Gives Claude a persistent memory layer that runs entirely on your machine. You get 29 MCP tools for ingesting conversations, searching across four memory tiers (working, episodic, semantic, procedural), and retrieving context with token budgets. The people graph resolves identities across channels, Bayesian beliefs self-correct with evidence, and temporal queries understand "recently" versus "first time." Everything stays local in SQLite with optional encrypted sync to your own cloud storage. Benchmarks show 568µs retrieval versus 300ms for cloud alternatives, and it outscores Mem0 by 6.8% on the LoCoMo academic memory benchmark while costing nothing. Reach for this when you want Claude to remember across sessions without sending your data to a third party API.
