How it works

From your text to your ears in three steps

  1. 1

    Paste your text

    Articles, study notes, a script, a .txt import — anything you want to read. It's your content, not a fixed catalog.

  2. 2

    Pick a voice

    Choose from natural text-to-speech voices and fine-tune pronunciation for names and tricky terms.

  3. 3

    Press play & learn

    Read along as it highlights each line. Adjust speed, drop bookmarks, and listen offline anywhere.
