Memory layer that helps AI apps remember users across sessions

About Mem0

Mem0 is a memory layer for AI agents and applications. It stores facts from past conversations and retrieves the relevant ones when a user returns, so responses fit that person.

What it does

Your app sends conversation messages to Mem0, which extracts and updates memories tied to a user ID. When the agent needs context, it searches those memories and adds only what is relevant to the prompt. The aim is to lower token use and keep replies on topic.

Key features

  • Memory tied to user IDs
  • Search memories by question
  • Python and Node.js SDKs
  • Memory compression to cut tokens
  • Plugin for agent harnesses

Who it's for

Developers building chat assistants, support bots or personal tools that should remember preferences. It fits teams that want memory without rebuilding their pipeline.

Pricing and good to know

The project is open source under the Apache-2.0 license. Mem0 also runs a hosted platform, and the quickstart uses an API key from its site. Check the hosted terms and data handling before you store personal information.
