Mem0 Memory Service overview

API-based memory service that automatically extracts, stores, and retrieves relevant memories from conversations. Provides user-level, session-level, agent-level, and organization-level memory scopes through a simple add/search API. Uses an LLM to identify facts, preferences, and decisions from conversations and persists them without manual curation. Supports multiple vector store backends (Chroma, Qdrant, Pinecone) for semantic retrieval. The closest third-party analog to Claude Code's auto-memory system, with the key trade-off being accuracy of automated extraction.
