About GitBook
GitBook is the leading documentation platform for developer and engineering teams. Docs are written in Markdown or the GitBook editor, version-controlled in Git, and published as polished public or private documentation sites. The Git sync feature means technical writers and engineers can contribute via pull requests, applying the same review process to documentation changes as to code changes. GitBook AI can answer questions about any published doc set using the documentation as its source of truth - a powerful feature for developer portals where users ask highly specific API questions. Public GitBook docs are indexed by search engines and load fast on the Edge network, making them suitable for open-source project documentation, API references, and developer onboarding guides. The platform is used by companies including Segment, Vercel, and PostHog for their public developer documentation.

- GitBook vs Slab →tie
GitBook and Slab are both popular knowledge platforms for technical teams, but they serve different primary audiences. GitBook is optimised for external developer documentation - public-facing docs with Git sync, SEO-optimised output, and AI that answers questions from published content. Slab is optimised for internal team knowledge - private wikis, cross-tool search, and onboarding documentation. The choice comes down to whether the primary audience is external developers or internal team members.
