What is Mem0?
Mem0 is an open-source memory layer and hosted platform that extracts facts from conversations and returns relevant memories at prompt time. Developers add it to agents and assistants so they remember users across sessions without huge context windows.
Mem0 stores memories in a vector store with an optional knowledge graph and retrieves only what is relevant, which cuts token use compared with sending full chat history. SDKs exist for Python and JavaScript, with integrations for common agent frameworks.
The open-source version can be self-hosted with your own vector store. The managed platform has a free tier and paid plans that add graph memory, analytics and higher limits.
