Memory for AI agents that never leaves your device.

Private. Free. Local. — a memory engine for personal AI agents.

Your AI's memory lives on your device — your data never leaves, never costs, never spies. Pure Rust. 3.8MB binary. No third-party servers in the data path, zero telemetry, zero cost. Syncs through your own cloud storage. (On-device semantic search downloads a ~30MB model once on first use, then runs fully offline — or go 100% offline with CORTEX_NO_EMBEDDINGS=1. See Security & Privacy.)

What you get

🔒 Private by default — memories live in a local SQLite file, never leave your device, zero telemetry (CI-enforced).
🧠 Real memory, not a text file — 4 tiers, multi-signal retrieval, self-correcting Bayesian beliefs, a cross-channel people graph.
⚡ Sub-millisecond — 156µs ingest, 568µs search. ~528× faster than cloud memory APIs, with no network round-trip.
🔌 Drop-in for any agent — one MCP server gives Claude Code / Claude Desktop (or any MCP client) persistent cross-session memory.
☁️ Yours across devices — optional end-to-end-encrypted sync through your own iCloud / Drive / Dropbox. No server of ours, ever.

See it remember across sessions — ~30 seconds:

brew install gambletan/tap/cortex-mcp-server          # or: cargo build --release -p cortex-mcp-server
claude mcp add cortex-memory -- cortex-mcp-server ~/.cortex/memory.db

Tell Claude "remember I deploy on Fly.io and always run tests before pushing." Open a brand-new session and ask "how do I deploy this project?" — it answers from memory, 100% on your machine.

⭐ If that's useful, give it a star — it helps others find a memory engine that respects their privacy.

LLMs start blank every session — they forget your name, your preferences, yesterday's conversation, last week's decision. The usual fixes are flat text files (no ranking, no decay), keyword grep, or cloud APIs that add 200–500ms, charge you, and ship your personal data to someone else's server. Cortex gives your AI structured, self-evolving long-term memory that persists across sessions and channels — all local, all yours. Your memories are not a cloud provider's training data, a startup's monetization asset, or a surveillance target.

Cortex vs Mem0 vs OpenAI Memory

	Cortex	Mem0	OpenAI Memory
Privacy	100% local, zero cloud	Cloud API (your data on their servers)	OpenAI servers
Latency	156µs ingest, 568µs search	~200-500ms	~300-800ms
Cost	Free, forever	$99+/mo (Pro)	ChatGPT Plus ($20/mo)
Memory tiers	4 (Working/Episodic/Semantic/Procedural)	1 (flat)	1 (flat)
Bayesian beliefs	Self-correcting with evidence	No	No
People graph	Cross-channel identity resolution	Paid tier only	No
Conversation compression	Automatic session summarization	No	No
Relationship inference	Pattern-based (EN + CN)	No	No
Temporal retrieval	Intent-aware ("recently" / "first time")	No	No
Contradiction detection	Automatic with confidence scores	No	No
Consolidation	Episodic → Semantic auto-promotion
