AI SEO Keyword Cluster Generator
This free AI SEO keyword cluster generator groups a pasted list of keywords into topic clusters by meaning and search intent, and suggests one page for each cluster. Paste up to 200 keywords, one per line, and get named clusters with their intent and a suggested page title. It helps plan site structure and avoid keyword cannibalisation.

About this tool
The generator asks Claude, an AI model, to group keywords that a single page could satisfy, label each group by intent (informational, commercial, transactional or navigational) and propose a page for it. Close variations such as plurals and word-order swaps land in the same cluster.
Paste your keywords, one per line, optionally name your site type, and run it. Review the clusters: move any keyword that clearly belongs elsewhere, and merge clusters that your site would answer on one page. Then use the blog outline generator for each page.
The list is limited to 6,000 characters, around 200 keywords. The AI has no search volume, difficulty or live results, so clusters are based on meaning, not on what Google shows. Check the real results for each cluster's main keyword to confirm the intent. The output is AI-generated, so treat it as a first grouping and verify it before you restructure a site.
Frequently asked questions
Does it use search volume or SERP data?
No. It groups by meaning and likely intent only. Check the top results for each cluster's main keyword to confirm that the same page type ranks for all of them, and use a keyword tool for volume and difficulty.
How many keywords can I paste?
Up to about 200 keywords, or 6,000 characters, per run. For a larger list, split it by theme and run each part, then merge clusters that overlap.
How much text can I use, and are there limits?
Each run accepts up to 6,000 characters for the keyword list. There is also a fair-use limit on AI runs per visitor each day so the tool stays free. When you reach it, the free tools that do not use AI still work, and you can run this one again the next day.
How accurate is the AI output?
No AI output is guaranteed accurate. This tool can misread your meaning, repeat a common phrase or state a detail you did not give it, so read the clusters through, check every name, number and claim, and edit it before you publish. Treat it as a fast first draft that you review, not finished copy.
