The Neo4j LLM Knowledge Graph Builder is an innovative online application that transforms unstructured text into a knowledge graph with no code and no Cypher, providing a "magical text-to-graph" experience. It uses ML models (LLMs) to extract entities and relationships from PDFs, web pages, YouTube videos, and other sources, and constructs a graph format using Neo4j's capabilities. The application provides a seamless user interface for data ingestion, entity recognition, graph construction, and visualization of the generated knowledge graph. With its Retrieval-Augmented Generation (RAG) chatbot, users can interact with their data in a natural language query and receive explainable insights into their data. The LLM Knowledge Graph Builder is part of Neo4j's GraphRAG Ecosystem Tools and offers friction-free access to this powerful technology for GenAI applications.
