MemMachine.AI – Open-source memory layer for stateful AI agents

Summary: MemMachine.AI is an open-source memory layer that enables AI agents and LLM applications to retain context across sessions, improving response accuracy and reducing token costs through automated context engineering and prompt augmentation.

What it does

It provides a multi-layered memory system including Episodic and Personalization Memory that persists across sessions and models. MemMachine can be deployed as an MCP server, accessed via RESTful API, or integrated with a Python SDK, supporting any LLM.

Who it's for

Developers building AI agents or LLM applications requiring persistent, stateful memory across interactions.

Why it matters

It solves the problem of AI agents’ lack of memory, enabling them to remember past interactions and deliver more intelligent, context-aware responses.
