Mem0

What it is for

Mem0 is a hosted memory layer for agents: the official platform still (see the cover: memories table, add/search, and project switcher) is the product. Use it when the job is persist user memories across sessions via an API.

License is hosted commercial plus an open-source SDK. Hobby prints Free. Starter is the first public paid card.

What makes it unique: the cover is Mem0’s own platform console — memories, add requests, retrieval — from official docs, a product dashboard rather than a logo tile.

Key features

• Add / search memories — extract facts from a turn and retrieve them later (quickstart).
• Graph memory — people, places, and concepts become nodes that boost multi-hop recall (graph).
• Dream — background job that merges duplicates and retires stale facts (Dream).
• Temporal reasoning — rank memories whose event dates match “last week” or a reference_date (temporal).
• Entity scoping — isolate stores with user_id, agent_id, app_id, or run_id on each call (quickstart).
• Memory filters — AND/OR queries on categories, metadata, and time ranges (filters).

Who it's for

Best fit: agent builders who want a managed memory store and will stay inside the monthly add/retrieve caps.
