Every other AI is a rental in someone else's cloud (crossed out).
Meet the assistant that actually does the work — living on your Windows machine, not in someone's cloud. It sends your email, books your meetings, runs your smart home, prints, files, and remembers what you're building. Talk to it. Hand it real jobs. And every sensitive action is cryptographically signed, so you can prove it never did a thing it didn't tell you about.
PC Brain is the opposite bet: the model, the memory, the whole civilization of specialists — on your disk, under your control. The only time anything leaves is the moment you hand it a cloud key — and then only that one call goes out.
Corevana leads a crew of specialists that reason together before they act — a scout, a strategist, an archivist, a critic, a sentinel. They mature over years: they build memory, earn trust, keep their own case law. It doesn't reset every conversation. It grows into your AI.
The model and your data live on your Windows machine. No telemetry, no auto-update, no data sharing — you turn cloud on only if you want it.
Bitemporal memory that supersedes instead of forgetting. Day one, it already knows the work you were doing.
An open red-team fires poison, injection and collusion at its own defenses — and signs the result. Provable, not promised.
Counted live from the registry that ships in the product — not a marketing round-up:
Every sensitive action PC Brain takes is signed with a key on your machine. Here's a real one, signed live in your browser right now. Check it. Then change a single character and watch the proof shatter.
What just happened: your browser generated a key, signed the action, and verified it — with zero network. Change one byte and the signature fails, every time. On your machine PC Brain goes further: every action lands in an append-only ledger — SQLite triggers reject silent rewrites at the engine level, and the security audit log rejects deletes too — and you can run it with --trace-network to watch, yourself, that nothing leaves. This is how it becomes impossible to narrate an action it didn't take.
We use the word on purpose. A moat is ground a rival can't cross by shipping a lookalike next quarter — and every one below is dug into shipped code, running on your Windows machine, checkable by the meanest skeptic you can find. Offline.
Corevana cannot narrate an action it did not take. If the action didn't happen, the words never render — the honesty gate is enforced in code, fail-closed to silence, inside a one-click Windows product.
Proof: verify a portable proof bundle with zero network, take a swing at the standing “make it lie” bounty, or read the red-team report where it attacks its own defenses and signs the result.
Every sensitive action leaves a receipt co-signed by two independent keys — forging one means stealing both private keys, not sweet-talking a chatbot. And the receipts speak the world's proof languages: RFC 8785 canonical JSON, W3C Verifiable Credentials, OpenTelemetry spans.
Proof: check both signatures with standard offline tooling — no account, no server, no network connection required.
When something goes sideways, Corevana doesn't skim a transcript and guess. It replays the run from deterministic checkpoints and proves which agent did what — attribution as mathematics, not vibes.
Proof: run the same replay from the same checkpoints yourself and watch the identical verdict fall out.
Coordination, memory, voice, screen-sense, local inference — all behind a default-deny egress floor on your machine. Cloud is opt-in, per key you bring, and only that single call ever goes out.
Proof: pull the network cable and it keeps working; watch your own firewall log stay silent until the moment you opt a key in.
Your agents' memory is a signed security boundary, not a suggestion box. Every write is origin-signed, and unsigned or spoofed writes get dropped live — nobody plants thoughts in your civilization's head.
Proof: fire a spoofed memory write at it and watch it bounce; every accepted write carries an origin signature you can check.
Your specialists mature over years: signed DNA version chains, bitemporal trust, case law drawn from their own history, onboarding gates for rookies, retirement that hands insight to the next generation. You can't copy a decade — you have to live it.
Proof: every DNA version is a signed link in a chain — walk it offline from birth to today and verify each step.
