GitBook

GitBook is a platform for writing and publishing product documentation, with GitBook Agent to draft and maintain pages and GitBook Assistant to answer reader questions from the docs. Software teams use it for public help centers, API docs and internal knowledge.

GitBook Agent looks for content that needs improving, drafts updates and reviews changes so the docs keep pace with the product. On the reader side, Assistant can be embedded in your site or app and answers using your documentation, connected knowledge sources and user context, while a lighter Ask mode gives short answers from the search box.

AI translation keeps localized versions in sync when the source text changes, and published sites are optimized for LLMs to read. AI use is billed in credits, with a bundle included in each paid site plan. Sites are priced separately from extra team members, and Enterprise adds SAML SSO and migration help.
