Sintesi

Record. Transcribe. Summarise.
All on your phone. No account, no server, and your notes never leave it.

How it works

  1. Record, or receive a voice message. Press the big circle and talk, or share an audio someone sent you straight to the app.
  2. Sintesi transcribes it, on the device. The AI models run on your phone. No network needed.
  3. Choose how to rewrite it. From the same text: a clean note, a list, meeting minutes, a summary, or a message to send.

Why on-device

A voice message is not a neutral thing to hand to a server: it carries a voice, a name, a place, a mood. Sintesi never sends it anywhere — not because we promise, but because there is nowhere for it to go.

Before you install

The app downloads about 3 GB of AI models the first time you set it up, over Wi-Fi. That is what makes everything else work without a network. Audio files imported from outside the app can be up to 30 minutes long; recordings made in Sintesi have no such limit.
