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

French captions as a French video plays

Recorded in Wuai on Windows with Plus, the free speech model, not sped up: French speech with French captions, such as “sérieusement à la réorientation”, and no translation. Each line comes a moment after it is said; turn on Wait for captions and the video waits for it. Video: Trautmann, Catherine (fr) by Manuel Schneider, CC BY 3.0, on Wikimedia Commons.

A French video with English captions

Wuai on Windows: a French video with English captions, “I am a socialist and a member of the Socialist” over “je suis socialiste et membre du groupe au”.
Windows: je suis socialiste et membre du groupe au → I am a socialist and a member of the Socialist

Where

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