How it works
Connect your content
Add a docs site, a GitHub repository, a helpdesk or any of 24 source types. Kelu fetches the content, turns it into clean text and keeps it up to date on its own.
Test the answers
Ask questions on the knowledge base’s Playground tab. Check the citations, then set the tone and instructions in its settings.
