# Knowledge base (Support AI Chat)

## Quick Start

What is Knowledge Base?

Knowledge Base allows AI to reference your internal documents, policies, and data stored in Vector DB. When enabled, AI analyzes your prompts, retrieves relevant content from selected vector folders, and uses that information to generate accurate, context-aware answers.

<br>

What you can do:

\- Upload documents to Vector DB

\- Enable Knowledge Base in AI Chat

\- Ask questions that reference your internal data

\- Get answers grounded in your documents

\- Combine Knowledge Base with Web Search for comprehensive research
