Everyone else monetizes your conversations. We encrypt them.
macOS 14+ · Apple silicon · transcription on the Neural Engine
Dictated on-device. The audio never left this Mac.
Privacy is built in, not a setting you have to find. The shots below are the actual app.
The AI industry runs on collecting your words. Ours runs on your Mac's Neural Engine — a state-of-the-art speech model executing on your own silicon, faster than a round-trip to anyone's cloud. Local AI isn't our compromise; it's our whole point. Nothing to harvest, nothing to train on, nothing to subpoena.
Not a policy promise — an architecture. The transcription model runs on your Mac's Neural Engine, and everything it hears stays on your disk, encrypted.
Hold Right Shift, speak, release — your words are typed where you're focused. Audio is processed on your Mac's Neural Engine, then overwritten in memory the moment it's transcribed — the app even blocks its own crash dumps, so nothing lingers to recover. On the free tier nothing you say ever leaves your Mac — the only time the app touches the network is a one-time download of the speech model on first launch.
Join a call and Privt Voice offers to transcribe it — both sides, labelled Me and Them, captured only from the call app. The finished transcript is sealed into your encrypted vault straight from memory — never written to disk in the clear.
Notes are sealed with keys protected by your Mac's Secure Enclave and unlocked with Touch ID. Even someone holding your files — including us — can't open them.
When your vault is created, you move your mouse — and that movement is built into your encryption keys. Unpredictable by anyone, unrepeatable by everyone.
Your Mac's hardware randomness, plus a layer that's yours.
Your meetings, your ideas, your thinking out loud — most dictation apps ship it to their servers and keep it in databases you'll never see, on terms they can change. Privt Voice encrypts every word end-to-end on your own machine: keys born in the Secure Enclave, content sealed with XChaCha20-Poly1305, zero knowledge by architecture. No copy exists that anyone else can decrypt — not thieves, not subpoenas, not us.
Your vault is protected by this Mac's Secure Enclave — and by a recovery phrase shown exactly once, generated on your device, never sent anywhere.
Privt Voice is the first of a family of tools built on Privt ID — an account that is a keyring we can't open. Every key is born on your devices; our servers hold only sealed copies. What we can't read, we can't lose, sell, or be forced to hand over.
A memorable code — two word-pairs, like ember-falcon iron-meadow. Enter it at our burn page from any browser, signed in or not, and every key we hold to your synced data is destroyed in one act — and each of your devices wipes itself the next time it comes online. Instant, no confirmation, no undo — we can't stop it, and once our infrastructure's short retention window ages out, nothing can bring it back. Built for the moment you hope never comes.
Lock Privt Voice and it becomes write-only: a meeting that ends while you're away still lands — encrypted to a key that only your next Touch ID can release. Capture never waits, and never sits readable.
Call capture is scoped to the meeting app alone — your music, videos and notifications never enter a transcript. Deleting is crypto-shredding: destroy the key, and the data is mathematically gone.
The same sentence, dictated and sent in Signal. Count the hands it passes through — and where Privt seals each one.
Everything in free, plus zero-knowledge backup and sync of your notes and meeting transcripts — across your devices.
