# GitBook

> GitBook is a documentation platform that helps software teams write, publish, and maintain product docs, API references, and internal knowledge bases. It pairs a collaborative editor with a Git-based docs-as-code workflow, so writers and engineers can work from the same source of truth. In recent years GitBook has leaned into AI - both to help teams draft and keep docs current, and to make published docs readable by AI agents through features like markdown endpoints, llms.txt, and auto-generated MCP servers. It is used by more than two million people and teams including Google, Nvidia, Zoom, FedEx, and Snyk.
