Listen After You Go Offline

Once Speak and a voice are ready, KeyVox can turn copied text into speech on your iPhone without sending it to an online voice service.

You may still need the internet to load the original webpage, receive a new message, or get a new answer from ChatGPT or Claude. KeyVox handles the listening step after the text is already on your phone.

Try Speak for Free and Replay Anytime

KeyVox Speak includes two free new readings each day. If you want unlimited readings, Speak has its own optional one-time unlock.

Replaying your most recent completed audio does not use another free reading. KeyVox saves that latest text and audio locally on your iPhone so you can pause, resume, or listen again.

Good to Know Before You Go Offline

  • KeyVox Speak reads copied text on your iPhone.
  • Finish the first Speak and voice downloads while you have internet access.
  • A long passage can take a little longer to prepare than a short message.
  • New text from an online app still depends on that app’s connection.
  • Apple handles the optional one-time purchase and restoration.
