GitBook is a technical documentation platform that helps teams write, publish, and maintain product docs that connect with users and AI agents. It supports docs-as-code via Git Sync, includes an embedded AI Assistant that answers user questions, and ships every site with an MCP server for AI agents.
GitBook Assistant answers user questions inside your product or docs, drawing from your content, community discussions, and other connected sources. GitBook Agent proactively suggests doc improvements based on support tickets and changelogs. Every site ships with an MCP server so AI agents can read your docs.
If your team publishes technical or product documentation, GitBook is one of the cleanest options around — easy enough for non-technical writers but with real Git sync for engineers. The built-in AI Assistant and MCP server mean your docs work for both humans and AI agents, which matters more every quarter.
