About Doc0

doc0 is a hosted service that maps a GitHub repository into a code knowledge graph and generates documentation from it. Every statement in the generated wiki cites the code it comes from, and the index is refreshed when new commits are pushed. The goal is to stop questions about how the code works from always landing on the engineers who wrote it.

From one graph it produces a technical wiki, a user guide written for non-engineers, an API reference that lists detected endpoints with parameters and responses, and a changelog that summarizes merged pull requests. AI agents can query the graph over MCP from tools such as Claude Code and Cursor, while product managers and support staff can ask questions in Slack, Linear or a web chat. doc0 is a commercial, hosted product, and the vendor states that customer code is never used to train models. It offers a 3-day trial, and plans are described on its pricing section.
