| description.long | An open-source framework that enables AI agents to build and query context graphs with historical awareness. Unlike static knowledge graphs, Graphiti's context graphs preserve how information changes over time and maintain provenance to source data, supporting both semantic and graph-based retrieval across evolving real-world data. | - |
