Letta (formerly MemGPT) is an open-source framework for building AI agents with long-term memory and self-editing capabilities. It implements a virtual context management system that allows LLMs to manage their own memory hierarchy, enabling persistent state, unbounded context, and adaptive memory across conversations.
Memary is an open-source knowledge graph memory system for AI agents. It specializes in building and querying complex reasoning trails rather than simple chat log retrieval, using knowledge graphs to track entities, relationships, and reasoning chains across agent interactions.
Tools and frameworks for adding persistent, long-term memory to AI agents and LLM applications. These systems manage conversation history, user preferences, and learned context across sessions, enabling more personalized and context-aware AI interactions.
