Knowledge Base (Early Access)

Connect your flow to a searchable knowledge base (KB) so the model can answer with facts from your docs.

When to use

  • You want grounded answers from your own content (FAQs, guides, PDFs).
  • You need citations/sources for transparency.
  • You prefer retrieval-augmented answers over model memory.

Status: Early Access — features and output shape may evolve.

What it does

  • Indexes your content (files/URLs/connectors) into chunks.
  • Retrieves the most relevant chunks for the user's query.

This node is typically used for RAGs (Retrieval Augmented Generation)
