Translated captions on Windows, on any PC and in your language

Wuai is a free app for Windows and Android that captions the videos you watch and translates them into your language in real time, on any Windows PC.

Windows 11's Live Captions translates only on a Copilot+ PC running Windows 11, version 24H2 or later, and only into English or Chinese (Simplified), Microsoft says (checked on November 1, 2026). Wuai needs no Copilot+ PC: it hears 100 spoken languages and translates them into up to 95 (see each one), on your computer, for the videos of the websites you open in it, YouTube included, and the video files you add.
