AI memory

Mem0

Gives AI assistants a memory so they can remember people's preferences across conversations.

What it does

Mem0 (pronounced "mem-zero") is a memory layer for AI assistants and agents. It lets an app remember things about a user, a session or an agent, such as preferences or past requests, so later conversations can be more personal.

Its makers suggest uses like customer support bots that recall past tickets and assistants that keep context over time. Developers can use it as a code library, run it on their own server, or use the makers' paid cloud service.

Its makers publish benchmark results for their memory method, and note that the scores reflect their managed platform, which has extra features not in the open-source version.

Who it's for

Developers building chatbots or AI agents that need to remember users.

Can I use it without coding?
