About Mem0

Mem0 is an open-source memory layer for AI agents and applications, providing persistent context across sessions and agents. It offers a drop-in memory infrastructure that reduces token costs and improves response times through a Memory Compression Engine that condenses chat history into compact memories. The platform includes SDKs for Python and Node.js, and supports integration via API. Mem0 is available as a hosted platform with free and paid tiers, or as open-source software under Apache-2.0 license. Use cases include healthcare, education, e-commerce, customer support, and sales CRM.
