MemMachine - An open-source AI memory system that supports multiple memory types.

What is MemMachine?

MemMachine is an open-source AI memory system designed specifically for AI agents, providing short-term, long-term, and personalized memory capabilities. Through contextual memory, semantic memory, and user profile memory, MemMachine helps AI applications learn, store, and recall past conversation data, enhancing the interactive experience. MemMachine supports various deployment methods and database combinations, such as Neo4j and PostgreSQL, enabling efficient memory management. MemMachine is suitable for various scenarios such as CRM, healthcare, and financial management, significantly improving the intelligence level of AI agents.

MemMachine's main functions

• Multi-type memory support:
  • Episodic MemoryRecords details of every interaction between the user and the AI agent, helping the agent understand the context of the current conversation.
  • Semantic memoryIt summarizes and aggregates users' long-term information, providing structured knowledge storage.
  • User profile memoryIt creates a continuous profile of users, recording preferences, historical behaviors, etc., for personalized responses.
• Cross-session memory persistence:The memory layer spans multiple sessions, agents, and large language models, supporting the storage and retrieval of long-term memory and building complex user profiles.
• Personalized Interaction:Provide customized responses based on users' historical data and preferences to enhance user experience and interaction depth.
• Multi-model compatibility:It supports a variety of AI models, including private models and cloud service models, avoiding vendor lock-in.
• Flexible deployment methods:It supports local and cloud deployments and integrates with proxy systems through various interfaces such as RESTful API and Python SDK.
• Data persistence and management:The Neo4j graph database is used to store contextual memories, and the PostgreSQL relational database is used to store user profile memories, ensuring data structure and efficient querying.

MemMachine's Technical Principles

• Memory architecture design:
  • Episodic memory: Store session events using a graph database (such as Neo4j) to efficiently manage complex relationships and contexts using a graph structure.
  • Semantic memoryUser information is semantically processed and stored in a structured database for easy retrieval and analysis.
  • User profile memoryBased on users' historical behavior and preferences, dynamically updated user profiles are built and stored in an SQL database.
• Multi-Model Access Layer (MCP):It provides a multi-model compatibility protocol (MCP), supports multiple interfaces such as RESTful API and Python SDK, and supports memory services for different AIAgent system calls.
• Data persistence and query optimization:The Neo4j graph database is used to store contextual memories, supporting fast contextual queries and relational reasoning.Use PostgreSQL to store user profile memories, ensuring structured data and efficient updates.
