Mem0 (formerly EmbedChain) is a memory layer for AI applications that gives LLMs and agents persistent, personalized memory. It automatically extracts, stores, and retrieves relevant memories from conversations, enabling AI systems to remember user preferences, past interactions, and context across sessions. Mem0 supports multiple storage backends and integrates with popular LLM frameworks.
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.
