cognee

Cognee is a free and open-source memory platform that gives AI agents permanent long-term memory between sessions. It converts documents, code, and conversations into a graph of information hosted on your own server that agents can call and reuse. Without the LLM key, it can run on the CPU with local GLiNER and embedded models; Python requires 3.10 ⁇ 3.14.
