## What is Cluster?

Content without architecture is just posts. Cluster turns a seed topic (plus an optional keyword list) into a pillar-and-cluster map: subtopics grouped deterministically, search intent classified, priorities scored.

WHAT YOU GET
An expandable tree — pillar, subtopics, supporting keywords — with intent badges (informational, commercial, transactional, navigational) and priority scores. Export the map as CSV or Markdown for your content calendar.

GROW THE MAP
Connect an AI provider to expand the map with subtopic ideation; the deterministic core works entirely offline.

PRIVATE BY DESIGN
No accounts, no analytics, no tracking.
