How message and voice translation works

A message written in one language arrives in another. The translation is made in the cloud, after your phone has decrypted the message.

What it does for you

  • Messages appear in your language, in any of 92 languages, with the original still visible.
  • In a group, each member reads in their own language.
  • Voice messages come with their text and a spoken translation.

How it works

A message arrives end-to-end encrypted. When it is in a language you do not read and cloud translation is on, your phone decrypts it and sends the text to AiThao’s translation service, which asks a cloud translation model and, if that one is unavailable, a second one. The translation comes back to your phone; AiThao does not store it.

For a voice message, the recording is transcribed, translated and spoken in a synthetic voice when the listener’s phone asks for it.

Questions

Can I turn message translation off?

Yes, in Settings → Translation. Messages then stay as they were written, and nothing is sent for translation.

Does AiThao keep the translations?

No. The translation service returns the translation to the phone that asked for it and does not store it.
