GitBook
Documentation platform with AI answers, Git sync, and collaborative editing.
About
GitBook is a documentation platform for product docs, guides, and knowledge bases, combining a visual block editor with bidirectional Git sync (GitHub, GitLab), OpenAPI support, versioning, and analytics. Its AI features include AI Answers over your docs and an AI assistant on higher tiers.
In 2024-2025 GitBook restructured pricing to a per-site plus per-user model (Premium around $65/site/month plus $12/user/month), a 2-3x increase that pushed many teams to evaluate alternatives. The free tier is limited to one user on a gitbook.io subdomain. Limitation: costs scale steeply for teams managing multiple documentation sites, and AI capabilities are gated behind the higher tiers.
