Strata

Gives Claude a persistent memory layer that survives session restarts and runs entirely on your hardware. Exposes semantic search over stored thoughts, file vault operations for attaching real documents to memories, and auto-tagging with deduplication checks. The v2.2 update adds PostgreSQL with pgvector for production scale, per-agent API keys with granular permissions, a global MCP kill switch, and CSV audit logs that let you trace exactly which thoughts an agent retrieved and when. Includes a legacy import system for pre-Strata memories using negative IDs. Built to run on a Raspberry Pi with local embeddings via ONNX Runtime. Reach for this when you need your AI to remember context across conversations without sending data to external services.
