Cortex – Local-first AI memory engine, beats Mem0 on LoCoMo, encrypted, free

Hi HN, I built Cortex because I got tired of AI memory solutions that send your most personal data to someone else's server.

  Cortex is a 4-tier memory engine (episodic → semantic → procedural)
  that runs 100% on your device. Pure Rust, 3.8MB, 62µs ingest.

  LoCoMo benchmark: 73.7% overall, beating Mem0 (66.9%) on all 4 categories.
  AES-256-GCM encrypted sync via your own iCloud/GDrive/Dropbox.
