How it works

  1. Open the app

    Open app.prontei.com in a desktop browser. There’s nothing to install and no account to create.

  2. Choose the speech model

    Automatic (25 languages) or Brazilian Portuguese (dedicated model). The automatic model recognizes 25 European languages on its own.

  3. Allow the model download

    The first time, Prontei asks before downloading: 678 MB or 754 MB, depending on your computer. It downloads once and stays in this browser.

  4. Drop the file and read the text

    The text comes with timestamps. Listen from any point, fix what you need and download it as TXT, SRT, VTT or JSON.

Before you start

  • Computer only. This first version is made for desktop browsers, not phones or tablets. We’ve tested transcription in Chrome.
  • Model download. 678 MB or 754 MB, once per browser, so leave about 1 GB free. The app and the extension each download their own copy.
  • Languages. 25 European languages with the automatic model, and a dedicated model for Brazilian Portuguese. Other languages aren’t supported yet.
  • File size. Up to 1 GB and 6 hours per file. If your browser can’t read a format, Prontei tells you.
  • Speed. Prontei transcribes faster when your browser can use the graphics card. Without it, Prontei uses the processor, which is slower. Test this browser.
  • One copy. Transcripts stay only in this browser. If you clear this site’s data, any you haven’t exported are lost.
  • Accuracy. Transcription can get words wrong. Check the text before using it for something important.

Your files stay on your computer, unless you choose the cloud.

Your files and transcripts stay on your computer, and we don’t receive any of it. The exception is a file you choose to send to the cloud, after a notice that names who receives it.

Usage data is on by default, and you can turn it off at any time in the app. It never includes files, audio or transcripts. Read the app’s privacy policy.
