GitBook

GitBook

GitBook is a documentation platform built for modern teams, focusing on accuracy and reliability for both human readers and AI agents. It provides a visual editor, Git Sync for version control, and an AI-powered Assistant that turns documentation into an interactive knowledge base. The platform includes features like an AI Agent for content updates, insights to track user confusion, and authenticated access for private docs. Targeted at developers, technical writers, and product teams, GitBook streamlines creating, maintaining, and publishing technical documentation, API references, and knowledge bases. It offers enterprise-grade security with SOC 2 and ISO 27001 compliance, making it suitable for regulated industries. The tool integrates with GitHub, GitLab, and AI workflows via a dedicated MCP server.

How to use style guides for AI docs reviews in GitBook
With style guides in GitBook, you can train GitBook’s AI Agent on your specific style and voice rules, ensuring that every update — whether it’s created by an AI Agent or a member of your team — matches the tone and style of the rest of your documentation. Learn how to set up a style guide, customize it to match your team’s voice and style, and use it to review content, then flag and fix violations. GitBook transforms documentation into an intelligent knowledge system that connects content, context, and AI — so your docs don’t just exist, they actively learn and get better over time.

GitBook Webinar: Using GitBook Agent in Slack, Linear, and GitHub
Docs fall behind because updating them means context-switching. GitBook Channels fixes that. Product teams consistently tell us that keeping documentation up to date with product changes is their #1 challenge — not because they don't care, but because the friction of switching tools makes it easy to defer. GitBook Channels brings documentation workflows into the tools your team already uses. Now, kicking off a change request is as simple as mentioning @GitBook in a thread. No tab-switching, no lost context, no docs left behind. In this video, we'll show you how Channels works and how teams are using it to close the gap between shipping product changes and updating the docs that explain them. GitBook transforms documentation into an intelligent knowledge system that connects content, context, and AI — so your docs don’t just exist, they actively learn and get better over time.
