About

Mem0 gives your agent a memory that persists between sessions, so it remembers user preferences, facts, and context instead of starting blank every chat. The hosted Hobby plan is free with 10,000 memory adds per month and unlimited end users, no credit card required, and the core is open source if you would rather self-host.

Details
