The New GitBook

What it does

GitBook is documentation infrastructure for creating, publishing and maintaining product and developer docs. It bills itself as a 'knowledge layer for AI', keeping docs accurate and machine-readable, and offers Git sync, an AI setup agent and a GitBook MCP server for connecting docs to AI assistants.

How to use: Sync your docs to GitHub or GitLab and collaborate in GitBook’s WYSIWYG editor or your IDE. Add your OpenAPI spec file and GitBook will do the rest, generating helpful, practical docs in seconds. Effortlessly migrate your docs to GitBook, add your own branding, and publish in a click.
