Q: Does the recording leave my iPhone?

No. The audio is kept on your device and is transcribed there by iOS. Only the transcript’s text is sent, with Premium, when you ask for a summary or a question, and our server does not store it.

Q: Can I use a voice memo or an audio file?

Yes. Open a voice memo or an audio file from Files, and it is transcribed the same way.

How it works

Press record.
That’s the hard part.

The transcript is written on your iPhone as the words are said. The audio never leaves it.

Record, or open a file

Tap Record on the home screen, or open a voice memo or an audio file. Mark a moment with a star while it runs.

Read along

The words appear as they’re spoken, with the time. Lock the screen; the timer stays in a Live Activity.
