Ukrainian and English captions, translated as the video plays

Wuai is a free app for Windows and Android that captions the videos you watch and translates the captions in real time, on your device. These screenshots show it turning Ukrainian speech into English captions and English speech into Ukrainian captions, on Windows and on Android.

Ukrainian captions as a Ukrainian video plays

Recorded in Wuai on Windows with Plus, the free speech model, not sped up: Ukrainian speech with Ukrainian captions, such as “що моя робота згодилася людям,”, and no translation. Each line comes a moment after it is said; turn on Wait for captions and the video waits for it.

Where

Wuai translates captions into Ukrainian on Windows and Android, and makes captions from Ukrainian speech on both. See every language.

Shot on November 1, 2026 with Wuai Pro switched on, the captions as Wuai made them. Other speech and translation models' captions can differ. Android and Windows translate 30 minutes of video for free; iPhone and Mac require Pro for translation.
