neo4j-labs/llm-graph-builder
Neo4j graph construction from unstructured data using LLMs
Supports multiple input sources (PDFs, videos, web pages, S3/GCS buckets) and 10+ LLM providers through LangChain, with configurable embedding models and vector search capabilities. Built on a FastAPI backend and React frontend, featuring conversational graph querying, token usage tracking per user, and real-time visualization in Neo4j Bloom. Deployable locally via Docker Compose, separately for development, or to Google Cloud Run with support for both cloud and local LLMs like Ollama.
