by Mem0 AI

Open-source memory layer for AI agents that enables persistent, personalised interactions by remembering user preferences, past conversations, and context across sessions.

Mem0 (pronounced "mem-zero") is the most widely adopted AI agent memory framework, backed by $24M from YC, Basis Set Ventures, and Peak XV. It adds a persistent memory layer to any AI agent or assistant with as little as three lines of code. The system uses LLM-based extraction to decide what to store, then retrieves relevant memories at query time using semantic search. The optional graph memory tier (Mem0g) adds entity extraction and relationship mapping. AWS selected Mem0 as the exclusive memory provider for their Agent SDK. Used in production by thousands of teams including integrations with CrewAI, Flowise, and Langflow natively. Free tier includes 10K memories. Pro plan at $19/mo adds graph features. Enterprise adds on-prem, SSO, HIPAA BAA, and dedicated SLA. 48,000+ GitHub stars. SOC 2 and HIPAA compliant.
