Why Cobalt

Everything a modern docs stack needs

Write in MDX, publish on merge, and let your readers — human or agent — find the answer on the first try.

Ship docs in minutes

Point Cobalt at a repo and get a polished, searchable site with previews on every pull request.

Answers, not search results

AI chat is grounded in your content, cites the page it came from, and stays current as you write.

API docs from your spec

Drop in an OpenAPI file and get interactive playgrounds, SDK snippets, and typed examples.

Analytics that matter

See the questions readers ask, the pages that fail them, and what to write next.

Enterprise ready

SSO, private previews, granular roles, and audit logs — available on every plan that needs them.

Yours to extend

Custom components, themes, and MDX. Escape hatches everywhere, defaults you rarely fight.
