GitBook is a documentation platform for building and maintaining technical and product documentation, with tooling to keep docs synced with code and AI features aimed at making docs answerable directly.

Guru is an enterprise knowledge-management platform that organizes and continuously verifies company information — policies, procedures, product info — so employees and connected AI tools can retrieve accurate, permission-scoped answers.
