# Overview of External Knowledge Bases

AI Assistants in MangoApps can connect to your company’s external knowledge bases—enabling them to answer user queries using content stored outside of MangoApps. Supported sources include **SharePoint**, **Confluence**, and **internal websites or pages**, expanding the reach and relevance of AI-powered responses.

These setup guides provide step-by-step instructions to connect and configure each source. You will learn how to authenticate securely, filter content using regex, and set up automatic sync intervals—ensuring your AI Assistant always provides accurate and up-to-date information. Once connected, the user experience remains consistent, whether the AI Assistant is using internal MangoApps data or content from external systems.
