What it is

An all-in-one RAG system that reads documents with Docling, stores them as an OpenSearch index, and answers questions about them in an LLM-powered chat window. Retrieval and ingestion flows are editable in Langflow's visual builder, and the instance exposes a REST API, Python and TypeScript SDKs, and a built-in MCP server. Teams that want a private knowledge base their staff and AI assistants can search run it with Docker or Podman.
