ChatGPT answers, unedited

For a quick, one-off competitor URL check, I’d use Citation Radar. It’s specifically built around entering a URL and seeing where that brand/competitor gets cited across multiple AI engines, with a free tier and no credit card required. It covers ChatGPT, Perplexity, Gemini, Claude, and Grok. Citation Radar

citationradar.ai

A few good alternatives:

• Ahrefs Free AI Visibility Checker — strongest if you want a quick benchmark across ChatGPT, Gemini, Perplexity, Copilot and Google AI surfaces. It accepts competitor names/brands and shows cited domains/pages. No signup for the free snapshot. Ahrefs
• Citegrade — better if you already have a specific query and want to see whether a particular URL gets cited, including the citation position and which competitors were cited instead. Citegrade
• Citegrove — useful for an agency-style competitor comparison; its free scan checks ChatGPT, Perplexity and Gemini and reports cited URLs. Citegrove
• RankBits — very lightweight: URL in, three buyer prompts, live checks across ChatGPT/Google/AI Overviews, with a shareable report. RankBits

My pick for your use case: Citation Radar if the goal is “show me where this competitor is getting AI citations and what we're missing.” Ahrefs if the goal is a fast, credible-looking agency snapshot across more AI surfaces.

If you give me the competitor URL, I can also tell you which of these is best for that particular site and what I'd measure in the one-off audit.

For a quick, one-off competitor URL check, I’d use CitedSpy’s free AI Search Citation Checker. It runs a query live across ChatGPT, Perplexity, Gemini, Copilot, and Google AI Mode, shows the actual cited URLs, and requires no signup. CitedSpy

citedspy.com

A couple of alternatives:

• Citegrade — better if you already know the exact query you want to test against a competitor URL; it checks ChatGPT + Perplexity and identifies competing cited pages. Citegrade citegrade.com
• CiteSpy — useful for an agency-style mini audit; its free scan covers ChatGPT, Claude, Gemini and Perplexity and gives exact cited URLs, but the free tier is limited to one scan/3 queries. CiteSpy citespy.app
• GenMention — handy if you want a quick URL/brand check rather than detailed query-by-query research; it has a free instant check and tracks ChatGPT, Gemini and Perplexity. GenMention genmention.com

For your specific “one competitor URL, quick agency deliverable” use case: CitedSpy first. It gives you the cleanest evidence trail: query → AI answer → exact cited competitor URL. CitedSpy

For a quick one-off competitor URL check, I’d use Ahrefs’ free AI Visibility Checker. It’s no-signup and covers ChatGPT, Gemini, Perplexity, Copilot, and Google AI surfaces, making it useful for a fast benchmark. Cituna RankTopAI

If you specifically need URL-level citation checking, SourceWatch is worth trying: it accepts one URL and reports whether AI engines cite that page. sourcewatch.ai

Quick pick: Ahrefs for broad competitor benchmarking; SourceWatch for a specific page. citeturn0search1turn0search2

For a quick one-off competitor URL AI citation check, I’d use a lightweight free checker rather than a full GEO/SEO platform.

My shortlist:

1. Best overall quick agency check: yogoo.ai

• Paste a domain and get an AI visibility score.
• Useful for competitor benchmarking: who AI cites instead, which prompts trigger visibility, and engine breakdowns.
• Good fit for a strategist making a fast client/competitive snapshot. Yogoo
• Best if you specifically need “does AI cite this URL?”: sourcewatch.ai

• More URL-focused.
• Checks whether AI engines mention/recommend the brand and whether the site is used as a citation source. SourceWatch
• Best no-friction ChatGPT-focused spot check: rankbits.com

• No-signup style workflow.
• Shows mentions, citations, competitors, and prompt-level results for ChatGPT checks. RankBits
• Best for a repeatable agency workflow (if the free tier is enough): genmention.com

• More like a monitoring tool.
• Tracks AI mentions/citations over time and includes competitor insights. GenMention

For a one-off competitor URL, I’d do:

• Run the competitor through Yogoo → get the broad AI visibility picture.
• Run the exact URL through SourceWatch → see citation/readability gaps.
• Manually test 5–10 buyer prompts in ChatGPT/Perplexity and record: - Was competitor mentioned?
• Was the URL cited?
• Which pages/domains were cited instead?

One caveat: these tools are measuring sampled prompts, not a complete index of everything AI systems know. Citation tracking is still an approximation because AI answer engines don’t expose a universal “all queries where this URL appeared” database. citeflow.io

For an agency strategist, I’d pick Yogoo for the fastest competitive snapshot and SourceWatch for a URL audit.

For a quick, one-off competitor URL check, I’d use Citegrade first. It lets you paste a specific page URL + target query, checks ChatGPT and Perplexity in real time, and shows whether the page was cited, its citation position, and which competitor sources appeared instead. It’s free. Citegrade

citegrade.com

Best free options

• Citegrade — best for a specific competitor URL. Most directly matches your “is this page getting cited?” use case. Citegrade
• Citegrove — good if you want a broader competitor benchmark; its free scan checks citations across ChatGPT, Perplexity and Gemini. Citegrove
• Yogoo — better for a quick agency-style brand vs. competitors snapshot, including citation rates and prompts where competitors win. Yogoo
• SourceWatch — useful for a fast URL-level AI visibility audit; it says the free check takes about 15 seconds and requires no login. SourceWatch

My pick: If you're literally handing me competitor.com/page and want to know “Is AI citing this page, for what queries, and who beats it?”, go with Citegrade. For a client-facing competitor landscape, I'd use Yogoo or Citegrove.

One caveat: these are spot checks, not statistically robust measurements. AI answers vary by prompt, model, location, and time, so don't present a single free-check result as a definitive citation rate.

For a quick, one-off competitor URL check, I’d use ahrefs.com first.

• Best overall: Ahrefs — free, no signup, and checks ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews, and AI Mode. It also shows the domains and specific pages being cited, which is the useful part for competitor research. Ahrefs
• Best if you specifically want “enter URL → citation report”: citationradar.ai — built around competitor citation gaps and accepts a domain directly. It covers ChatGPT, Perplexity, Gemini, Claude, and Grok. Citation Radar
• Good lightweight alternative: citegrove.com — free scan, no account, focused specifically on which URLs ChatGPT, Perplexity, and Gemini cite for buyer-intent queries. Citegrove

My agency workflow: run the competitor through Ahrefs first, then use Citation Radar/Citegrove if you need a second data point. For a one-off client snapshot, I wouldn't pay for a full monitoring platform.

If you give me the competitor URL, I can also tell you exactly which free checker I'd use and what prompts to test.

For a quick, one-off competitor URL check, I’d use citegrade.com.

• Best for: “Is this exact competitor page being cited?”
• You enter the URL + target query, and it checks ChatGPT and Perplexity live, showing citation position and which competitors were cited instead. It says the checker is free. Citegrade
• Best agency workflow: run 5–10 realistic buyer queries against the competitor URL, then record cited / not cited + cited competitor URLs.

If you want broader competitor intelligence across multiple AI engines, citedspy.com is a stronger free one-off option: it checks ChatGPT, Perplexity, Gemini, Copilot and Google AI Mode and returns the actual cited URLs. citedspy.com

My pick: Citegrade for a single competitor URL; CitedSpy for a quick multi-engine agency snapshot. citeturn0search3turn0search18

For a quick, one-off agency check on a competitor URL, I’d use Ahrefs’ free AI Visibility Checker first. It’s no-signup and checks ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews, and AI Mode, including which domains/pages get cited. Ahrefs

My picks

• Best overall: ahrefs.com — fastest credible snapshot; good for a competitor benchmark.
• Best if you specifically care about the URL being cited: citegrade.com — enter the page URL + a target query and it checks ChatGPT and Perplexity for the exact citation and competing sources. Citegrade
• Best broad free scan: yogoo.ai — checks citation/visibility across ChatGPT, Perplexity, Claude, Gemini and Google AI Overviews, with competitor comparisons. Yogoo
• Best if you need Google AI Overviews specifically: ahrefs.com — shows which pages Google cites and which sources beat the competitor. Ahrefs

For an agency strategist, I'd do Ahrefs first, then Citegrade on 5–10 high-value queries. That gives you both the broad competitor snapshot and evidence of which exact URLs are winning citations.

One caveat: a free checker is generally a snapshot, not true ongoing tracking; that's the main limitation across the free tools. cituna.com

For a quick, one-off competitor URL check, I’d use Ahrefs’ free AI Visibility Checker first. It’s no-signup and checks ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews, and AI Mode, including the domains/pages being cited. Ahrefs

ahrefs.com

My shortlist

• Best overall: Ahrefs — easiest agency-friendly snapshot; good for seeing which pages/domains AI cites alongside the competitor. Ahrefs
• Best if you specifically need the URL as input: EdenRank — enter a brand URL + a commercial prompt, then get answers and citations across 8 AI surfaces. Free/no signup. EdenRank
• Best lightweight citation-only check: AI Citation Monitor — free snapshot across ChatGPT, Perplexity, Gemini and Google AI Overviews, with cited URLs shown separately from mere mentions. AI Citation Monitor
• Best for a broader competitor/agency report: CitedSpy — accepts a domain and gives competitor share-of-voice, prompt-level results, and cited sources. CitedSpy

For your exact use case: put the competitor's domain into Ahrefs, then run 5–10 prompts that mirror the client's buyer journeys (e.g. “best [category] software,” “[competitor] alternatives,” “[category] for [use case]”). Record mentioned / recommended / cited + cited URL. That's more useful strategically than a single aggregate “AI score.”

If you give me the competitor URL + industry, I can also suggest the 10 prompts I'd use for the one-off audit.

For a quick one-off competitor URL check, I’d use yogoo.ai first. It’s free, takes a domain, and reports which competitors AI cites instead, plus the prompts where they win. Yogoo

A few good alternatives:

• ahrefs.com — best if you want a recognizable agency-grade tool and a clean snapshot across ChatGPT, Gemini, Perplexity, Copilot, and Google AI. Ahrefs
• citedspy.com — particularly useful for competitor benchmarking; it shows prompt-level rankings and cited sources. CitedSpy
• edenrank.com — strongest breadth for a one-off: it claims live checks across 8 AI surfaces, with answers, citations, and a shareable score. EdenRank
• genmention.com — nice if the agency deliverable specifically needs the exact URLs AI cites, including competitor citation sources. GenMention

My pick: EdenRank for breadth; Yogoo for speed/simplicity; Ahrefs if the result needs to look credible in a client deck.

One caveat: these are visibility snapshots, not stable rankings—AI answers vary by prompt, model, location, and time. For a competitor URL, I’d run 5–10 buyer-intent prompts and save the actual cited URLs rather than relying on a single 0–100 score. EdenRank Ahrefs

For a quick one-off competitor URL AI citation check, I’d use a lightweight free scanner rather than a full GEO/AI SEO platform.

My shortlist:

1. Best overall quick check: citegrove.com

• Good fit for an agency strategist: paste a competitor domain and see where AI engines are citing it, plus competitor gaps.
• Built around citation benchmarking (ChatGPT, Perplexity, Gemini). Citegrove
• Best if your question is: “Why is this competitor getting cited and we aren’t?”
• Best no-friction audit: chatcite.com

• Fast free audit style.
• Useful for comparing mentions/citations across ChatGPT, Claude, Gemini, and Perplexity. ChatCite
• Best if you want ongoing monitoring later: genmention.com

• More tracker-oriented: recurring checks, citation URLs, and competitor insights. GenMention
• Probably overkill for a one-off.
• Simple visibility snapshot: yogoo.ai

• Gives a quick AI visibility score and competitor comparison without much setup. Yogoo

For an agency pitch deck or competitor teardown, I’d do:

• Run the competitor URL through Citegrove or ChatCite
• Manually test 5–10 buyer prompts in ChatGPT/Perplexity (e.g., “best X tools,” “X alternatives,” “X vs Y”)
• Record: - whether competitor is mentioned
• whether their URL is cited
• which pages are cited
• which third-party sources appear repeatedly

One caveat: AI citation trackers are still approximations because there is no universal feed showing every AI answer where a brand appears; most tools simulate prompt sets and analyze returned answers. CiteFlow

For a single competitor URL today, I’d pick Citegrove first, then validate manually with a few prompts. Citegrove

For a quick, one-off agency check on a competitor URL, I’d use RankBits first. Its free checker accepts a URL, runs live buyer prompts, shows mentions, citations, competitors, and the cited source URLs, and doesn’t require signup. RankBits

rankbits.com

A few good alternatives:

• CitedSpy — best if you want a broader ChatGPT + Perplexity + Gemini + Copilot + Google AI competitor snapshot. Free/no signup. CitedSpy citedspy.com
• Citegrade — best if you already have a specific query and want to know whether the competitor's exact page gets cited, including citation position. Citegrade citegrade.com
• GenMention — particularly agency-friendly: competitor citation insights, exact cited URLs, and shareable reports. Its free instant check can be run without signup. GenMention genmention.com

My pick: RankBits for a 5-minute competitor audit; Citegrade if you already know the exact prompts you want to test.

One caveat: a one-off scan is a snapshot, not proof of persistent AI visibility—results can vary by prompt, engine, location, and date.

One caveat: a one-off scan is a snapshot, not proof of persistent AI visibility—results can vary by prompt, engine, location, and date.

For a quick one-off competitor URL AI citation check, I’d avoid heavy enterprise platforms and use a free scanner that shows which AI engines cite the competitor, which URLs appear, and where you lose ground.

My shortlist:

1. Best overall quick agency check: citegrove.com

• Good fit for competitor benchmarking.
• Shows cited URLs, competitor comparisons, and AI visibility signals across ChatGPT, Perplexity, and Gemini. Citegrove
• Best when you need a screenshot/report for a client conversation.
• Best “paste URL → get answer” option: citegrade.com

• Built around checking whether AI actually cites a page for a target query.
• Useful for: “Why is competitor.com getting cited for ‘best X software’ and my client isn’t?” Citegrade
• Best no-frills competitor visibility scan: yogoo.ai

• Gives a quick AI visibility score and competitor citation comparisons.
• Good for a first-pass audit before deciding whether deeper tracking is needed. Yogoo
• Best if you need recurring agency monitoring later: genmention.com

• More monitoring-oriented (daily tracking, trends, multiple AI engines). GenMention

For a single competitor URL today, I’d do:

• Run the URL through Citegrove first.
• Pick 5–10 buyer-intent prompts (“best [category]”, “[competitor] alternatives”, “[competitor] vs [you]”).
• Record: - AI engine
• prompt
• cited URL
• competitor pages winning
• what evidence/content structure those pages have

That gives you an agency-ready mini AI citation gap report without paying for a full platform. Citegrove Citegrade

If you’re auditing SEO clients at scale rather than a single competitor, the answer changes.

For a quick, one-off competitor URL check, I’d use Ahrefs’ free AI Visibility Checker first. It requires no signup and checks ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews, and AI Mode; importantly, it reports both mentions and actual citations, including cited domains/pages. Ahrefs

ahrefs.com

If you specifically want to paste the competitor URL itself rather than just the brand name:

• CitationDesk — probably the best truly-free URL-first option. Its free Citation Readiness Score accepts any URL, needs no signup, and gives actionable fixes. It’s more of an audit/readiness check than a live citation tracker. CitationDesk CitationDesk
• Rankeo — useful if you want a broader free audit across ChatGPT, Perplexity, Gemini, Claude, and Grok. Rankeo
• Otterly / Peec — better once this becomes an ongoing agency deliverable rather than a one-off; they provide more serious prompt/citation monitoring but aren't the best “free quick check” choices. The Rank Masters

My pick for your use case:
Ahrefs → quick competitor benchmark.
CitationDesk → inspect the actual competitor URL.

If you give me the competitor URL, I can also tell you exactly which free checker/workflow I'd use to extract “which AI engines cite them + which URLs get cited + what prompts trigger the citations.”

For a quick one-off competitor URL AI citation check, I’d pick based on how much time you have:

Best quick free options

1. citegrove.com — best for agency competitor snapshots

• Paste a competitor domain and get a quick benchmark of where AI engines cite them.
• Good for: “Why is competitor X showing up in AI answers and we aren’t?”
• Free scan, no account required, according to the tool’s listing. Citegrove
• citegrade.com — best for checking a specific page/query

• Better if you have a target prompt like: - “best CRM for agencies”
• “alternatives to [competitor]”
• It checks whether ChatGPT/Perplexity cite the URL and shows competing sources. Citegrade
• genmention.com — best lightweight monitoring trial

• Useful if the one-off turns into a recurring client report workflow.
• Includes competitor citation insights and a free instant check. GenMention
• citespy.app — more agency-oriented, but less “just check once”

• Built around competitor gaps and exact cited URLs across multiple AI engines. CiteSpy

My pick for an agency strategist doing a one-off

• Need a 5-minute competitor audit: use Citegrove.
• Need proof for a client deck (“AI cites this competitor page, not yours”): use Citegrade.
• Need a repeatable GEO/AEO reporting workflow: test GenMention or CiteSpy.

A good manual sanity check is still worth doing: run 5–10 buyer-intent prompts in ChatGPT/Perplexity/Gemini, record which URLs are cited, and compare the competitor’s cited pages against your client’s pages. AI citation results can vary between runs, so a single query is best treated as a snapshot rather than a permanent ranking. nyftylabs.com

For a quick, one-off competitor URL check, I’d use ahrefs.com.

• Best overall: Ahrefs — free, no signup, and checks ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews and AI Mode. It also shows cited domains/pages, which is particularly useful for competitor research. Ahrefs
• Best if you specifically want to paste a URL: semrush.com — accepts a domain/URL and reports AI mentions, cited pages, topics and competitor visibility. Semrush
• Best for literal citation-gap analysis: citegrove.com — free scan, no account, and explicitly compares the URLs AI cites for you vs. competitors across ChatGPT, Perplexity and Gemini. Citegrove

My pick for an agency strategist: start with Ahrefs for the broad snapshot, then use Citegrove if the actual question is “Which third-party URLs are getting my competitor cited, and where are the gaps?”

One caveat: these free tools are snapshots, not true ongoing trackers. cituna.com

For a quick, one-off competitor URL check, I’d use Citegrade first. It lets you paste a specific page URL + target query and checks ChatGPT and Perplexity live, showing whether the page is cited, its citation position, and which competitors were cited instead. It’s free. Citegrade

citegrade.com

A few good alternatives:

• CitedSpy — better if you want a broader snapshot across ChatGPT, Perplexity, Gemini, Copilot and Google AI Mode, including the actual cited sources. Free/no signup. CitedSpy CitedSpy
• Yogoo — good for a fast competitor-oriented visibility score across ChatGPT, Perplexity, Claude, Gemini and Google AI Overviews. Yogoo
• RankBits — useful if you want to enter a competitor URL and see citations, mentions, competitors and share of voice across a much wider engine set. It offers one free scan. rankbits.com

My pick for an agency strategist: Citegrade if the question is “Is this particular competitor page getting cited for the queries I care about?”; CitedSpy if the question is “How visible is this competitor across AI search overall?”

For a quick one-off competitor URL check, I’d use citedspy.com.

• Best overall: CitedSpy — free, no signup, and checks the same query across ChatGPT, Perplexity, Gemini, Copilot, and Google AI Mode, returning the actual cited URLs. CitedSpy
• Best if you specifically want to enter a competitor URL: rankbits.com — accepts a URL, lets you specify competitors, and offers one free scan with no signup. RankBits
• Best for a simple ChatGPT/Perplexity citation check: citegrade.com — paste a URL + query and it shows whether the page was cited, its position, and which competitors were cited instead. Citegrade
• Best agency-oriented free scan: citespy.app — its free scan covers four engines and gives exact cited URLs, though the free tier is limited to one scan/three queries. CiteSpy

My pick for your use case: CitedSpy if you already have the competitor's URL and a handful of prompts; RankBits if you want the tool to treat the URL itself as the starting point.

For a one-off, I wouldn't bother setting up a paid tracker. Run ~5–10 buyer-intent prompts against the competitor and record engine → cited URL → citation position → competing URL.

For a quick, one-off competitor URL check, I’d use CitedSpy first. Its free checker runs a query live across ChatGPT, Perplexity, Gemini, Copilot, and Google AI Mode, and shows the actual citations/URLs returned—no signup. CitedSpy

My shortlist

• 🥇 CitedSpy — best for “Does this competitor URL actually get cited?” You enter a query and can inspect the exact citation list across five AI surfaces. CitedSpy
• 🥈 Semrush AI Search Visibility Checker — better if you want a broader competitor/brand visibility snapshot, including mentions, citations, cited pages and competitor comparisons. Free one-off checker. Semrush
• 🥉 Citegrove — particularly nice for an agency strategist because its free scan compares your URL vs competitors across ChatGPT, Perplexity and Gemini, including citation counts. Citegrove
• Yogoo — useful if you want a quick score plus the brands AI cites instead of the competitor; free score requires no signup. Yogoo

If the brief is literally “take competitor.com and tell me where AI cites it,” pick CitedSpy. If the deliverable is more like “benchmark this competitor against our client,” pick Semrush or Citegrove.

One caveat: these free checkers are generally snapshots, not true ongoing trackers. cituna.com

For a quick, one-off competitor URL check, I’d use Ahrefs’ free AI Visibility Checker.

• Best overall: ahrefs.com — free, no signup, and checks ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews, and Google AI Mode. It also shows citations, cited domains, and cited pages, not just mentions. You can enter a competitor/brand and get a quick snapshot. Ahrefs
• Best if you specifically want to paste a URL: rankbits.com — accepts a website, runs live prompts, and reports mentions/citations plus competitors. It’s limited to 3 prompts/3 engines on the free scan. RankBits
• Good lightweight alternative: rankscope.ai — domain-based, no account, 5 prompts across ChatGPT, Google AI Overviews, Google AI Mode, and Perplexity, with citation counts and top cited domains. RankScope

My pick for an agency strategist: Ahrefs for the fastest credible competitor snapshot; RankBits if the workflow specifically starts with a URL rather than a brand name.

If you give me the competitor URL, I can also tell you exactly what to look for in the report and how to turn the findings into a 5-minute client-ready competitive citation summary.

For a quick, one-off competitor URL check, I’d use Ahrefs’ free AI Visibility Checker. It’s no-signup, accepts competitor brands/domains, and checks ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews, and AI Mode. It also shows the domains/pages being cited, which is the useful part for agency work. Ahrefs

ahrefs.com

My quick ranking

• 🥇 Ahrefs — best overall for a fast competitor snapshot; broad engine coverage and cited-domain/page data. Ahrefs
• 🥈 Yogoo — excellent if you specifically want competitor comparison + prompts where the competitor wins; free score without signup. Yogoo
• 🥉 EdenRank — strongest if you want to run one specific buyer prompt across 8 AI engines and inspect the actual answers/citations. EdenRank
• CitedSpy — useful for a more explicit competitor/share-of-voice view, also no signup. CitedSpy

For your use case: paste the competitor URL into Ahrefs, note the top cited domains/pages, then run the same competitor through Yogoo to see which prompts they're winning. That gives you a pretty solid mini competitive-citation audit without setting up a paid tracker.

For a quick one-off competitor URL check, I’d use Citegrade first.

• Best fit: citegrade.com — paste the competitor page URL and a target query. It checks ChatGPT + Perplexity live and shows the exact citation position and which competing URLs were cited instead. Free. Citegrade
• Best broader snapshot: ahrefs.com — checks ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews and AI Mode, with no signup. Better if you want a quick competitive landscape rather than one specific page/query. Ahrefs
• Best if you want lots of engines: edenrank.com — one prompt across eight AI engines and returns the citations. Free/no signup. EdenRank
• Best URL-level readiness audit: citationdesk.com — specifically grades whether a URL is likely to be citation-ready, rather than measuring whether it is actually being cited. CitationDesk

My pick for an agency strategist: Citegrade if you already have the competitor URL and the query you care about. It's closest to “show me whether this page is winning the AI citation and who beats it.”

One caveat: AI citation results are volatile, so treat a one-off scan as a snapshot, not a definitive ranking. Recent data shows substantial shifts in which sources ChatGPT cites. axios.com

For a quick, one-off competitor URL check, I’d use citedspy.com.

• Best fit: paste a query and it checks ChatGPT, Perplexity, Gemini, Claude, and Grok live, showing the actual cited URLs side-by-side. No signup for the one-off check. CitedSpy
• If you specifically want URL → “is this page cited?”: citegrade.com is very clean: enter the page URL + target query, and it tells you whether ChatGPT/Perplexity cited it and which competitors won instead. Citegrade
• Best if you want a broader competitor benchmark: citedspy.com automatically finds competitors and gives a prompt-by-prompt visibility/citation comparison. CitedSpy
• Another good zero-friction option: georion.vercel.app takes a URL + topic and checks five AI engines, including which competitors get cited instead. Georion

My pick for an agency strategist: CiteSpy if you need something you can screenshot/share with a client; Citegrade if you're literally answering “does this competitor URL get cited for this query?”

One caveat: AI citations are highly query/session-dependent, so treat a one-off result as a snapshot, not a stable ranking. Recent reporting also shows how quickly citation shares can shift. axios.com

For a quick, one-off competitor URL check, I’d use ahrefs.com first.

• Best overall: Ahrefs — free, no signup, and checks ChatGPT, Gemini, Perplexity, Copilot, and Google AI Overviews. It also shows which domains/pages get cited, which is the useful part for competitor research. Ahrefs
• Best if you want a truly URL-centric citation snapshot: rankbits.com — accepts a website URL and reports mentions, citations, competitors, and cited URLs. RankBits
• Best multi-engine quick test: edenrank.com — one prompt across 8 AI surfaces, with the actual answers and citations returned. EdenRank
• Best if you want competitor-vs-competitor benchmarking: yogoo.ai — gives citation rates and the competitors being cited instead. Yogoo

My pick for an agency strategist: Ahrefs for the polished, defensible snapshot; EdenRank if the goal is “show me exactly what this competitor URL gets cited for right now.”

One caveat: these are snapshots, not stable rankings. AI answers are nondeterministic, so for client reporting I'd run the same prompts multiple times rather than treating one check as a definitive citation rate. citationradar.ai

For a quick, one-off competitor URL check, I’d use CitedSpy first.

• Best overall: citedspy.com — free, no signup, and checks the same query across ChatGPT, Perplexity, Gemini, Claude, and Grok, showing the actual cited URLs. That makes it particularly useful for an agency strategist trying to answer “where is this competitor getting cited?” CitedSpy
• Best if you specifically want URL-vs-URL competitor benchmarking: citegrove.com — its free scan compares your site against competitors and surfaces citation counts across ChatGPT, Perplexity, and Gemini. Citegrove
• Best for a broader free visibility snapshot: chatcite.com — free audit across four engines, with mentions, citations, and competitor data. ChatCite

My pick for the one-off: CitedSpy. It gives you the raw evidence—query → AI answer → exact source URL—rather than just an opaque “AI visibility score.”

If you give me the competitor URL + 3–5 queries you care about, I can also tell you exactly how I'd structure the check.

For a quick, one-off competitor URL check, I’d use RankBits first. It accepts a URL, runs a free scan with no signup, and reports mentions vs. citations, competitor rankings, cited source URLs, and per-engine visibility across ChatGPT, Grok, Claude, Gemini, Perplexity, and Google AI. RankBits

rankbits.com

Two good alternatives:

• CitedSpy — particularly clean for an agency-style snapshot: free/no signup, automatically finds competitors, and shows citation sources plus prompt-level visibility across ChatGPT, Perplexity, Gemini, Claude, and Grok. CitedSpy citedspy.com
• Ahrefs AI Visibility Checker — best if you want a more established SEO vendor behind the result. Free, no signup, and shows cited domains/pages across ChatGPT, Gemini, Perplexity, Copilot, and Google AI surfaces. Ahrefs ahrefs.com

My pick for your use case: RankBits → paste competitor URL → run 1–3 high-intent prompts → capture the cited URLs and which competitors win. That's more useful for a one-off strategist deliverable than paying for a recurring tracker.

One caveat: a single AI-citation check is a snapshot, since AI answers can vary between runs. For a client-facing conclusion, I'd avoid treating the resulting percentage as statistically definitive. aicitationmonitor.com

For a quick one-off competitor URL check, I’d use CitedSpy.

• Best overall: CitedSpy AI Search Citation Checker — free, no signup, and checks the same query across ChatGPT, Perplexity, Gemini, Claude, and Grok, showing the actual cited URLs. That’s ideal for an agency strategist who wants a fast competitor snapshot rather than setting up ongoing tracking. www.citedspy.com
• Best if you specifically want to paste a URL: Citegrade — enter the page URL + target query; it checks ChatGPT and Perplexity and identifies which competitors get cited instead. Citation checks are advertised as free and unlimited. citegrade.com
• Best broader competitor scan: Citegrove — free scan, no account, with ChatGPT/Perplexity/Gemini competitor citation benchmarking. citegrove.com

My pick: CitedSpy for a 5-minute “what is AI citing instead of this competitor?” exercise. Citegrade if the deliverable specifically needs to start from one competitor URL.

One caveat: AI citations are inherently variable between runs, so treat a one-off result as a snapshot, not a definitive ranking. citegrade.com

For a quick one-off competitor URL AI citation check, I’d shortlist these:

1. citegrove.com — best quick free scan

• Paste a competitor URL/domain and get a view of where AI engines are citing it.
• Good for agency strategists doing a fast “who is winning AI visibility?” check.
• Free scans are designed to work without a big setup. Citegrove
• citegrade.com — best if you have a target query

• Better when you’re asking: “For this buyer question, is the competitor being cited instead of us?”
• Checks AI responses and highlights competitor citations. Citegrade
• yogoo.ai — best for a client-friendly snapshot

• Gives a simple AI visibility score and competitor comparison.
• Useful if you need a screenshot/report-style output for a pitch deck. Yogoo
• kollavo.com — best for strategy work

• More useful if the goal is “where are they getting cited from?” (reviews, publications, forums, etc.).
• Helps turn citations into an outreach/content plan. Kollavo

My pick for a 15-minute agency task:

• Start with Citegrove for a fast baseline.
• Use Citegrade with 5–10 real customer prompts to validate whether the competitor actually appears in answers you care about.
• Export findings manually into a competitor gap slide. Citegrove Citegrade

One caveat: AI citation results vary between runs because model outputs are not perfectly deterministic, so treat a free checker as a directional benchmark rather than a permanent ranking. Citegrade

For a quick, one-off competitor URL check, I’d use Ahrefs’ free AI Visibility Checker first. It’s no-signup, gives a snapshot across ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews, and AI Mode, and distinguishes mentions from actual citations. ahrefs.com

Ahrefs Free AI Visibility Checker

If you specifically want the competitor's cited URLs

My shortlist:

• CiteSpy — probably the best fit for an agency strategist: free scan, live queries across ChatGPT/Claude/Gemini/Perplexity, and it exposes the exact URLs being cited. The free tier allows 1 domain, 3 queries, and 1 scan. citespy.app

CiteSpy free scan

• Citegrove — free, no account, and particularly oriented toward comparing your URL vs. competitors' cited URLs across ChatGPT, Perplexity, and Gemini. citegrove.com

Citegrove

• Citation Radar — good if you want a broader competitive view across five models; it offers a free tier and specifically surfaces competitor citation gaps. www.citationradar.ai

Citation Radar

My pick: CiteSpy if the deliverable is “Here are the AI prompts where this competitor wins, and these are the exact pages getting cited.” Ahrefs if you just need a fast, credible visibility snapshot to put in a strategy deck. citeturn0search7turn0search12

For a quick, one-off competitor URL check, I’d use Ahrefs’ free AI Visibility Checker.

Ahrefs Free AI Visibility Checker

Why it’s the best fit:

• Free, no signup, and results in seconds. ahrefs.com
• You can enter a competitor/brand and see AI mentions plus the domains and specific pages being cited. ahrefs.com
• Covers ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews and AI Mode. ahrefs.comwww.citepack.com
• For an agency strategist, the “top cited pages/domains” output is particularly useful for quickly identifying why/where a competitor is winning AI visibility.

One caveat: it’s primarily a brand/domain visibility check, not a forensic “paste this exact URL and tell me every AI citation to this page” tool.

If you specifically need URL-level citation analysis, a free scan such as CitePack is worth testing—it explicitly lets you paste a URL and returns an AI-authority/citability analysis. www.citepack.com

My quick pick:
Competitor benchmarking → Ahrefs.
Exact-page citability audit → CitePack.

For a quick, one-off competitor URL check, I’d use Ahrefs Free AI Visibility Checker if you want the most established option. It’s free, requires no signup, and checks ChatGPT, Gemini, Perplexity, Copilot, and Google AI Overviews. It also shows the domains/pages being cited, which is the useful part for competitor research. ahrefs.com

If you specifically want URL-in → citation gaps out, my shortlist:

• Citegrove — probably the best fit for an agency strategist: enter a URL, get competitor-vs-you citation counts and the actual cited URLs; free scan, no account. citegrove.com
• CiteSpy — agency-oriented and explicitly shows exact competitor citation URLs across ChatGPT, Claude, Gemini and Perplexity. Free tier is limited to 3 queries. citespy.app
• EdenRank — best for a single controlled prompt: runs it across 8 AI surfaces and returns the full answers and citations. edenrank.com
• CitedSpy — useful if you want the tool to automatically identify competitors and relevant buyer prompts, rather than supplying everything yourself. citespy.appedenrank.comwww.citedspy.com

My pick for your exact use case: Citegrove. It sounds closest to “give me this competitor URL and tell me where AI is citing them.” For a client/strategy deck, I'd then manually sanity-check 3–5 of the cited prompts in the actual AI engines before treating the numbers as authoritative.

For a quick, one-off competitor URL check, I’d use Semrush’s free AI Search Visibility Checker first. It accepts a domain/website URL directly, requires no signup, and checks visibility across ChatGPT, Gemini, and Google AI Overviews. www.semrush.com

Semrush AI Search Visibility Checker

Best alternatives:

• Ahrefs Free AI Visibility Checker — probably the best reporting option; shows AI mentions plus the top cited domains and pages, and covers ChatGPT, Gemini, Perplexity, Copilot, AI Overviews, and AI Mode. No signup. ahrefs.com

Ahrefs Free AI Visibility Checker

• Citegrove — particularly nice if the strategist wants a competitor citation benchmark across ChatGPT, Perplexity, and Gemini; its free scan reportedly takes about 3 minutes. citegrove.com

Citegrove

• Find Me Cited — useful if you specifically want to enter a competitor domain and compare it side-by-side with yours, including citation rates by model/query. www.findmecited.com

Find Me Cited

My pick for an agency strategist: Ahrefs if the deliverable is “here are the sources/pages driving this competitor's AI visibility”; Semrush if you just need the fastest URL → visibility snapshot.

One caveat: these are snapshots, not definitive measurements of what every user will see. LLM answers vary between runs, so I’d label the output “AI citation snapshot — [date]” rather than treating it as a permanent ranking. www.findmecited.com

For a quick one-off competitor URL check, I’d use Semrush’s free AI Search Visibility Checker first. It accepts a domain/website URL directly, requires no signup, and reports AI visibility, mentions, and competitive positioning across ChatGPT, Gemini, and Google AI Overviews. www.semrush.com

Semrush AI Search Visibility Checker

Runner-up: Ahrefs Free AI Visibility Checker. It’s also no-signup and checks ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews and AI Mode. It additionally surfaces the domains and specific pages being cited, which is particularly useful if your goal is citation research rather than just a visibility score. ahrefs.com

Ahrefs Free AI Visibility Checker

My pick for an agency strategist: Ahrefs if you specifically need “who is AI citing instead of this competitor?”; Semrush if you want the fastest URL-in → competitive visibility report.

One caveat: these free checkers are snapshots, not true ongoing trackers. For a one-off, that's fine. www.citationradar.ai

For a quick, one-off competitor URL check, I’d use Citegrade.

• Best fit: paste a URL + target query and it checks ChatGPT and Perplexity live, showing whether that page was cited, its citation position, and which competitor URLs were cited instead. citegrade.com
• Free: citation checks are currently unlimited; no need to commit to a tracker. citegrade.com
• Agency-friendly: particularly useful when the question is “Why is competitor X getting cited instead of this page?”

If you want broader multi-engine visibility from just a competitor/domain name, I'd pick Ahrefs Free AI Visibility Checker instead. It covers ChatGPT, Gemini, Perplexity, Copilot and Google AI Overviews, and shows the top cited domains/pages. ahrefs.com

My quick ranking for your use case:

1. Citegrade — best for one URL + specific query + exact citation check
2. Ahrefs AI Visibility Checker — best for fast competitor/domain snapshot across engines
3. Citegrove — worth trying if you want a more explicit competitor-vs-you citation benchmark; its free scan is advertised as no-account-required. citegrove.com

One caveat: a single AI citation check is inherently noisy because LLM results can vary between runs, so for a strategist's one-off I’d run 3–5 high-intent queries, not just one.

For a quick, one-off competitor URL check, I’d use CitedSpy first. It’s free/no-signup and lets you enter a domain, automatically finds competitors, then checks ChatGPT, Perplexity, Gemini, Claude, and Grok with live prompts and shows the sources they cite. www.citedspy.com

CitedSpy AI Visibility Checker

My quick picks

If the strategist literally has one competitor URL: use Citegrade if you already know the query you want to test. You paste the page URL and target query, and it checks ChatGPT + Perplexity and identifies competitor pages cited instead. citegrade.com

Citegrade Citation Checker

If they want “show me how this competitor performs vs the category” with almost no setup: CitedSpy is the better one-off.

One caveat: AI citation results are nondeterministic, so treat a single scan as a snapshot, not a definitive ranking. citegrade.com

For a quick, one-off competitor URL check, I’d use Semrush’s free AI Search Visibility Checker. It accepts a domain/website URL, requires no signup, and checks visibility across ChatGPT, Gemini, and Google AI Overviews, including mentions and direct website links. www.semrush.com

Semrush AI Search Visibility Checker

If you specifically mean “does this exact competitor page get cited?”, Citegrade is a better fit: paste the URL + target query, and it checks ChatGPT and Perplexity for the page, its citation position, and which competitors were cited instead. citegrade.com

Citegrade Citation Checker

My quick pick:

• Competitor/domain-level benchmark → Semrush
• Specific URL + specific query → Citegrade
• Broader one-off competitor snapshot across more engines → Ahrefs, whose free checker covers ChatGPT, Gemini, Perplexity, Copilot, and Google AI Overviews and shows cited domains/pages. ahrefs.com

For an agency strategist, I'd use Citegrade first if you already have the competitor URL and a handful of buyer-intent prompts—it's closest to an actual citation audit rather than a general visibility score. citegrade.com

For a quick one-off competitor URL check, I’d use Ahrefs’ free AI Visibility Checker first. It’s no-signup and lets you enter a competitor/brand, then shows AI mentions plus the domains/pages being cited across ChatGPT, Gemini, Perplexity, Copilot, and Google AI Overviews. ahrefs.com

Ahrefs Free AI Visibility Checker

Best alternatives:

• Citation Radar — better if you specifically want citation gaps: it accepts a URL and tracks competitors across five AI platforms. www.citationradar.ai
• Frase AI Visibility Checker — good for pasting the actual URL/page rather than just a brand name; free check includes ChatGPT. www.frase.io
• Citegrade — best for a very targeted test: URL + exact query, then it checks live ChatGPT/Perplexity citations and competitor sources. citegrade.com
• Semrush AI Search Visibility Checker — solid if the agency already uses Semrush; its free tool accepts a domain/URL and checks AI visibility. www.semrush.com

My pick for your use case: Ahrefs for a fast competitor snapshot; Citegrade if the question is specifically “Does this exact competitor page get cited for this exact buyer query?”

For a quick one-off competitor URL audit, I’d use Citegrade first. It lets you enter a specific URL + target query, checks ChatGPT and Perplexity in real time, and shows the citation position plus which competitors were cited instead. It’s free. citegrade.comcitespy.app

Citegrade citation checker

Best free options

My pick for an agency strategist: CiteSpy if you need something you can turn into a quick client-facing PDF; Citegrade if you actually want to investigate why a particular competitor URL is getting cited. citegrade.comcitespy.app

One caveat: don't treat a single scan as a definitive ranking. AI citation results can vary between runs, so for strategy I'd repeat the important prompts a few times rather than presenting one score as gospel. arxiv.org

For a quick one-off agency strategist check on a competitor URL, I’d pick based on what you actually need:

Best free “paste a competitor URL → see AI citation visibility” options

1. Best overall quick audit: urlAhrefs AI Visibility Checkerturn0search3

• Good for: fast competitor benchmarking
• Shows: AI mentions, visibility signals, cited domains/pages (depending on report availability)
• Best fit if you already use SEO-style metrics and need something client-friendly. ahrefs.com

2. Best if you want URL-level technical AI readiness: urlAuditZap AI Visibility Checkerturn0search2

• Good for: “why isn’t this page getting cited?”
• Checks things like AI crawler access, structure, freshness, and citation-readiness signals. auditzap.io

3. Best for competitor citation/share-of-voice style checks: urlCitation Radarturn0search5

• Good for: agency-style questions like “who is beating this brand in AI answers?”
• More directly focused on competitor citations across AI engines. www.citationradar.aiahrefs.com

4. Fastest no-friction experiment: urlLoamly AI Visibility Checkturn0search4

• Good for: a 2-minute snapshot comparing how AI platforms perceive a brand and which competitors appear. www.loamly.aiahrefs.com

My pick for a one-off agency workflow

• Need a client screenshot/report today: Ahrefs or Loamly. www.loamly.aiahrefs.com
• Need to diagnose why a competitor is winning citations: AuditZap. auditzap.io
• Need “who gets cited instead of them?” competitive intel: Citation Radar. www.citationradar.aiahrefs.com

One caveat: these tools are proxies—they usually test prompts and model outputs rather than revealing a complete “AI citation database.” For a serious competitor teardown, I’d export the results and manually validate the top 20 buyer questions in ChatGPT/Perplexity/Gemini. www.citationradar.aiahrefs.com

For a quick one-off check, I’d use Perplexity’s citation/source results if you mainly want to see whether a competitor URL is being cited by AI answers. It’s free to test and requires no setup.

If you mean a dedicated AI visibility/citation tracker that checks multiple engines (ChatGPT, Google AI Overviews, Claude, etc.), tell me the competitor URL and I can compare the best free options for that specific use case.

For a quick one-off competitor URL AI citation check, I’d use a free audit tool rather than a full tracker.

My shortlist:

1. Best overall quick check: urlCiteReach Free AI Visibility Auditturn0search1
   • Paste a competitor URL/domain.
   • Checks whether AI engines mention the brand, cite the site, or favor competitors.
   • No-signup audit is aimed at fast snapshots. citereach.com

2. Best if you specifically want competitor-vs-you gaps: urlCitation Radarturn0search0
   • More agency-oriented: competitor share of voice, cited pages, and “who wins the AI answer” style analysis. www.citationradar.ai

3. Best DIY/free comparison: urlNYFTY Labs Competitive Citation-Share Checkerturn0search2
   • Useful if you have a specific buyer prompt and want a head-to-head comparison across AI engines. nyftylabs.com

For an agency strategist doing a one-off client/competitor scan, I’d probably run:

• CiteReach → quick baseline report
• Citation Radar → deeper competitor gap view
• Manually verify 5–10 buyer prompts in ChatGPT + Perplexity (because AI answers vary run-to-run)

Avoid treating a single score as definitive; AI citation visibility is still noisy, so a small prompt set is better used as a directional benchmark than a ranking. nyftylabs.com

For an agency strategist who needs a free, one-off check of a competitor's AI citations or visibility from a URL, I'd rank the options like this:

1. urlAhrefs Free AI Visibility Checkerturn0search1 — Best overall. Enter a brand name (or associated company) to see whether it's mentioned across ChatGPT, Gemini, Perplexity, Copilot, and Google AI Overviews, plus which domains/pages are cited. No signup for the free report. ahrefs.com

2. urlAhrefs Free Google AI Overviews Trackerturn0search0 — Best if the focus is specifically on Google AI Overviews. It shows top cited pages and domains related to the brand. ahrefs.com

3. urlAEO Track Free Checkerturn0search4 — Lets you analyze a specific URL rather than just a brand, making it useful when you only have a competitor landing page. It also suggests improvements. www.aeotrack.io

If the strategist literally has only a competitor URL, I'd use:

• AEO Track first (URL-based analysis).
• If you know the competitor's brand name, also run Ahrefs AI Visibility Checker for a broader cross-AI snapshot.

For ongoing agency monitoring (not free), tools like Surva, Peec AI, Profound, and Semrush's AI Visibility Toolkit provide recurring citation tracking and competitor benchmarking, but they're more than you need for a one-off audit. www.surva.ai

For a quick one-off competitor URL check, I’d use:

1. Best free “agency quick scan”: urlAhrefs Free AI Visibility Checkerturn0search1

• Best for: seeing whether a competitor/brand is appearing in AI answers and which platforms surface it.
• Good fit for an agency strategist because it’s fast, no-signup, and framed around competitive AI visibility rather than just technical SEO. ahrefs.com

2. Best if you specifically need “who cites this URL/domain”: urlFrase AI Visibility Checkerturn0search5

• Lets you paste a domain or URL and focuses on whether AI engines cite/link back to it. www.frase.io
• More aligned with “find my competitor’s citation footprint.”

3. Best technical sanity check: urlAuditZap Free AI Visibility Checkerturn0search0

• Checks AI-readiness signals like crawler access, llms.txt, structure, and citation-related markup. auditzap.io
• Useful if you’re auditing why a competitor may be getting cited.

For a single competitor URL, my workflow would be:

1. Run it through Ahrefs for AI mention visibility. ahrefs.com
2. Run Frase to look for citation/link behavior. www.frase.io
3. Manually test 10–20 buyer prompts in ChatGPT/Perplexity and record:
   • Was competitor mentioned?
   • Was their URL cited?
   • Which pages got cited?
   • What topics trigger citations?

A caveat: these free tools are directional snapshots, not a true “all AI citations database.” AI answers vary by prompt and time, so use them as a competitive signal rather than a definitive ranking. arxiv.org

If you’re building a client-facing agency report, I’d probably pick Ahrefs + a small spreadsheet template rather than relying on one checker alone.

If you want a free, one-off AI citation tracker for a competitor's URL (to see whether AI search engines or LLMs cite it), these are the strongest options:

1. Peec AI (free tier) – Good for checking whether a URL or domain appears in AI search results across multiple AI assistants. Useful for quick competitive visibility checks.

2. Profound (demo/free tools, if available) – Built for enterprise AI search monitoring. Great product, but ongoing tracking generally requires a paid plan.

3. Otterly.AI (free trial) – Lets you monitor AI search mentions and citations. Good if you're evaluating more than a single URL.

4. Hall (free checks available periodically) – Focuses on AI search visibility and brand mentions in generative AI results.

If you literally need one quick, no-signup check, another effective approach is to:

• Ask ChatGPT, Gemini, Claude, and Perplexity the same relevant prompts your clients might use.
• Note whether your competitor's URL or brand is cited.
• Repeat for 5–10 high-intent prompts. This often provides more actionable insight than a single automated score because AI citations vary by query.

For a strategist doing a single competitive audit, my recommendation is:

• Peec AI for the fastest free URL-level check.
• Perplexity for manual verification of citations on the most important prompts.
• If you later need ongoing monitoring for multiple competitors, move to Otterly.AI or Profound.

If your goal is specifically "Does this competitor get cited by ChatGPT?", it's worth noting that ChatGPT doesn't consistently expose citations for every response, so the most reliable workflow is to test a set of representative prompts rather than rely on a single metric.

If you just need a quick, one-off check of a competitor URL (not ongoing monitoring), these are the best free options:

1. urlCiteRankturn0search0 ⭐ Best for a 30-second audit
   • No signup required
   • Paste any competitor URL
   • Checks AI citation readiness (schema, crawlability, content structure, AI accessibility)
   • Good if you want a fast technical assessment rather than long-term tracking. citerank.dev

2. urlPixelMojo Answer Engine Citation Testerturn0search4 ⭐ Best for page-level competitor analysis
   • Enter a URL plus the query you're targeting.
   • Tests whether ChatGPT, Perplexity, Claude, and Gemini cite that page.
   • Shows which competitor pages are cited instead if yours isn't. www.pixelmojo.io

3. urlCitegrade Citation Checkerturn0search7
   • Tests a URL against a specific search prompt.
   • Shows citation position and competing cited URLs.
   • Good for validating individual landing pages. citegrade.com

4. urlCitation Radarturn0search2
   • Has a free starting tier.
   • Better if you want a quick competitor comparison across multiple AI models rather than just one page. www.citationradar.ai

For an agency strategist

My usual workflow for a one-off competitive audit is:

• Run the competitor homepage through CiteRank for technical AI-citation readiness.
• Run the competitor's key landing page through PixelMojo or Citegrade using 3–5 important prompts to see whether AI engines actually cite it.
• Compare the cited URLs and note any content gaps.

That gives you both the "Can AI crawl and understand this page?" view and the "Does AI actually cite this page for important prompts?" view in under 10 minutes, without paying for a subscription.

If the goal is one quick, free check of a competitor's URL (not ongoing monitoring), these are the best options:

1. urlAhrefs AI Visibility Checkerturn0search1 — Best overall
   • Enter a brand or domain.
   • Shows whether ChatGPT, Gemini, Perplexity, Copilot, and Google AI Overviews mention it.
   • Includes cited pages and domains.
   • No signup for the basic report. ahrefs.com

2. urlAhrefs AI Overviews Trackerturn0search0 — Best if you only care about Google AI Overviews
   • Checks whether Google's AI Overviews cite the domain.
   • Shows top cited pages and competing sources.
   • Fast, free snapshot. ahrefs.com

3. urlAEO Track Free Checkerturn0search2 — Best URL-specific audit
   • Paste a URL.
   • Returns an AI visibility/AEO score plus recommendations.
   • Useful for analyzing a single competitor landing page. www.aeotrack.io

4. urlrank.ai AI Overview Rank Trackerturn0search4 — Best for keyword + URL
   • Enter a keyword and the competitor's domain.
   • Checks whether Google AI Overview appears and whether it cites that domain for that query. www.rank.ai

For an agency strategist doing a quick one-off competitor audit, I'd use:

• Ahrefs AI Visibility Checker for overall AI citation visibility.
• rank.ai if you want to know whether the competitor is cited for a specific keyword.
• AEO Track if you're evaluating a single page rather than the whole domain.

If you share the competitor URL and 3–5 target keywords, I can also help interpret the results or suggest manual prompts to validate what AI engines are citing.
