MemMachine
An open-source memory layer that stores conversational history and user preferences for AI agents across sessions.
About MemMachine
Agents need a way to retrieve earlier conversations and user facts after the current context ends.
Who it’s for
- Developers building personalized AI assistants
- Teams adding persistent memory to agent workflows
When to consider it
Consider MemMachine when your agents need separate conversational and profile memory through an API, SDK or MCP server.
Tradeoffs & limitations
