Polish 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 Polish speech into English captions and English speech into Polish captions, on Windows and on Android.

Polish captions as a Polish video plays

Recorded in Wuai on Windows with Plus, the free speech model, not sped up: Polish speech with Polish captions, such as “Gdyż może ze względu na naszą historię,”, and no translation. Each line comes a moment after it is said; turn on Wait for captions and the video waits for it. Video: WIKITONGUES- Marta Speaking Polish by Wikitongues, CC BY 3.0, on Wikimedia Commons.

Wuai on Windows: a Polish video with English captions, “Currently, I live and study in Kaunas.” over “Obecnie mieszkam i studiuję w Kownie.”.

Where

Wuai translates captions into Polish on Windows and Android, and makes captions from Polish 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.
