Overview
GitBook was founded in 2014 by Aaron O'Mullan and Samy Pesse in Lyon, France, originally built around Git-based, Markdown-driven documentation workflows.
It has since evolved into an AI-native documentation platform combining a block-based visual editor, Git sync, API reference tooling, and AI search, writing, and question-answering features.
Key Features
Core capabilities include a collaborative block-based editor, GitHub/GitLab sync, change requests (pull-request-style content review), and built-in API playgrounds for interactive API reference docs.
Higher tiers add an AI Assistant grounded in a team's own documentation, AI Insights, adaptive content, authenticated/gated access, and enterprise features like SAML SSO.
Pricing
GitBook prices per published site: Free for a single basic site, Premium at $65/site/month, and Ultimate at $249/site/month (both billed annually, plus $12 per additional user/month).
A custom-priced Enterprise tier adds SSO, white-glove migration, and dedicated support for larger organizations.
Key Features
Block-based visual editor — A modern, collaborative editing experience for authoring documentation without needing to write raw Markdown.
Git sync (GitHub/GitLab) — Two-way synchronization with Git repositories for documentation-as-code workflows.
API playgrounds — Interactive, testable API reference documentation generated alongside narrative content.
Change requests — Pull-request-style review and approval workflow for proposed documentation edits.
AI Assistant and AI search — An AI agent that answers questions grounded in a team's own documentation content, plus AI-powered search.
Real-time collaboration — Multiple team members editing documentation simultaneously, similar to Google Docs-style collaboration.
Custom domains and branding — White-labeled documentation sites with custom domains, fonts, and branding on paid tiers.
Authenticated/gated access — Restrict documentation access to logged-in or authorized users on higher tiers.
