What it does
Ingests PDFs, documents, YouTube videos and web pages, extracts the entities and relationships with an LLM, and writes the result into Neo4j as a queryable knowledge graph — useful when the interesting information is the connections rather than any single document. Official Neo4j Labs project. Extraction errors are inevitable and a diagram makes them look authoritative, so verify names and links against the source before drawing conclusions. Apache-2.0.
