Can Wuai caption a video that has no captions?

Yes. Wuai listens to a video as it plays and writes captions on your phone or computer, in 100 spoken languages. If the video has captions of its own, Wuai shows those.

Are the captions free?

Yes. Captions in the video's own language are free with no limit, with the accurate Plus speech model. Wuai Pro, one payment, adds the most accurate Pro model and translation without limits.

How accurate are the captions?

Clear speech comes out well. Names, rare words, music, noise and people talking over each other can come out wrong, and captions do not say who is speaking or describe other sounds.

Does it work on Netflix, live streams or calls?

No. Wuai captions videos played in Wuai: websites you open in it, YouTube included, and your own video files. Protected videos such as Netflix, live streams, calls and other apps' sound are not captioned.

Captions for the videos that have none

Many videos online have no captions. Wuai listens to a video as it plays and writes captions on your phone or computer, so you can follow what is said. It is free, with no limit.

Captions appear as the video plays

Recorded in Wuai on Windows with Plus, the free speech model, not sped up: English speech with English captions, such as “focus is the industry committee.”, 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 (en) by Manuel Schneider, CC BY 3.0, on Wikimedia Commons.

Free, with no limit

Captions in the video's own language are free, made with Plus, the accurate speech model, for as long as you watch. No account, no subscription, no card. On a slower phone, Core is quicker; on a Mac or an iPhone, Apple's own speech is free too.

Wuai Pro, one payment, adds the most accurate Pro speech model, translation without limits, and clips without a watermark. Android and Windows get 30 free minutes of translated captions; translation on iPhone and Mac requires Pro.

Made to be read

Caption size: Small, Medium or Large.
Wait for captions: the video pauses a moment wherever its captions have not caught up, so no line is skipped, then plays on by itself.
Watch it again: captions made once show at once the next time you play the same video.
Keep them: captions are kept as subtitle files (.srt) you can open in other players.
Share a moment: clip the part you want with its captions drawn in.
In your language: 100 spoken languages become captions, and they can be translated into up to 95 (see each one).

Private by design

The video's speech is turned into captions on your device. Its sound is never sent to Wuai or anyone else. There are no Wuai accounts, no ads and no tracking (privacy).

What to expect

Automatic captions can be wrong. Clear speech comes out well; names, rare words, music, noise and people talking over each other can come out wrong. Check captions before you rely on them for something important.
Words, not sounds. Captions show what is said. They do not say who is speaking or describe other sounds, such as music or a door closing.
A moment behind. Each line appears shortly after it is said. Turn on Wait for captions to keep them in step.
For the most accurate captions, use Plus (free) or Pro, and a newer phone or computer.

Where it works, and where it does not

Wuai captions the videos it plays: websites you open in it, YouTube included, and your own video files. It does not caption protected videos (such as Netflix or Disney+), live streams, calls, or sound from other apps.

For those, your device may already help: Live Captions on Windows 11 and Live Caption on Android caption most sound your device plays, calls included, in fewer languages, and translate only on some devices. Wuai adds 100 spoken languages, translation on any device it runs on, and captions you can keep: compared with Windows Live Captions · compared with Android Live Caption.
