PTranslator

Private by design

Voice is personal data. PTranslator is built so that it never has to leave your computer.

Recognition, translation and speech all run locally. There is no account and no cloud call while it works.

Downloads are checked by SHA-256, redirects from https to http are refused, and archives are unpacked defensively.

One flag forbids all downloads; a missing model then fails with the command to install it instead of reaching out.

The code is Apache-2.0 and every component and model licence is listed. The speech model has usage restrictions you should read.

While the machine speaks, the microphone is muted so it does not hear itself; headphones avoid that gap altogether.

Small models make mistakes, and recognition errors carry into the translation. Short phrases can sound awkward.
