Hi Product Hunt 👋

I’m Zoe, a PM at ViiTor—and also a K-pop and VTuber fan.

I started caring about this problem after missing too many great moments in livestreams. Fan-made subtitles often didn’t arrive until the next day, while general translation tools struggled with fast speech, slang, and the way people actually talk on live video.

That’s why we built ViiTor Translate: to help you understand those moments as they happen.

Turn on Floating Subtitles, choose your languages, and ViiTor displays translated captions directly over the video or livestream you’re watching. It works with YouTube, TikTok, Bilibili, and other supported platforms.

The part I’m most excited about is context. ViiTor uses our own speech technology to process live audio, while Fan Dictionary lets users add fandom-specific names, phrases, and community terms that ordinary translators often miss.

Our goal is to make live translation feel less literal and more aware of what people actually mean.

K-pop and VTuber streams are some of our favorite use cases, but ViiTor can also help with international videos, meetings, classes, and face-to-face conversations.

ViiTor is available on iOS and Android, supports 20+ languages, and is free to try.

For our Product Hunt launch, we’ve also introduced lower-latency subtitles and a new dual-language mode ✨ You can follow translations faster while keeping the original captions visible.

I’d really love to hear what you’d try it with first:

Which livestream, creator, or recurring translation mistake should we test next?
