What it is

Keyword Clustering is a web tool that groups keyword lists by semantic similarity and search intent for website pages. It uses OpenAI’s GPT model to determine the number and size of clusters automatically. Each cluster can include a suggested page title and meta description. The tool accepts pasted keywords, CSV, TXT, or Excel files, and can import from Keywords Everywhere Favorites. It can add monthly search volume and cost-per-click data from Keywords Everywhere, including total volume and average CPC for each cluster. Results export to CSV or Excel, and read-only links can expire after 24 hours, 7 days, or 30 days. The free plan costs nothing, allows up to 10,000 keywords per job, and has no subscription fees or premium tiers. Daily limits depend on the Keywords Everywhere plan. Sign-in requires a Keywords Everywhere API key. Jobs remain for one year before deletion.
