Used by documentation and developer-experience teams
Where product adoption gets stuck
The answer is in your docs. Getting to it is the hard part.
i.
Users miss the relevant detail
A setup guide, an API reference, and a troubleshooting page can each explain part of the answer. Readers still need to work out how those pieces fit their question.
ii.
AI tools need your product context
A coding assistant can know the language and still miss how your API works. Developers need a way to bring your maintained documentation into the tools they use.
iii.
Your team keeps filling the gaps
Repeated questions take time to answer, but page views rarely tell you which explanation is missing. The questions themselves help you decide what to document next.
Your existing docs, more ways to use them
Meet users and agents where they work
Keep publishing on Docusaurus, Sphinx, MkDocs, or your existing platform. Connect your sources once and choose where people can use them. Availability depends on your plan.
In their AI tools
Give agents your product context
Make your documentation available inside Codex, Claude Code, ChatGPT, and other compatible tools. Developers can retrieve product guidance while implementing an integration.
