Free keyword clustering tool
Paste a list of search queries — AI groups them into semantic clusters (one cluster = one page). Identifies intent for each group. 5 to 100 queries at a time, no signup.
How to use the output
- 1Each cluster is a candidate for a separate page (article, category, landing).
- 2Within one page, optimize text for all queries in the cluster. Main query → H1, others → subheadings and body.
- 3Don't try to rank one page across different intents — it hurts CTR. If a cluster is 'mixed', consider splitting.
- 4Use the cluster intent to pick format: commercial → category/comparison, informational → how-to article, transactional → landing with CTA.
Limits. Between 5 and 100 phrases per run, each up to 200 characters. 10 groupings per day per device. Sign in for higher limits: 10 / 50 / 150 / 500 depending on your plan.

- What is keyword clustering?
- It’s grouping the queries that a single page can cover. Each cluster is one future page on your site.
- What method does this tool use?
- Semantic, by meaning via AI — without parsing the SERP. It’s fast and free; recheck borderline commercial clusters against the top results afterwards.
- Why group queries at all?
- So you don’t build a separate page for every keyword. Otherwise pages compete with each other and sink — that’s called cannibalization.
