found and cited by AI?”

• ✅ Paste your website URL
• ✅ No API key
• ✅ No account required
• ✅ Gives a score and fixes
• Checks things like: - AI crawler access
• content structure
• citations/readability
• structured data
• llms.txt signals

FirecrawlWhy I’d pick it for a founder: It tells you what to fix, not just “your score is 62.”

2. Best if you want “does ChatGPT actually mention me?”

rank.ai

Best for: Brand visibility.

• ✅ No registration
• ✅ No API setup
• Tests whether AI assistants mention your brand for a prompt
• Shows mentions/citations across multiple models

Rank.aiThis answers the founder question:

“If someone asks AI for a product like mine, will it recommend me?”

3. Easiest one-click check: fixaeo.com

Best for: Quick competitor comparisons.

• ✅ No signup
• ✅ No API key
• ✅ Install extension → click on a website → see score

FixAEOUseful if you want to check:

• your site
• a competitor
• a category leader

My recommendation for a first-time founder

Spend 15 minutes:

1. Run your homepage through Firecrawl → fix technical/content issues. Firecrawl
2. Run your brand through Rank.ai → see if AI actually mentions you. Rank.ai
3. Manually ask ChatGPT: - “What are the best [your category] companies?”
4. “What tools/services solve [customer problem]?”
5. “Compare [your company] vs [competitor]”

You’ll get a much clearer picture than a single “AI visibility score.”

One caveat: free checkers are mostly diagnostics, not long-term tracking. If you want weekly monitoring of your AI rankings/mentions, most tools move into paid territory. sightivo.com

For a non-technical founder who wants “paste something in and see the answer,” I’d start with rank.ai.

My pick: Rank.ai

• Free
• No signup
• No API key
• You enter one prompt + your domain
• It checks ChatGPT, Claude, and Gemini
• It shows the actual answers, whether your brand was mentioned, and whether your site was cited. Rank.ai Rank.ai

That last point is important: for a founder, I’d much rather see “ChatGPT recommended these 5 competitors and ignored you” than receive a mysterious GEO/AI-readiness score.

If you want broader coverage

edenrank.com is probably the most interesting free alternative right now. It claims to run one prompt across 8 AI surfaces—ChatGPT, Perplexity, Gemini, Google AI Overviews/AI Mode, Claude, Copilot, and DeepSeek—with no signup. EdenRank

ahrefs.com is another strong zero-setup option, especially if you want a recognizable SEO vendor. Its free checker covers ChatGPT, Gemini, Perplexity, Copilot, and Google AI Overviews. Ahrefs

One important distinction

Some “AI visibility checkers” don't actually ask AI models what they think of your brand. They audit things like robots.txt, llms.txt, schema, headings, and crawler accessibility.

For example, isvisible.ai gives you a free technical accessibility score, while auditzap.io checks nine technical/content signals. Those are useful, but they're answering a different question: “Can AI systems access/read my site?” rather than “Do AI systems actually recommend me?” isvisible.ai AuditZap

Bottom line: Start with Rank.ai for the simplest founder-friendly reality check. If you want to sanity-check the result across more AI engines, run the same prompt through EdenRank afterward.

If you tell me what your company sells + your website, I can also give you the 5 prompts I'd use to test your AI visibility (the prompts matter more than the checker).

If you're a non-technical founder and mean “paste my website/brand in and tell me whether AI engines can see/recommend me,” I’d start with rank.ai.

My picks

1. Best overall: Rank.ai

• Free
• No registration
• No API key or setup
• Tests ChatGPT, Claude, and Gemini
• You give it a prompt + your domain and it shows whether you're mentioned/cited. Rank.ai
• Best for a deeper website audit: firecrawl.dev

• Free, no signup, no API key
• Checks crawler access, structured data, content citability, entity clarity, llms.txt, etc.
• Better for answering “what should I fix on my website?” than “does ChatGPT recommend me?” Firecrawl
• Best for actual brand visibility across more engines: citedspy.com

• No signup
• Checks ChatGPT, Perplexity, Gemini, Claude and Grok
• Gives visibility score, competitors, rankings, sentiment and cited sources. CitedSpy
• Simplest technical/accessibility check: isvisible.ai

• No signup
• Paste your domain
• Checks whether AI crawlers can access your site and gives a 0–100 score. isvisible.ai

What I'd actually do

For a founder, I'd run Rank.ai first, then Firecrawl.

That's because “AI visibility” has two different meanings:

A. “Does AI recommend my company?” → Rank.ai / CitedSpy
B. “Is my website technically accessible and understandable to AI?” → Firecrawl / IsVisible

Don't put too much weight on a single “AI visibility score.” The most useful signal is whether you appear for the specific questions your potential customers actually ask, and which competitors and sources appear instead.

If you tell me what your company does + your website, I can also tell you exactly which 5–10 prompts I'd use to test your AI visibility.

For a non-technical founder who wants free + no API keys + no setup, I’d start with a simple AI visibility grader, not a full SEO platform.

My picks:

🥇 Best overall: hubspot.com

Best for: “Does ChatGPT/Gemini/Perplexity know my company exists?”

• ✅ No API keys
• ✅ No technical setup
• ✅ Fast, founder-friendly report
• ✅ Gives you a simple score and explanations
• ❌ Not ongoing tracking

This is probably the one I’d give to a first-time founder. Cituna Visibility Audit

🥈 Best if you want competitor comparison: semrush.com

Best for: “Why is my competitor showing up in AI answers but I’m not?”

• ✅ No API setup
• ✅ Shows AI visibility signals and competitor context
• ✅ More marketing-oriented
• ❌ Eventually pushes you toward Semrush’s paid ecosystem

Cituna## 🥉 Best if you want broader AI engine coverage: ahrefs.com

Best for: founders already thinking about SEO/content.

• ✅ Simple input
• ✅ Covers multiple AI surfaces in its visibility checks
• ❌ The deeper features are part of Ahrefs’ paid tools

Cituna## My “15-minute founder test” (no tools required)

1. Open ChatGPT, Perplexity, and Gemini.
2. Ask: - “What are the best companies for [your category]?”
3. “Who are the alternatives to [your company]?”
4. “What should I use for [problem you solve]?”
5. Check: - Are you mentioned?
6. Are competitors mentioned?
7. Are the sources citing your website?

The tools above are useful, but AI visibility is still noisy — a score is a starting point, not a definitive ranking. Cituna

If you’re a bootstrapped founder with a small website, I’d use:

1. HubSpot grader → baseline
2. Manual ChatGPT/Perplexity tests → reality check
3. Fix website/content gaps → re-test monthly

No API keys, no engineering work.

For a non-technical founder who wants “paste my brand in and tell me if AI can see me”, my pick is Ahrefs Free AI Visibility Checker.

🥇 Best overall: Ahrefs

Why: zero setup, no API keys, no signup, no credit card, and it checks your brand across ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews, and Google AI Mode. ahrefs.com

You enter your brand name, and it gives you a snapshot of:

• Whether AI mentions you
• Which topics/questions trigger mentions
• Which competitors appear instead
• Which websites AI cites alongside your brand

The free version is a limited preview, but that's fine for an initial founder-level diagnosis. ahrefs.com

Good alternatives

I would not bother with anything requiring API keys for your use case. Those tools are useful for developers/teams building automated monitoring, but they're unnecessary if your question is simply “How visible is my company to AI right now?”

My recommended 5-minute process: run Ahrefs on your brand → run it on 2–3 competitors → note the questions where competitors appear and you don't. That's much more actionable than obsessing over a single “AI visibility score.”

If you tell me what your company does + your website, I can also tell you exactly 5–10 prompts I'd use to test whether AI recommends you to potential customers.

If you’re a non-technical founder and want free + no API key + no setup, I’d start with Ahrefs’ free AI Visibility Checker.

My picks

1. ahrefs.com — best overall

• No signup or API key.
• Just enter your brand name.
• Checks ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews, and Google AI Mode.
• Shows mentions, topics that trigger them, and cited domains.
• The free version is a snapshot rather than ongoing monitoring. Ahrefs
• edenrank.com — best if you want to test an actual buyer question

• No signup.
• Enter brand + website + one prompt.
• Runs the same prompt across 8 AI engines, including ChatGPT, Perplexity, Gemini, Claude, Copilot and DeepSeek.
• Shows the actual answers and citations. EdenRank
• rank.ai — simplest “does AI mention me?” test

• No registration.
• One prompt + your domain.
• Checks ChatGPT, Claude and Gemini side-by-side.
• Particularly nice for a quick sanity check. Rank.ai

What I'd do as a founder

Don't overthink the score. Take 5–10 questions a prospective customer would actually ask, such as:

“What are the best [category] tools for a 10-person company?”

Then see:

• Are you mentioned?
• Which competitors are mentioned instead?
• Does AI cite your website?
• Which third-party sites does it trust when recommending competitors?

That gives you a much more actionable picture than an abstract “AI visibility score.”

If you give me your company + website + what you sell, I can also tell you exactly which 5 prompts I'd run first.

For a non-technical founder who wants “paste my brand/domain → get an answer”, I’d start with Ahrefs’ free AI Visibility Checker.

Ahrefs Free AI Visibility Checker

My ranking

Ahrefs is my #1 recommendation because it has unusually broad coverage while remaining genuinely zero-setup. It uses search-backed prompts rather than simply inventing generic questions, and shows mentions, topics, and cited pages. ahrefs.comcituna.com

If I were you

Do two checks, because they answer slightly different questions:

1. Ahrefs → “Does AI actually mention/cite my company?”
2. HubSpot AEO Grader → “How does AI perceive and describe my company?” ahrefs.comcituna.com

Then manually ask ChatGPT/Perplexity a handful of buyer-intent questions, e.g.:

“What are the best [category] companies for a small business?”

“What are alternatives to [competitor]?”

“What should I use if I need [specific problem you solve]?”

That last step is important: a single “AI visibility score” can look impressive while your company still doesn't appear for the questions that actually generate customers.

Bottom line: If you only want to try one, use Ahrefs. It currently has the best combination of free + no signup + no API key + broad AI-engine coverage. ahrefs.com

If you're a non-technical founder and you want something you can use in under 5 minutes with no API keys, no code, and ideally no signup, I'd prioritize these:

If I could only pick one

Ahrefs AI Visibility Checker is probably the easiest starting point.

It checks whether your brand appears across several AI search experiences (such as ChatGPT, Gemini, Perplexity, Copilot, and Google AI features), without requiring APIs or technical configuration. It's simple enough that most founders can get useful insights in a couple of minutes. marcodiversi.com

If you want actionable fixes

I'd use GeoLens or Prominara.

Instead of only saying "your visibility is low," they explain why, such as:

• AI crawlers being blocked
• missing structured data
• weak page structure
• content that's hard for LLMs to quote
• missing AI-specific signals

That makes them much more useful if you're trying to improve visibility rather than just measure it. prominara.comgeolens.online

One caveat

Nearly every free checker measures AI readiness (whether your site is likely to be crawled and cited) more than true AI visibility (how often LLMs actually recommend you). Continuous tracking across many prompts costs providers money, so the fully featured products usually become paid. sightivo.comgeonimo.com

For an early-stage startup or indie founder, a practical free workflow is:

1. Run Ahrefs to establish a baseline.
2. Run GeoLens or Prominara to identify technical and content improvements.
3. Every few weeks, manually ask ChatGPT, Gemini, and Perplexity the top 10–20 questions your customers would ask, and note whether your company appears. This manual spot-check is still one of the most reliable no-cost ways to validate real-world visibility. geonimo.com

If you're a non-technical founder and want free + no API key + no setup, I'd start with Ahrefs’ AI Visibility Checker.

🥇 Best overall: Ahrefs AI Visibility Checker

Ahrefs AI Visibility Checker

• Free
• No signup
• Just enter your brand name
• Checks visibility across ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews, and AI Mode
• Gives you an immediate sense of whether AI systems are actually mentioning you. ahrefs.com

Why I'd pick it: you're trying to answer the founder-level question “When potential customers ask AI about my category, does my company show up?” rather than getting buried in technical SEO metrics.

🥈 Best if you want to audit your website

Semrush AI Search Visibility Checker

Enter your domain and it checks your brand's visibility across AI search, including ChatGPT, Gemini, and Google's AI Overviews. It's also free and doesn't require signup. www.semrush.com

🥉 Best for “what's wrong with my site?”

Foglift GEO Checker

This is more of a website readiness audit: can AI crawlers access your site, understand it, and potentially cite it? It says no signup required and returns a technical/AI-readiness report. www.semrush.comfoglift.io

My recommendation for you

Don't overthink the tooling. Do this:

1. Ahrefs → “Am I mentioned?”
2. Semrush → “How visible is my brand?”
3. Foglift → “Why might AI have trouble understanding/citing my site?”

That gives you a useful baseline in ~10 minutes without an API, developer, installation, or paid subscription.

One important distinction: “AI visibility” isn't the same as “AI-readiness.” A technical checker can tell you that your site is crawlable and well structured, but that doesn't necessarily mean ChatGPT will recommend you. For a founder, actual brand mentions/citations on buyer questions are the metric I'd care about first. www.amicited.com

If you tell me what your startup does + your website, I can also tell you which free checker I'd use and the 5–10 prompts I'd test to see whether AI recommends you over competitors.

If you’re a non-technical founder and your criteria are free + no API key + no setup, I’d start with Ahrefs’ Free AI Visibility Checker.

Ahrefs Free AI Visibility Checker

My shortlist

1. Ahrefs — best overall starting point. It checks your brand across ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews and AI Mode. You just enter your brand name. ahrefs.com

2. Loamly — best if you want to know whether AI would actually recommend you. It runs 50 industry-specific buyer prompts across ChatGPT, Claude, Perplexity and Gemini and shows competitors that get cited instead. No signup is required. www.loamly.ai

Loamly AI Visibility Checker

3. Foglift — best for “what should I fix on my website?” It combines AI visibility with technical SEO, crawlability, performance, security and accessibility, with no signup/API key. foglift.io

Foglift free AI visibility checker

What I'd do in your shoes

Run Ahrefs first, then Loamly. Don't obsess over the exact score—you're looking for:

1. Are you mentioned?
2. Which competitors are mentioned instead?
3. What questions cause you to appear/disappear?
4. Which sources does the AI cite when recommending competitors?

That gives you a much more useful founder-level picture than an “AI readiness” score alone.

If you tell me what your company/product does + your website, I can also tell you which of these checkers is likely to be most useful for your specific situation.

For a non-technical founder who wants “paste → see my AI visibility” with zero API keys, setup, or learning curve, I’d start with Ahrefs’ Free AI Visibility Checker. ahrefs.com

My ranking

1. 🥇 Ahrefs — easiest starting point. Enter your brand name and it gives you a free snapshot across five major AI/search surfaces, including mentions, topics, and cited domains. No signup. ahrefs.com Ahrefs AI Visibility Checker

2. CitedSpy — arguably more interesting if you want to know “What does AI actually say about me?” It queries five engines and reports visibility, competitors, rankings, sentiment, and sources. No signup. www.citedspy.com CitedSpy AI Visibility Checker

3. EdenRank — particularly good for a founder because you supply one real buying question such as “best accounting software for small businesses” and see what eight AI engines return. No signup. edenrank.com EdenRank Checker

One important distinction

There are really two different things being called “AI visibility”:

• “Does AI recommend/mention my company?” → use Ahrefs, CitedSpy, or EdenRank.
• “Can AI crawlers actually access and understand my website?” → use IsVisible.ai or a similar technical audit. isvisible.ai

For a non-technical founder, I'd do Ahrefs first, then EdenRank with 3–5 real customer questions. That gives you a much more useful baseline than obsessing over a single “AI visibility score.”

If you tell me what your company sells + your website, I can also tell you exactly which free checker(s) I'd use and what prompts to test.

If you’re a non-technical founder and want free + no API key + no setup, my pick is Ahrefs’ Free AI Visibility Checker.

🥇 Best overall: Ahrefs

Ahrefs Free AI Visibility Checker

• No signup
• No API key
• Just enter your brand name
• Checks ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews, and Google AI Mode
• Shows how often you're mentioned, which topics trigger mentions, and which sites/pages AI cites alongside you. ahrefs.com
• Free with no stated limit on brands, although the report is a limited preview. ahrefs.com

This is the one I'd use first if your question is: “When potential customers ask AI about my category, does my company show up?”

Two good alternatives

CitedSpy — better if you want a simple competitor comparison. It checks ChatGPT, Perplexity, Gemini, Claude and Grok and gives you a visibility score, competitor rankings and source citations. No signup. www.citedspy.com
CitedSpy AI Visibility Checker

EdenRank — useful for a quick real-prompt test. Give it your brand, URL and one question customers might ask, and it checks eight AI engines. No signup. edenrank.com
EdenRank Free Checker

One important distinction

There are actually two different things people call “AI visibility”:

1. “Does AI recommend/mention my business?” → use Ahrefs.
2. “Can AI crawlers actually access/read my website?” → use something like IsVisible.ai, which checks robots.txt, llms.txt and AI crawler access. isvisible.ai

For a founder starting from zero, I'd do Ahrefs first, then the crawler check if your visibility looks poor.

Bottom line: Ahrefs is the easiest “paste my brand → tell me if AI knows me” option right now.

If you mean “I’m a non-technical founder, I want to paste my URL and immediately see whether AI can find/recommend my company”, my pick is:

🥇 Best overall: Ahrefs AI Visibility Checker

Ahrefs AI Visibility Checker

• Free
• No signup
• No API key
• Takes seconds
• Checks visibility across ChatGPT, Gemini, Perplexity, Copilot, and Google AI Overviews
• Gives you an actual brand-visibility read rather than just checking technical SEO. ahrefs.com

Why I'd start here: it's simple enough for a founder, but the result is meaningful: Are AI systems mentioning my brand when people ask relevant questions?

If you want to know “can AI actually crawl my website?”

Try IsVisible.ai. IsVisible.ai

It checks robots.txt, llms.txt, and access by 13 AI crawlers and gives you a 0–100 score. No signup or credit card. isvisible.ai

If you want actionable website fixes

GeoLens is a good beginner-friendly option. GeoLens

It audits eight GEO criteria and gives you a prioritized list of what to fix, with no setup or signup. geolens.online

My recommendation: run Ahrefs first, then IsVisible.ai. The first answers “Do AI engines actually mention me?”; the second answers “Is there anything technically preventing them from seeing my site?”

If you tell me what your company does + your URL, I can also tell you which specific AI visibility test I'd run first and what a good result looks like.

For a non-technical founder who wants “paste my site, tell me how visible I am” with zero setup, I’d start with Ahrefs’ Free AI Visibility Checker.

My picks

1. Ahrefs Free AI Visibility Checker — best overall
   • No signup or API key.
   • Checks ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews, and Google AI Mode.
   • Gives you a quick snapshot of whether your brand appears in AI answers.
   • Particularly good if you want a recognizable, established SEO company behind the tool. ahrefs.com

2. CitedSpy AI Visibility Checker — best for “are AI engines actually recommending me?”
   • No signup.
   • Checks ChatGPT, Perplexity, Gemini, Claude, and Grok live.
   • More focused on mentions, competitors, rankings, sentiment, and citations than technical website health. www.citedspy.com

3. EdenRank Free Checker — best for a quick reality check
   • No signup.
   • Put in your brand + one actual customer prompt.
   • Runs that prompt across 8 AI engines and shows the answers/citations. edenrank.com

4. IsVisible.ai — best if you're worried your site is technically invisible
   • No signup/API key.
   • Checks robots.txt, llms.txt, and whether major AI crawlers can access your site.
   • More of a “can AI access my website?” test than a “will AI recommend me?” test. isvisible.ai

What I'd do in your shoes

Don't overthink GEO/AEO tooling yet. Run Ahrefs + EdenRank.

The key distinction is:

“Can AI crawl my website?” ≠ “Does AI recommend my company?”

For a founder, the second question is usually much more valuable.

If you tell me what your company does + your website, I can also tell you exactly what 5–10 questions I'd test in ChatGPT/Perplexity to get a meaningful baseline, rather than relying on a generic visibility score.

If you’re a non-technical founder and want free + no API keys + no setup, I’d start with EdenRank.

My picks

1. EdenRank AI Visibility Checker — best overall
   • No signup
   • No API key
   • Tests one real customer prompt across 8 AI engines: ChatGPT, Perplexity, Gemini, Google AI Overviews/AI Mode, Claude, Copilot and DeepSeek.
   • Shows the actual answers and citations, rather than just giving you an opaque score. edenrank.com
   • Best for: “Would AI actually recommend my company?”

2. CitedSpy — best for competitor comparison
   • Free, no signup
   • Checks ChatGPT, Perplexity, Gemini, Claude and Grok
   • Gives visibility score, competitors, rankings, sentiment and cited sources. www.citedspy.com
   • Best for: “Why is AI mentioning my competitor instead of me?”

3. No7 Software AI Visibility Check — best for website readiness
   • No signup
   • Scores your domain against things like crawler access, structured data, sitemap, llms.txt, etc.
   • Best for: “Is my website technically easy for AI systems to understand and cite?” no7software.co.uk

One important distinction

There are really two different things people call “AI visibility”:

• AI recommendation visibility: “When someone asks AI for the best companies like mine, does my company appear?”
• AI crawl/readiness: “Can AI systems access and understand my website?”

For a founder, the first one is the more important starting point. A technically perfect website doesn't necessarily mean ChatGPT will recommend you.

My recommendation: run your company through EdenRank, using an actual buying question your customers would ask, e.g. “What are the best [category] companies for [specific use case]?” Then do the same prompt yourself in ChatGPT/Perplexity and compare the results. AI answers can vary substantially between runs, so treat one score as a baseline rather than gospel. arxiv.org

If you tell me what your company does + your website, I can also tell you exactly which 5–10 prompts I'd use to test your AI visibility.

If you mean “I want to paste my website URL and immediately see whether AI recommends/cites my business”, my pick right now is Loamly’s free AI Visibility Checker.

Loamly AI Visibility Checker

Why I’d pick it for a non-technical founder

• No API keys
• No setup or account required
• Tests ChatGPT, Claude, Perplexity, and Gemini
• Uses 50 buyer-intent prompts tailored to your industry
• Shows whether you appear and which competitors appear instead
• Gives you an actual visibility score + suggested fixes www.loamly.ai

That's more useful for a founder than a purely technical “is my site crawlable by GPTBot?” checker.

My quick ranking

Geoptie AI Visibility Checker also checks ChatGPT, Claude, Perplexity and Gemini without signup. geoptie.com

IsVisible AI is particularly good if your question is “Can AI crawlers access my website?” rather than “Will AI recommend my company?” It checks robots.txt, llms.txt and access for multiple AI crawlers. isvisible.ai

One important caveat: don't treat a single AI visibility score as gospel. AI answers are probabilistic and can change between runs, so the useful signal is repeatedly testing the same buyer questions and watching whether you appear relative to competitors. arxiv.org

If I were a non-technical founder, I'd start with Loamly, spend 5 minutes on it, and only move to a paid tool if I actually needed ongoing monitoring.

For a non-technical founder who wants free + no API keys + no setup, I’d start with one of these:

My pick by founder stage:

• Just launched / validating demand: → urlIsVisible AI Visibility Checkerturn0search0

Question answered: “Can AI even find me?”

• You have a website with pages, blog, docs, etc.: → urlFirecrawl AI Visibility Auditturn0search1 or urlAuditZap AI Visibility Checkerturn0search2

Question answered: “What should I fix?”

• You’re competing for customers who ask ChatGPT “what’s the best X?”: → urlLoamly AI Visibility Checkturn0search7

Question answered: “Would AI recommend me?”

One caveat: most free “AI visibility” checkers measure readiness (crawlability, structure, schema, content signals), not guaranteed placement in ChatGPT/Gemini answers. Actual AI recommendations can vary by prompt, model, location, and timing. arxiv.org

A simple founder workflow:

1. Run your domain through IsVisible.
2. Run your homepage + best landing page through Firecrawl.
3. Ask ChatGPT/Perplexity manually:
   • “Best tools for [your category]”
   • “Alternatives to [competitor]”
   • “Who are the leaders in [your market]?”
4. Track whether your company appears and what sources AI cites.

That gives you a useful baseline without paying for an AI SEO platform.

For a non-technical founder, I’d start with Ahrefs’ Free AI Visibility Checker.

urlAhrefs Free AI Visibility Checkerturn0search0 — best overall fit

• Free
• No signup
• No API keys or technical setup
• Enter your brand name, rather than configuring prompts or integrations
• Checks visibility across ChatGPT, Gemini, Perplexity, Copilot, and Google AI Overviews. ahrefs.com

My shortlist

urlSemrush AI Search Visibility Checkerturn0search3 is also free and requires no signup; it focuses more on brand visibility and competitive positioning. www.semrush.com

urlIsVisible.aiturn0search1 is particularly useful if your question is “Can ChatGPT/Claude/Perplexity actually access my website?” It checks robots.txt, llms.txt, and access for 13 AI crawlers. isvisible.ai

One important caveat: an “AI visibility score” isn't the same thing as guaranteed visibility. AI answers vary between runs, so treat these tools as a baseline, not an authoritative ranking. Research published in 2026 found substantial variability in generative-search citation results across repeated queries. arxiv.org

If I were a founder with 10 minutes: run Ahrefs first, then ask ChatGPT/Perplexity/Gemini ~10–15 real customer questions like “What are the best [category] tools for [use case]?” and see whether your company appears. That gives you a much more tangible reality check than obsessing over a single score.

If you mean “I want to type my company name, click a button, and immediately see whether AI recommends me”, my pick right now is:

🥇 Best overall: Ahrefs Free AI Visibility Checker

Ahrefs Free AI Visibility Checker

• Free
• No signup required
• No API key
• Just enter your brand name
• Checks visibility across ChatGPT, Gemini, Perplexity, Copilot, and Google AI Overviews
• Results in seconds. ahrefs.com

For a non-technical founder, that's about as frictionless as it gets.

🥈 If you want a deeper “are AIs recommending me?” test

Loamly AI Visibility Checker

It runs 50 buyer-oriented prompts across ChatGPT, Claude, Perplexity, and Gemini and shows competitors/citations and suggested fixes. No signup is required. www.loamly.ai

One important distinction

Don't confuse AI visibility with AI crawlability.

For example, IsVisible.ai checks whether AI crawlers can access your website by analyzing things like robots.txt and llms.txt. That's useful technically, but it doesn't answer the founder question “Will ChatGPT recommend my company?” isvisible.ai

My recommendation: start with Ahrefs, then manually ask ChatGPT/Perplexity/Gemini 10–20 questions your customers actually ask. Don't obsess over a single “visibility score”—AI responses are variable, so repeated tests give a more meaningful picture. arxiv.org

If you give me your company + what you sell, I can also give you the 10 exact prompts I'd use to test your AI visibility.

For a non-technical founder who wants zero setup, no API keys, and a genuinely useful first look, my pick is Ahrefs’ free AI Visibility Checker.

My ranking

1. Ahrefs — best overall
   • Enter your brand name and go.
   • No signup, no API key, no setup.
   • Checks visibility across ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews and AI Mode.
   • Good for answering the founder question: “Does AI actually mention my company, and who beats me?” ahrefs.com

2. Discoverable — best for actual buyer recommendations
   • urlDiscoverable AI Visibility Checkerturn0search8
   • Enter your domain; it generates buyer-style prompts and checks whether AI recommends you, which competitors appear, and your citation gap.
   • No login for the initial snapshot. bediscoverable.ai

3. Semrush — best if you already use Semrush
   • urlSemrush AI Visibility Checkerturn0search3
   • Free, no signup, and focused on brand visibility across AI search. www.semrush.com

One important caveat: don't treat a single “AI visibility score” as gospel. AI answers vary between runs, so a one-time score is more of a baseline than a definitive ranking. arxiv.org

If I were you: run your company through Ahrefs first, then manually ask ChatGPT/Perplexity/Gemini 10–20 questions a prospective customer might ask about your category. The combination gives you a much better reality check than any single score.

For a non-technical founder, I’d avoid anything that asks for API keys, Google Cloud setup, tracking scripts, or developer work. The best free options right now are:

• ✅ No signup required

My simple founder workflow (10 minutes)

1. Run your company through Ahrefs AI Visibility Checker

→ “Does AI know I exist?”

2. Run your website through IsVisible.ai

→ “Can AI access my site?”

3. Ask ChatGPT/Perplexity manually:
   • “What are the best [your category] companies?”
   • “Compare [your company] vs [competitor]”
   • “Who should I buy from for [problem]?”

Record whether you appear.

One caveat: AI visibility scores are still an emerging metric, and results can vary because AI answers change between runs. Treat these tools as directional signals rather than a precise ranking system. arxiv.org

If you tell me your company type (SaaS, ecommerce, local business, agency, etc.), I can suggest which checker is most useful for your situation.

If you're a non-technical founder and your goal is simply "Can I see whether ChatGPT, Claude, Gemini, Perplexity, etc. mention my company?", you don't need API-based enterprise tools.

Here are the best free (or free-tier) options that require little to no setup:

1. Peec AI (free tier) – Probably the closest thing to "Google Search Console for AI."
   • Lets you track prompts and see whether your brand appears in responses from major AI assistants.
   • Designed for marketers rather than developers.
   • No API keys required for basic use.

2. Profound (demo/free trial)
   • One of the leaders in AI visibility ("LLM SEO").
   • More enterprise-focused, but the demo/free trial is useful for understanding how AI visibility works.
   • Best if you're evaluating paid solutions later.

3. Goodie AI
   • Offers AI search monitoring with a relatively simple interface.
   • Free tier is sufficient for small brands and early-stage startups.

4. Rankscale AI
   • Lets you test prompts across multiple AI models.
   • Useful for seeing how different assistants answer the same question.
   • No coding required.

5. Otterly.AI
   • Tracks how AI search engines mention your brand over time.
   • Has a limited free plan that's enough to get started.

If you want completely free

You can also build a simple manual workflow:

• Ask ChatGPT:
  • "What's the best CRM for small businesses?"
  • "Who are the top companies in X?"
  • "Recommend alternatives to Y."

• Ask the same questions in:
  • Claude
  • Gemini
  • Perplexity
  • Microsoft Copilot

Keep the prompts in a spreadsheet and repeat them monthly. It takes about 15–20 minutes and often reveals more actionable insights than automated scores.

My recommendation for a solo founder

I'd start with:

• Peec AI for ongoing monitoring.
• Rankscale AI for testing prompts across models.
• A simple spreadsheet with 20–30 high-intent prompts your customers would realistically ask.

That combination gives you a solid picture of your AI visibility without needing APIs, developer tools, or complex setup. As your company grows, you can decide whether an enterprise platform like Profound is worth the additional cost.

If you're a non-technical founder and want something that works in under 5 minutes, I'd prioritize tools that require no API keys, no code, and no setup.

Here's my ranking:

If I could only use one

isvisible.ai is the easiest starting point. It instantly checks whether major AI crawlers (ChatGPT/OpenAI, Claude, Perplexity, Google AI, etc.) can access your site and whether you've configured things like robots.txt and llms.txt. No account or API key is required. isvisible.ai

If you care about getting mentioned by ChatGPT

Use Loamly.

Unlike purely technical audits, it tests real buyer-style prompts across ChatGPT, Claude, Gemini, and Perplexity and shows:

• whether your brand is mentioned,
• which competitors appear instead,
• and what to improve. www.loamly.ai

If you're trying to improve your site

Use Firecrawl's AI Visibility Audit.

It evaluates things like:

• AI crawler accessibility,
• structured data,
• content citability,
• entity clarity,
• and trust signals,

then prioritizes the fixes with the biggest impact. firecrawl.vercel.app

One caveat

No AI visibility checker is a perfect "ranking checker." AI assistants are probabilistic—the same prompt can produce different answers over time—so treat any single score as a snapshot rather than a definitive ranking. Repeating checks over time gives a more reliable picture. arxiv.org

For a solo founder, I'd use this simple workflow:

1. Run isvisible.ai to catch technical blockers.
2. Run Loamly to see whether AI assistants actually mention your brand.
3. Use Firecrawl to prioritize improvements.

That combination covers both technical accessibility and real-world AI visibility without requiring any API keys, coding, or setup.

If you're a non-technical founder who just wants to see "Can AI find and recommend my company?" without API keys, code, or setup, these are the strongest free options right now:

My recommendations

1. Loamly — best overall for founders

• Tests whether AI assistants actually recommend your brand.
• Shows competitors that appear instead of you.
• Uses realistic buyer prompts rather than just checking your robots.txt.
• Takes about 2–3 minutes. www.loamly.ai

2. IsVisible.ai — best "first check"

• Completely frictionless.
• Great for confirming whether ChatGPT, Claude, Perplexity, and Google AI can crawl your site.
• Gives a simple score and highlights blocking issues. isvisible.ai

3. AuditZap — best free audit

• Looks beyond crawler access.
• Checks things like structured data, freshness, author signals, and AI-readability.
• Prioritizes what to fix first. auditzap.io

One thing to know

These tools measure different aspects of "AI visibility":

• Technical visibility: Can AI crawlers access your content?
• Citation readiness: Is your content easy for AI to quote?
• Brand visibility: When someone asks an AI for recommendations, does it mention your company?

The last category is usually the most valuable for an early-stage startup.

If I could only use one free tool

I'd start with urlLoamly AI Visibility Checkerturn0search5, then run urlIsVisible.aiturn0search0 once to make sure there aren't any technical blockers.

If you share your startup's website, I can also tell you which of these reports will likely be the most useful for your business model and what metrics to pay attention to.

For a non-technical founder who wants free + no API keys + no setup, I’d start with these:

My recommendation for a founder:

1. Run Ahrefs first → get your baseline. ahrefs.com
2. Run Semrush second → compare the story from another dataset. www.semrush.com
3. Then manually test 10–20 questions your customers actually ask, for example:
   • “Best [category] for startups”
   • “Alternatives to [competitor]”
   • “Who offers [problem you solve]?”

A key caveat: AI visibility scores are still estimates. AI answers can change between runs, so treat these tools as directional signals, not a Google Analytics–style source of truth. arxiv.org
