Questions

Does it translate in real time?

Yes. Wuai captions a video and translates each line into your language as it plays, on your device (real-time translation). On a slower phone or computer, turn on Wait for captions, and the video waits a moment for them.

Can deaf and hard-of-hearing viewers use it?

Yes. Wuai writes captions for videos that have none, as they play, and the accurate Plus speech model is free with no limit. Automatic captions can get names and noisy speech wrong, and they only work on videos played in Wuai. Captions for deaf and hard-of-hearing viewers says what to expect.

Do my videos go to Wuai?
