About GitBook
GitBook started as a tool for writing books in Markdown and is now a hosted platform for public product documentation, API references and internal docs. Writers use a block editor in the browser, while developers can keep content in a GitHub or GitLab repository and sync both ways, so docs can be reviewed like code. Published sites get search, custom domains, versioning and an AI assistant that answers reader questions from the content, and GitBook can generate interactive API reference pages from OpenAPI files. It also exposes published docs to AI coding tools through an MCP server. Pricing is per docs site rather than only per seat: there is a free plan for individuals, then paid site plans with an extra charge for each additional team member, and custom enterprise pricing. It is browser-based. It suits software companies that want good-looking public docs without running their own static site pipeline, though teams wanting a general internal wiki may find the per-site model awkward.
Best for: Software companies publishing product and API docs that want Git sync without building a site.
