GitBook

What it is for

GitBook is a docs site with a Git sync and an AI assistant: you write in blocks (or sync GitHub/GitLab), publish a site, and optionally spend AI credits on Ask / Chat / Agent. Use it when the job is product docs that also speak MCP, not when you need a $20 chat seat.

What makes it unique: the cover is the official GitbookIO/gitbook GitHub file list — the OSS docs frontend — not a pricing card.

Key features

• Docs site — a published documentation site from the block editor (pricing). One site. Custom domain, analytics, and redirects are Essential SKU of this.
• Git sync — GitHub or GitLab as the source of truth (all plans). A repo door, not the editor.
• API reference — auto-generated interactive API docs from your spec (all plans). A reference, not a guide page.
• AI Assistant — Ask on Essential; Chat sidebar + insights on Ultimate (pricing). A reader assistant. Credits (2,000 Essential / 10,000 Ultimate) are the meter of this.
• GitBook Agent — writes and edits the docs for you (Ultimate+). An author agent, not the reader Chat.

MCP / WebMCP on every published site is a door of the site. Channels (Slack / Linear / GitHub) and adaptive / authenticated content are Ultimate SKU. $12/user is the seat meter. The editor “Publish” is ops.

Who it's for

Best fit: solo writers who will stay on Free $0, then buy Essential at $65/site/month billed annually plus $12/user when they need a custom domain, analytics, and AI Ask.

Pricing

Verified 2026-10-22 (Asia/Shanghai) from gitbook.com/pricing. Public cards are annual (“2 months free”). Essential and Ultimate include a 14-day trial.

• Free — $0. Individuals. Block editor. GitHub/GitLab sync. Auto API docs. Preview deployments. Published sites expose MCP / WebMCP. No team invites, no custom domain.
• Essential — $65/site/month + $12/user/month. $20 AI credits (2,000). AI Assistant Ask. Team invites. Custom domain, analytics, feedback, redirects, reusable content.
• Ultimate — $249/site/month + $12/user/month. $100 AI credits (10,000). Assistant Chat + AI insights. GitBook Agent. Adaptive content. Authenticated access. Sections/groups. Channels.
• Enterprise — custom. SAML SSO, white-glove migration, and the rest of Ultimate.

Confirm the annual vs monthly toggle at checkout; taxes follow your location. Unused AI credits follow the site’s billing docs.

Limitations / costs

• Free is one person and a GitBook domain. Custom domain starts at Essential.
• $65 / $249 are per site, then $12/user stacks.
• A docs site, not a notebook. For a notes+canvas workspace see AFFiNE. For developer docs that are more API-reference-first see Mintlify.

Alternatives

• Mintlify — API-native docs when you do not want a GitBook editor.
• Notion AI — a wiki when the job is internal notes, not a public docs site.
• AFFiNE — local-first docs + whiteboard when you will self-host.
