Watch videos with captions in your language

Wuai is a free app for Windows and Android that puts captions in your language on the videos you watch, translated in real time as they play.

It translates a video's own captions or subtitles into up to 95 languages. When a video has none, Wuai makes them from what is said (100 spoken languages) and translates those. It works on the videos of the websites you open in Wuai, YouTube included, and on video files you add. Captions and translation are made on your device: your videos are not sent to Wuai.

How to

  1. Open the video in Wuai: go to its website, or paste its link. A video file works too.
  2. Turn on captions: Captions beside the video on Windows, CC on Android.
  3. In caption settings, choose your language under Translate to.
  4. Under Show, choose your language, the line as spoken, or both.

Languages

Wuai hears 100 spoken languages (Cantonese with the Pro speech model) and translates captions into up to 95 languages, depending on your device: see each one.

Free, or Pro

Each Android phone and Windows computer translates 30 minutes of video for free, with no account and no card. Wuai Pro (US$29.90, one payment, no subscription) translates without limits, adds Pro translation on your computer, and translates into up to 5 languages at once there.

Questions

Does it work on YouTube? Yes. Wuai captions the videos of the websites you open in it, YouTube included, and uses a video's own captions when it has them.

Does it translate as the video plays? Yes, in real time: each line is translated as the video plays. See real-time translation.

What if the video has no captions? Wuai makes them from the speech, on your device, then translates them. See captions for a video that has none.

Can I see the original line too? Yes: tick your language and Original under Show. See two captions at once.

Can I keep the translated captions? Clip a moment with them drawn into the picture (clip with captions). Export .srt… keeps them as subtitle files, one for each language.

Do my videos leave my device? No. There are no Wuai accounts, no ads and no tracking. Privacy says exactly what leaves your device.
