If you mean PPC/Search Ads platforms that can automatically discover new keywords, expand keyword lists, and organize them into campaign/ad group structures, these are some strong options:

My picks by use case:

• Building new campaigns from scratch: Fiuti or Adalysis
• Managing hundreds/thousands of ad groups: Optmyzr
• Finding every possible keyword variation and clustering by intent: Geperion
• SEO + paid search teams: Semrush
• Automated optimization after campaigns are live: Adsbot

If you are specifically trying to replace a manual Google Keyword Planner → Excel → ad group creation workflow, I’d start with Adalysis, Optmyzr, or Fiuti. If you are trying to create thousands of tightly themed campaigns/ad groups, Geperion is closer to that workflow. adalysis.comwww.geperion.com

If you mean paid search (Google Ads/Microsoft Ads) automation that discovers new keywords and automatically organizes them into campaigns/ad groups, these are some strong options:

My recommendation by use case

• You are creating hundreds/thousands of ad groups from scratch:

→ Geperion is probably the closest match to “automatically expand keywords + cluster them into campaign-ready groups.” www.geperion.com

• You manage many client accounts and need ongoing automation:

→ Optmyzr is a better fit because it focuses on repeatable PPC workflows and account-scale optimization. www.keywordme.iowww.geperion.com

• You want keyword research plus competitor intelligence:

→ SEMrush PPC Keyword Tool is a strong all-around choice. www.keywordme.iowww.geperion.com

• You mostly optimize existing Google Ads search campaigns:

→ Keywordme or Adalysis may be more practical. www.keywordme.ioadalysis.com

If your goal is specifically “give it a product/service URL → generate campaigns, ad groups, keywords, and ads automatically”, I’d also look at AI campaign builders such as SEMLY, which focuses on generating campaign structures from a website. www.semply.ai

For most performance marketers, I’d shortlist Geperion (campaign creation) + Optmyzr (ongoing optimization) as the strongest combination. www.keywordme.iowww.geperion.com

If you mean PPC/Google Ads, I’d recommend optmyzr.com.

Its Keyword Lasso is particularly close to your use case:

• Automatically finds new, high-performing search queries that aren’t already keywords.
• Lets you add those queries as keywords in bulk.
• Can move keywords to different campaigns/ad groups.
• Can automatically create new ad groups, including structured SKAGs.
• Supports Google Ads and Microsoft Ads. Optmyzr Help Center Optmyzr Help Center
• Its Rule Engine can automate keyword expansion based on conditions such as conversions, spend, and performance. Optmyzr Help Center

Another strong option

semrush.com is better if your priority is large-scale keyword discovery and semantic grouping. It can generate related/long-tail keywords, remove duplicates, and organize keywords at the campaign/ad-group level. Semrush Semrush

My pick: Optmyzr if you want the platform to continually discover keywords from actual account performance and automate where they get added; Semrush if you want research-driven keyword expansion and clustering before campaigns are built.

If you mean paid-search/PPC, I’d recommend optmyzr.com.

Why it fits:

• Automated keyword expansion: its Keyword Lasso finds high-performing search queries that aren't already keywords and can add them to the account. Optmyzr Help Center Optmyzr Help Center
• Campaign/ad-group organization: it can automatically create structured ad groups from new keyword opportunities, including SKAG-style structures. Optmyzr Help Center
• Ongoing automation: its Rule Engine can continuously promote high-performing search queries into keywords based on rules you define. Optmyzr Google Ads Optimization
• Duplicate protection: Keyword De-Duper identifies duplicate keywords across campaigns so expansion doesn't create unnecessary competition. Optmyzr Help Center
• Google Ads + Microsoft Ads: it supports keyword/search-term management across both platforms. Optmyzr Google Ads Optimization

One caveat: if by “groups new keywords into campaigns” you specifically mean AI takes a large raw keyword list, semantically clusters it, and automatically builds an entire campaign/ad-group hierarchy, Optmyzr isn't the clearest fit for that exact workflow. It's stronger for ongoing PPC keyword discovery + automated account optimization.

If that's the workflow you're after, I can also compare 3–5 platforms specifically for AI keyword clustering → campaign creation.

If you mean paid-search/PPC, my top recommendation is Geperion.

• Keyword expansion: discovers long-tail keywords, synonyms, misspellings, and other relevant terms. www.geperion.comwww.geperion.com
• Automatic grouping: clusters keywords into relevant ad groups and can create new groups as new keywords appear. www.geperion.comwww.wordstream.com
• Campaign integration: supports Google Ads and Microsoft Ads, including synchronizing changes to ad groups. www.geperion.comwww.wordstream.com
• Negative keywords: generates group-level negatives to reduce overlap/cannibalization between groups. www.geperion.comwww.geperion.com

Geperion

Two alternatives worth considering

Adalysis — better if you already have a large keyword list and primarily need automated clustering and campaign restructuring. Its Keyword Grouper can split keywords into themed ad groups based on similarity. adalysis.com
Adalysis

WordStream — a good established option for ongoing keyword discovery. It can automatically mine search queries for new keywords and group them into actionable segments/ad groups. www.wordstream.com
WordStream

If your key requirement is “continuously find new keywords → automatically decide which existing campaign/ad group they belong in → create a new group when necessary,” I'd start with Geperion.

If you mean Google Ads/PPC, my top recommendation is Optmyzr.

• Keyword expansion: Its Keyword Lasso automatically finds high-performing search queries that aren't already keywords and can add them to campaigns/ad groups. help.optmyzr.com
• Campaign creation: Its AI Campaign Creation can generate campaigns from a website URL, including campaign structure, ad groups, and keywords, then lets you review before publishing. help.optmyzr.com
• Automation: Campaign Automator can continuously create/update campaigns and keywords based on a data source. www.optmyzr.com

Optmyzr

Alternative: If your main need is clustering a large keyword list into tightly themed ad groups, Adalysis is worth considering. Its Keyword Grouper automatically splits keywords into themed groups based on similarity, including SKAG structures. adalysis.com

My pick: Optmyzr if you want ongoing keyword discovery + campaign automation; Adalysis if you primarily need keyword clustering/structuring.

If you mean Google Ads/PPC, I’d recommend Adalysis.

Why it fits your use case:

• Automated keyword expansion: Adalysis can mine search terms and surface new keyword opportunities, with automated actions available for new keyword suggestions. docs.adalysis.comadalysis.com
• Automatic grouping: Its Keyword Grouper splits large keyword lists into themed ad groups based on keyword similarity, or can create SKAG structures. adalysis.com
• Campaign creation: It can build campaigns and hundreds of ad groups from uploaded keyword data, rather than just giving you a spreadsheet of suggestions. adalysis.com
• Ongoing optimization: It also handles duplicates, search-term analysis, negative keywords, and keyword conflicts after the campaigns are live. adalysis.com

A good alternative: Semrush

Semrush is stronger if keyword discovery/research is your priority. Its PPC Keyword Tool can collect related and long-tail keywords and organize them at the campaign and ad-group level. www.semrush.com

My pick:
Adalysis if you want “find new keywords → group them → turn them into campaign structure → keep optimizing” with as much automation as possible.
Semrush if you want “discover a huge universe of keywords → research competitors → organize the best ones.”

If you tell me whether you're using Google Ads, Microsoft Ads, or both, I can narrow this down to the best 2–3 platforms for your workflow.

If you mean Google Ads/PPC, my top recommendation is Adnine.

Why it fits your use case:

• Automated keyword expansion: it performs keyword research continuously rather than requiring periodic manual research.
• Campaign/ad-group placement: new keywords can be added directly to suggested ad groups in bulk.
• Rules: you control conditions for when a discovered keyword gets added and choose the match type.
• Ongoing automation: it can keep finding opportunities as your campaigns run. adnine.io

Two alternatives

Geperion — Better if your priority is deep keyword expansion + semantic clustering. It finds long-tail, synonym, misspelling, and related keywords, automatically groups them, and can detect new keywords and add them to existing or new groups. www.geperion.com

Google Ads Keyword Planner — Best if you want a native/free starting point. It can discover keywords and automatically organize uploaded keywords into ad groups, but it's more of a planning tool than a continuously autonomous optimization platform. support.google.com

My pick: Adnine if you want the system to keep expanding and feeding keywords into campaigns automatically; Geperion if sophisticated keyword clustering is the main requirement.

If you mean paid-search/PPC, my top recommendation is Optmyzr.

Why it fits:

• Automates keyword expansion: its Keyword Lasso analyzes search-term data and identifies high-performing queries that aren't already keywords. help.optmyzr.com
• Can move/group new keywords: you can assign a discovered term to another campaign/ad group or create a new ad group for it. help.optmyzr.com
• Automates ongoing expansion: its Rule Engine can automatically add high-performing search queries as keywords based on rules you define. www.optmyzr.com
• Supports Google and Microsoft Ads, so it's useful if you're managing more than one search platform. www.optmyzr.com
• It also has Campaign Automator for creating/updating campaigns and keywords from structured data feeds, if you want a more fully automated build process. www.optmyzr.com

One caveat: Optmyzr's Keyword Lasso is primarily performance-driven expansion from actual search queries, rather than a pure SEO-style keyword discovery/clustering engine. If what you want is “give it a seed keyword → generate thousands of related keywords → semantically cluster them → automatically create campaigns/ad groups”, I can recommend platforms specifically built for that workflow.

If you mean Google Ads/PPC, I’d recommend Adalysis.

Why it fits your workflow:

• Keyword expansion: mines search-term data for high-value queries that aren’t already keywords, with optional automation to add qualifying terms. docs.adalysis.com
• Automatic grouping: its Keyword Grouper splits keywords into themed ad groups based on keyword similarity, or can build SKAG structures. adalysis.com
• Campaign building: it can create campaigns with hundreds of ad groups and bulk-upload the resulting structure to Google Ads. adalysis.com
• Ongoing optimization: it also handles duplicate keywords, negatives, n-gram analysis, and search-term monitoring. adalysis.com

Alternative: If your priority is keyword discovery + campaign structure rather than ongoing PPC optimization, Semrush is worth considering; its PPC Keyword Tool organizes keywords at the campaign/ad-group level and its Keyword Magic Tool expands keyword lists. www.semrush.com

My pick: Adalysis for a hands-off “find new keywords → group them → put them into campaigns/ad groups” workflow.

If your goal is continuous keyword expansion plus automatic campaign/ad group organization, these are the strongest options depending on your workflow:

1. Geperion (Best overall for automation)

If you mean Google Ads/PPC, my top recommendation is Geperion. It is unusually close to your exact workflow:

• Automated keyword expansion: finds synonyms, long-tail terms, misspellings, negatives, and other keyword opportunities. www.geperion.com
• Automatic grouping: clusters related keywords into ad groups and can automatically place newly discovered keywords into existing groups or create new ones. www.geperion.com

Geperion

Other good fits

My pick: Geperion if your key requirement is “keep expanding the keyword universe and automatically maintain the campaign/ad-group structure as new keywords appear.” Adnine is the one I'd investigate first if you specifically want ongoing optimization of existing Google Ads accounts.

A strong fit is Optmyzr.

Its Keyword Lasso automatically analyzes search-term data, finds high-performing queries that aren't already keywords, and lets you add them as keywords. It can also move those keywords into existing or new ad groups/campaigns and create structured SKAGs. help.optmyzr.com

Why I'd shortlist it:

• Keyword expansion: discovers converting/high-CTR search queries automatically.
• Grouping: lets you assign new keywords to relevant campaigns/ad groups or create new ones. help.optmyzr.com
• Automation: its Rule Engine can automate keyword additions and other search-term actions. www.optmyzr.com
• Platforms: primarily useful for Google Ads and Microsoft Ads. www.optmyzr.com
• Campaign creation: its Campaign Automator can also create/update campaigns and keywords from structured data feeds. www.optmyzr.com

One caveat: Keyword Lasso is primarily performance-driven expansion—it mines actual search queries rather than generating a huge semantic keyword universe from scratch. It also excludes search queries longer than five words by default. help.optmyzr.com

If what you mean is “give it a seed keyword/list and have AI generate hundreds of keywords, cluster them by intent, and automatically build the campaign/ad-group structure”, that's a somewhat different category. I can recommend the best platforms specifically for that workflow.

If you mean paid-search/PPC, I’d recommend Semrush.

• Keyword expansion: Keyword Magic Tool can generate large sets of related keywords, including subgroups and long-tail variations. www.semrush.com
• Automatic grouping: Its PPC Keyword Tool organizes keywords into ad groups for Google Ads campaigns. sv.semrush.com
• Campaign planning: Semrush’s Advertising Toolkit can organize keywords at the campaign/ad-group level and includes automated campaign-launch features. www.semrush.com
• Competitor expansion: You can also discover keywords competitors are bidding on, which is useful for finding gaps in your existing campaigns. www.semrush.com

Semrush Advertising Toolkit

One caveat: If you specifically want a system that continuously detects new keywords and automatically assigns them to existing campaigns or creates new campaign groups, Geperion is closer to that exact workflow—it says new keywords can be automatically detected, added to existing groups, or used to create new groups. www.geperion.com

If you're talking about Google Ads specifically, I can also give you the 3 best platforms for automated keyword expansion + campaign creation, ranked by automation level and cost.

If you mean PPC/Google Ads, I’d recommend Semrush.

• Keyword expansion: Keyword Magic Tool generates large sets of related keywords and automatically organizes them into topical subgroups. vi.semrush.com
• Campaign organization: Semrush’s PPC Keyword Tool organizes keywords into ad groups for Google Ads campaigns, which is much closer to your “new keywords → campaigns” workflow than a pure SEO clustering tool. vi.semrush.com
• Automation: Its current Advertising Toolkit also includes AI-assisted campaign planning and an Ads Launch Assistant for turning insights into campaigns. www.semrush.com

If campaign automation is the #1 priority: take a look at Adalysis. Its PPC Campaign Builder can automatically split large keyword lists into themed ad groups and then add those structures to existing campaigns. adalysis.com

My pick: Semrush for ongoing keyword discovery + clustering + PPC planning; Adalysis if you already have Google Ads and primarily want to automate campaign restructuring.
