# Open WebUI Docs Open WebUI documentation is available as regular HTML and raw Markdown. Start at https://docs.openwebui.com/sitemap.xml to discover pages. For any docs page, append `.md` for Markdown or `.txt` for plain text. Use https://docs.openwebui.com/api/search?q=YOUR_QUERY for canonical docs search. The search endpoint uses Open WebUI's deterministic docs ranking: 1. Split the query into lowercase keywords. 2. Search URL paths and Markdown content separately. 3. Rank by number of distinct keyword hits; break ties with shorter paths. 4. Prefer path matches first, then content matches, deduplicated. Example: - https://docs.openwebui.com/features/extensibility/mcp - https://docs.openwebui.com/features/extensibility/mcp.md - https://docs.openwebui.com/api/search?q=mcp%20notion Use canonical HTML URLs when citing sources.
