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

Where

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