# AI Knowledge Graph This view lists 24 of 56 matching AI Knowledge Graph AI tools. The displayed tools have a combined 3.24M monthly visits; Connected Papers records 750.58K monthly visits. AI knowledge graphs extract entities and relationships from documents, databases, and web content, then organize them into queryable graphs that power search, recommendations, and retrieval-augmented generation. Teams building RAG pipelines, research tools, or enterprise search rely on them to give language models structured context instead of raw text. Evaluate ingestion formats, ontology flexibility, graph query support such as SPARQL or Cypher, and integration with your vector store. | Metric | Value | | :--- | :--- | | Group | Education &
