Captions in your language on any Android phone
Wuai is a free app for Windows and Android that captions the videos you watch on your phone and translates them into your language in real time.
Android's Live Caption captions up to 15 languages on a Pixel 6 or later and selected phones, fewer on older ones, and if a phone has no Live Caption, Google says to ask its maker (checked on November 1, 2026). Wuai brings its own speech and translation, whatever your phone's make: it hears 100 spoken languages and translates them into any of 91 (see each one), on your phone, for the videos of the websites you open in it, YouTube included, and video files.
Live Caption and Wuai
- Languages: Live Caption, up to 15, depending on the phone. Wuai hears 100 and translates into 91.
- Translation: on Pixel phones, Live Translate adds translation, and what it translates depends on the model. Wuai translates captions on any phone it runs on.
- What it captions: Live Caption, sound in most apps, calls included. Wuai, the videos you open in it.
- Where it is done: both hear on your phone, and Wuai translates there too.
- Only in Wuai: the line as spoken with its translation under it, captions kept as .srt files, and a moment clipped with its captions drawn in.
How to
- Get Wuai for Android and open the video in it: go to its website, or paste its link. A video file works too.
- Tap CC.
- In caption settings, choose your language under Translate to.
- Play the video: the translated captions appear as it plays. Under Show, choose your language, the line as spoken, or both.
Free, or Pro
Captions are free, with the accurate Plus speech model and no limit. Each Android phone also 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 and adds the Pro speech model, the most accurate (it needs 4 GB of memory or more on a phone).
