## Key features

- **Block-based editor:** A visual editor built from blocks, including custom ones. Added users collaborate through change requests and content reviews before edits are published.
- **Git Sync:** Two-way sync with GitHub or GitLab lets a team branch, review and merge documentation like a pull request. It is included on every plan, the Free one too.
- **Published docs sites:** Sites get unlimited traffic and preview deployments on every plan. Custom domains, branding and redirects start on Premium; sections and site groups need Ultimate.
- **AI search and Assistant:** On Premium, readers get short answers straight from the search box. Ultimate adds the Assistant, a chat sidebar that can also draw on connected sources such as GitHub and Slack.
- **GitBook Agent:** Writes, edits and updates documentation and flags content that no longer matches the product. Free accounts are limited to 10 messages a week.
- **API docs and LLM-ready output:** OpenAPI specifications become interactive API playgrounds. Every site also gets llms.txt files, Markdown versions of pages and its own MCP server.

## Good for

- Public product and API documentation for software companies
- Teams that want docs reviewed and merged in a Git workflow

## Worth knowing

- Paid plans combine a per-site fee with $12 per user / month, and guests and read-only members cost the same as other members.
- The pricing page shows annual-billing prices and advertises 2 months free; month-to-month rates are not shown in its default view.
- The Free plan covers a single user and leaves out custom domains, AI search and AI writing.
- SAML SSO is limited to Enterprise; the AI Assistant, adaptive content and authenticated access need Ultimate at $249 per site / month.
