The browser reader
A PDF read aloud, without the file leaving your device.
Open a PDF in your browser and listen to it: the sentence you are hearing is highlighted on the page, and you can tap any paragraph to start there. The file itself never leaves your device: it is opened and read locally, and only the sentence being spoken is sent to us to turn into audio.
A free account is all it takes. No card, and 20 credits a day - about twenty minutes of listening - starting over every morning.
How it works
From the page to your headphones.

03Press play, move on
Brauo reads while you get on with the rest of your day.
Voices
Choose who reads to you.
17 Brauo Originals across 7 languages: made by us, self-hosted, and included in every plan at the same cost. Press play to hear a line.
German and Japanese are available too, on premium voices that spend credits faster, while we build our own.

≈ 300 ms
Brauo turns text into speech sentence by sentence in a few hundred milliseconds, and prefetches what comes next, so playback starts fast and never stalls.
