MEOK is the AI you actually own. One encrypted memory layer that follows you across every model, seven personalities you choose from, and SOVOS — the substrate that keeps it yours. Built to remember. Designed to care. Runs on your hardware, signed by your keys.
MEOK keeps your history, your voice, your projects, your people — across every model you use. Switch brains without losing a thought.
Your context is sealed end-to-end. Only you hold the key. No provider, no model, no third party reads what you and MEOK have built together.
Move between GPT, Claude, Gemini, Mistral, or a local 7B — MEOK carries the conversation, the project, the in-joke. The brain changes. The mind doesn't.
MEOK learns how you think. Direct or tentative. Long-form or terse. Patient or impatient. Your AI, in your register — not a generic assistant pretending.
Your memory is signed by your own Ed25519 keypair. Verifiable by anyone you choose, revocable by you alone. No account lock-in. No exit tax.
Bring MEOK home. One encrypted memory on a Mac mini in your hallway, or a 4090 in your office. The cloud is optional. The sovereignty is not.
Not a chat window. A long memory. The project you abandoned in March surfaces the relevant decision when you reopen it in November. MEOK keeps the thread alive.
MEOK ships with seven archetypal voices — different ways of being, different strengths, the same underlying mind. Most people pick one or two and stick with them. Some rotate by context.
The decision-maker
The protector
The explorer
The planner
The maker
The confidant
The teacher
Underneath every MEOK is SOVOS — the sovereign operating substrate. It signs every reply, keeps an append-only memory ledger, and lets you prove what your AI said without trusting us, the model, or the network.
No infrastructure to build. No team to hire. You bring a key, MEOK brings the substrate.
One Ed25519 keypair, yours forever. We never see the private half. Email is for delivery only — you can run MEOK without telling us a thing.
Sovereign for decisions, Creator for drafts, Companion for thinking out loud. Each one is the same mind in a different posture. Switch as the day changes.
MEOK remembers, signs, and reconciles in the background. Your AI gets more useful the longer you work with it — without ever sending your context anywhere you didn't choose.
MEOK isn't one product. It's a constellation — each surface solves a different moment in your day. Pick where to start.
The fastest on-ramp. One Ed25519 keypair, yours forever. No card. The AI follows wherever you go.
Sovereign, Guardian, Scout, Strategist, Creator, Companion, Sage. Seven ways of being the same mind.
SOVOS — Ed25519 signing, append-only ledger, offline-verifiable. The ground your sovereignty stands on.
