Built so your voice
stays yours.
Your recordings live on your device. Everything that leaves it travels over encrypted connections, and only you can read what comes back.
How your data moves
Every arrow below is an encrypted connection. Cloud processing is off until you turn it on.
Your phone & watch
Recordings are saved here first
Stays on deviceType0 API
api.type0.io
MongoDB Atlas
Your text, never audio. Encrypted in transit and at rest.
OpenRouter
AI language models for titles, summaries and to-dos.
Speech recognition
Turns audio into text. Audio is passed through, not stored.
What keeps it safe
Encrypted in transit
The app, our API and our database all talk over SSL/TLS. Nothing travels in plain text.
Protected by Cloudflare
Our website and API run on Cloudflare, with DDoS protection built into its global network.
No passwords
You sign in with a one-time code sent to your email. There is no password to guess, reuse or leak.
Recordings stay on your device
Audio is saved on your phone and watch. We never store your recordings on our servers.
Never used for training
We never use your recordings or notes to train AI models. AI is used only to make your transcripts and summaries.
Only you can see it
Your notes belong to your account. Connected apps get access only after you approve them, and you can revoke it at any time.
Sign-in without a password
Email codes are short-lived and single-use, so there is nothing worth stealing.
