Keyword Clusters

Keyword Clusters is an SEO tool that groups thousands of keywords by meaning directly in the browser.

Keyword Clusters organizes thousands of SEO keywords into topic clusters based on meaning rather than search engine result page overlap. Users paste keyword lists or drop exports from tools like Ahrefs, Semrush, or Keyword Planner to generate intent labels and CSV outputs. The application runs a small sentence-embedding model locally inside the browser tab using WebAssembly and static files. It processes up to 25,000 keywords per run and creates a two-level map of topics, clusters, and keywords. Users can adjust a similarity slider to instantly re-cluster data without waiting for server processing.
