Private. Free. Local. — Memory engine for personal AI agents.

Your AI's memory lives on your device — never leaves, never costs, never spies. Pure Rust. 3.8MB. No third-party servers. Zero telemetry. Zero cost. Syncs through your own cloud storage.

Philosophy: Your memories are yours — not a cloud provider's training data, not a startup's monetization asset, not a government's surveillance target. Cortex runs 100% on your hardware, stores everything in your own database, and syncs only through your own cloud storage (iCloud, Google Drive, OneDrive, Dropbox). No middleman ever sees your data. No API key required. No account to create. Just plug it into your AI agent and it remembers — privately, permanently, and at sub-millisecond speed.

LLMs start blank every session. Your assistant forgets your name, your preferences, the conversation you had yesterday, the decision you made last week. Current "memory" solutions are flat text files, keyword grep, or cloud APIs that add 200-500ms latency, charge you for the privilege, and send your personal data to someone else's server.

Cortex fixes this. It gives your AI a structured, queryable, self-evolving long-term memory that persists across sessions, channels, and contexts — with Bayesian beliefs that self-correct, a people graph that resolves identities across platforms, and sub-millisecond performance on everything. All running locally, all yours.
