What is Knowledge Base​

Knowledge Base is a feature that allows you to register document files such as PDF and Word as AI Avatar knowledge (added in v1.15.0).

AI Avatars reference Knowledge Base content during conversations (RAG: Retrieval-Augmented Generation) and can provide responses based on registered documents. For example, if you register product manuals, internal regulations, property materials, etc., the AI can answer questions based on that content.

When to Use
  • "I want responses based only on document content"
  • "I want the AI to read the latest specifications"
  • "I want evidence-based responses, not guesses"

    When you select a Knowledge Base, the supplementary instruction field becomes available. Writing additional instructions for the AI here can provide more accurate responses.

    RAG supplementary instruction field Example supplementary instructions: "Decline if not in provided materials, add source file name at the end", etc.

    Example Supplementary Instructions
