How it works

Paste a list of questions, one per line. The clusterer assigns each question to one of seven canonical shapes - how-to, definition, reason, comparison, recommendation, timing and choice - then identifies the shared keywords inside each cluster so you know what the group is really about.

Why cluster by shape, not topic

  • Shape determines page shape. AI assistants route "how" queries to tutorial pages and "vs" queries to comparison pages. Same topic, different citation target.
  • Shared keywords reveal intent. The overlap inside a cluster is the tight phrase set you should mirror in the H1 and first paragraph of the answer page.
  • Cluster size = priority. The largest clusters are the pages you should ship first, regardless of raw volume estimates.
