Answers from your knowledge, with receipts
Turn your docs and product knowledge into a chat assistant that answers in your voice and cites its sources, grounded in retrieval, never guessing.

Chat you can actually trust
Grounded in your content
Answers are generated only from your indexed sources, with no hallucinated facts or stale training data.
Inline citations
Every claim links back to the source chunk it came from, so users can verify in one click.
Multi-turn chat
Follow-up questions keep context, turning a single answer into a real conversation.
Streaming responses
Tokens stream in as they're generated for a fast, responsive feel on any surface.
MCP for agents
Expose the same knowledge to Claude and other agents over the Model Context Protocol.
Guardrails
Scope answers to specific collections and fall back gracefully when there's no good source.
Web widget, API, or MCP
Embed chat with @hopfield/react, stream answers from the API, or connect an agent over MCP, all backed by the same knowledge base.
