Mem0
Plug-and-play memory infrastructure for AI agents and applications, providing persistent memory across sessions.
About Mem0
Mem0 is memory infrastructure for AI agents and applications: it lets context persist across sessions. Developers can create, search, update, and manage memories through the REST API, organizing them by user, agent, and custom entities, or integrate it into existing apps via SDKs; the official site also provides integration guides for 22 popular tools. In addition to the cloud-hosted service, Mem0 offers an open-source version that can run on your own servers as a library or a Docker stack, keeping data within your own infrastructure. On security, the official site states it is compliant with SOC 2 (Type 1), HIPAA, and GDPR, with logs for every memory read and write.
