Knowledge Base & RAG

How to build and maintain an effective knowledge base for accurate AI responses.

CRAB's knowledge base uses retrieval-augmented generation (RAG) to ground AI responses in your business content.

Supported formats

Upload PDF, DOCX, TXT, and Markdown files. Add URLs to crawl public web pages. Each document is chunked and embedded for semantic search.

Best practices

  • Keep documents focused and up to date
  • Use clear headings in your source material
  • Remove outdated policy documents promptly
  • Test common customer questions after each upload

Monitoring retrieval

The dashboard shows which knowledge chunks were retrieved for each conversation, along with relevance scores. Use this to identify gaps in your knowledge base.
