The AI support co-pilot that drafts grounded, cited replies from your own docs — reviewed and sent by your team.

Upload your knowledge
Drop in help docs and FAQs. They're chunked, embedded, and indexed in the background.
Questions arrive
Customers write in through the widget or your API. Capstan retrieves the relevant passages and drafts a cited reply.
Review and send
Agents see the draft, its sources, and a confidence score. Edit, send, done — or take over when it escalates.
Opinionated where it counts
Grounded in your docs
Answers are retrieved from your own help articles with pgvector semantic search — never invented.
Citations on every claim
Each draft cites the exact source passages it used, so agents can verify before they send.
Escalates instead of guessing
When retrieval confidence is low, the question goes straight to a human — no confident nonsense.
Humans stay in the loop
The AI drafts; your team reviews, edits, and sends. Every reply carries a person's judgement.

A one-line embeddable widget and an org-scoped REST API bring questions in from any surface.
