Kelu turns your documentation, repositories, wikis, tickets and community threads into a knowledge base. It answers questions from that content with numbered citations, and says so when the content does not cover a question.

How it works

1

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.
2

Test the answers

Ask questions on the knowledge base’s Playground tab. Check the citations, then set the tone and instructions in its settings.
3

Publish where people ask

Add the widget to your site, connect a bot or a helpdesk, or give an AI tool access through MCP.
