cognee

Cognee is an open-source memory platform that gives AI agents persistent, long-term memory across sessions by capturing context and turning it into graph, vector, and relational memory. It solves the problem of agents forgetting information or having disconnected, incomplete memories. The platform targets developers, data teams, and product engineers at startups and enterprises who build AI agents and need scalable memory infrastructure. It is positioned as a self-improving memory engine that integrates with MCP-compatible agents and offers both cloud and on-premises deployment.
