For engineering & product

Docs that live next to the work

Specs, runbooks, architecture diagrams, and decisions — connected, current, and searchable.

Start free

Keep engineering and product knowledge in one place: write specs and RFCs, map architecture with editable flowcharts, document runbooks, and track decisions — all backlinked and searchable so nothing goes stale in a forgotten doc.

Sound familiar?
  • Specs and RFCs scattered across tools and drives.
  • Architecture diagrams that go stale the moment they’re exported.
  • Runbooks and decisions no one can find during an incident.
