DeepMem

DeepMem is a memory-as-a-service platform designed as a drop-in replacement for Mem0. It provides AI agents and applications with persistent, searchable conversation memory through a fully compatible HTTP API. The service achieves sub-50ms p95 latency and offers a generous free tier with no credit card required.

The platform features hybrid retrieval combining vector search, BM25, entity boosting, and time-decay ranking. It includes semantic caching to reduce LLM calls, async batched fact distillation to lower costs, and multi-tenant isolation with GDPR compliance. DeepMem is available as a managed cloud service or self-hostable open-source deployment, with migration from Mem0 requiring only a single import line change.
