tom_doerr · x · 2026-08-07
Neo4j Labs has released an open-source project called llm-graph-builder, designed to convert unstructured data (such as PDFs, web pages, and YouTube videos) into structured knowledge graphs.
Built on the LangChain framework, the tool supports file uploads from local storage, GCS, and S3. It allows users to select their preferred LLM to extract entities and relationships, ultimately storing the generated graph in a Neo4j database. The project has already garnered over 5,000 stars on GitHub.
