LongMem — long-term memory for AI agents

LongMem is open-source, self-hostable, privacy-first memory infrastructure for AI agents. Store text and files, search them semantically (hybrid vector + full-text), and let memory evolve over time — automatic fact extraction, updates and supersedes, and forgetting. Multi-tenant with strict per-tenant isolation, graph memory, connectors, and a one-line API. Built in the EU.
