Wuai

How it works

Watch Wuai caption a film and translate it in real time as it plays. Then clip a moment with its captions drawn in, share it, post it and save it, on Windows and Android.

Captions and translation, in real time

Wuai uses the video's own captions, or makes them from its speech on your device, and translates them as the video plays.

  1. Open the video: go to its site in Wuai, or paste its link.
  2. Turn on captions: Captions on Windows, CC on Android.
  3. Turn on Translate captions, pick a Translation model, then choose your language under Translate to.
Windows: English, translated into Spanish
Android: into Chinese

Made with Wuai's best models: Pro's speech model (Whisper large-v3-turbo), and on Windows Pro's translation model (Qwen). Translating is free for 30 minutes on Android and Windows; on iPhone and Mac it requires Pro. Pro's models come with Pro.

Clip

Keep just the moment you want, with its captions drawn into the picture.

  1. Choose Clip and set where it starts and ends: Start and End under the video on Windows; drag the two ends on Android.
  2. Tick Draw into saved video, then choose Save clip.
  3. The clip plays from the Library, captions and all.
Windows: set it, save it, play it
Android: drag the two ends

Post & Share

Get the clip to your audience: Windows posts it to several sites for you; Android sends it to the app they're on.

  1. On Windows, choose Post beside the clip, write the text once (and a title for YouTube) and tick the sites.
  2. Choose Post to 4: Wuai shows what goes to each site, and posts only when you choose Post now, on each site's own page, where you're signed in.
  3. On Android, choose Share on the saved clip and pick the app.
Windows: Post, up to the check before posting. Nothing was posted.
Android: Share, pick an app

Save

Keep the whole video, or only its sound.

  1. Choose Save: Wuai keeps the whole video, up to the quality you choose.
  2. The arrow beside Save has more: Save audio for only the sound, Save as… and Quality.
Windows: the whole film, captions drawn in
Android: Save audio

Only save and share videos you made or have the right to use.
