Keyword Cluster Generator
Paste your keyword list and get it organized into topic clusters based on real word overlap — a transparent method you can verify yourself, with no invented metrics.
Keywords entered: 10
Clusters are built by counting the significant words shared across your keyword list, then grouping any keyword that shares its most common word with at least one other keyword. Keywords with no shared significant word appear under "Other". No external keyword data is used — this groups exactly what you typed.

Frequently asked questions
Does this use real search volume data?
No. This tool only analyzes the text you provide and groups keywords by shared significant words — it never fabricates search volume, competition, or difficulty scores.
Where can I get real search volume for my clusters?
Use Google Search Console, Google Keyword Planner, or another keyword research platform to add volume data to the clusters generated here.
Is there a limit to how many keywords I can paste?
No hard limit, but very large lists (1,000+) may take a moment to process in your browser since everything runs client-side.
