About GitBook

Documentation platform for product and API docs, with Git sync, an editor for non-developers and AI search over published content.

GitBook is a hosted documentation platform used by software companies for product docs, API guides and internal technical knowledge. Writers can edit in a block editor in the browser, while developers can keep the same content in a Git repository through two-way sync, so changes from either side end up in one published site.

Published sites include search, versioning, custom domains and an AI assistant that answers reader questions from the docs. Teams can review changes before they go live, which helps when engineers and technical writers both edit the same pages.

It suits teams who want a docs site without running their own build pipeline. Check how API reference pages are generated from your OpenAPI file, how access works for private docs, and what the export looks like if you move to a docs-as-code setup later.
