What it does

Books, PDFs and the web

Open an EPUB, a PDF, a Word file or a link, or pick from 70,000 free books. The sentence being read is highlighted, and you can pick up where you left off.

Read like a narrator

A small model plans each sentence's pace, pitch and pauses the way audiobook narrators read, so a chapter sounds like one performance, not a list of sentences.

Anything you select

Select text in any app and press a shortcut (Mac) or tap Share (Android). Or have the screen in front of you read aloud.

Messages and calls, out loud

Hear WhatsApp, Messages, Slack and calls as they arrive, each in a voice that fits. On the Mac it also tells you when a coding task or a long build finishes, and when your battery runs low while you work.

200 voices, your style

Pick a voice, a style and a speed, and fine-tune pitch and expressiveness. On the Mac, save any book as an audio file for your phone or the car.

Private by design

The voice runs entirely on your device: no account, no internet needed to speak, and nothing you read is sent anywhere.
