Project overview

Cognee turns ingested data into a self-hosted knowledge graph that agents can remember and query across sessions. Developers use its Python API or CLI to remember, recall, forget, and improve information, combining semantic retrieval with graph relationships. It can run locally, in Docker, through Cognee Cloud, or on a consolidated PostgreSQL memory layer; an LLM provider key is normally required for local setup.
