Cortex, a privacy-focused AI memory engine running entirely locally, outperforms Mem0 on benchmarks while keeping user data encrypted on personal devices.

Cortex is a 4-tier memory system (episodic, semantic, procedural) built in pure Rust, weighing only 3.8MB and processing data in 62 microseconds

Achieves 73.7% on LoCoMo benchmark, beating competitor Mem0's 66.9% across all 4 categories

All processing happens locally on users' devices with AES-256-GCM encryption for syncing via iCloud, Google Drive, or Dropbox

Created to address privacy concerns with existing AI memory solutions that send personal data to external servers
