Watch VTuber Streams in Your Language, Live

Stop waiting days for a translated clip. Whisperr translates the stream as it happens, on whatever device you already watch on — floating subtitles over the stream on your phone, system audio capture on Mac and Windows, or tab capture in the browser. 100+ languages, about 0.2 seconds behind the stream.

  1. 1

    Open the stream on YouTube or Twitch

    Open the stream in the new tab, live or an archive, and leave it playing.

  2. 2

    Pick your languages

    Set the language the streamer speaks and the language you want to read. Tab capture is already selected.

  3. 3

    Press Record, then pick that tab

    Choose the stream's tab in the picker and tick Share tab audio. Translated subtitles appear here as the VTuber talks.

  4. 4

    Pop the subtitles out over the video

    Opens the subtitles in a small window that stays on top, so you can watch in the other tab and still read along.

When the tab picker opens, tick Share tab audio — without it there is no sound to translate.

On Mac or Windows, choose System audio in the Whisperr desktop app. It captures anything playing on the computer, including other apps.

Which way should you watch?

All three capture the stream audio on your own device, so the platform, the language and the paywall never matter. The difference is where the audio comes from and where the subtitles show up.

Watching on a TV or a console instead? Any of the three can listen through your microphone rather than capturing audio directly — lower fidelity than digital capture, but it works with hardware Whisperr cannot run on.

Whisperr and fan translation are not the same thing

Clip channels and translation communities are the heart of international VTuber fandom, and a machine cannot replace them: fan translators localize jokes, catch references, and add the context that makes a moment land. Nothing here is a substitute for that work.

What Whisperr covers is the gap in between — the hours of stream that never get clipped, the streamers whose audience is too small for a dedicated translator, and the live moment itself, before anyone has had time to subtitle it. Use it to follow the stream as it airs, and keep watching the clips for the parts worth rewatching.

If you want a fully free option, Google Translate and Papago handle short phrases well, but they translate one utterance at a time and have no live-stream capture, floating subtitles, or continuous flow — you would be pausing the stream to type. Whisperr has a free tier, and unlimited real-time use is a flat annual fee with no per-minute metering.

Are you the VTuber? Caption your own stream instead

This page is the viewer side. Captioning your own stream is a different setup, and it lives on its own page.

If you are the one streaming, none of the above applies to you — your viewers should not have to run anything to understand you. Whisperr Broadcast Mode gives your stream a transparent overlay URL that you drop into OBS as a browser source, and your speech is captioned and translated on screen for everyone watching, on every platform you stream to at once.

The overlay also parks a small QR code in a corner of the stream, so a fan who wants a language other than the burned-in one can scan it and read along on their own phone. The OBS page walks through the whole setup, including every overlay option.

Watch on your phone, your computer, or the web

Whisperr translates the stream audio, not the platform — so it works on YouTube, Twitch, or wherever your oshi goes live, including members-only streams. Pick whichever surface you are already watching on.

  1. 1

    On your phone — floating subtitles

    Open the Whisperr iOS or Android app, start transcription, turn on Floating Subtitles, then switch back to YouTube or Twitch. Translated captions float on top of the stream while you keep scrolling chat and reading superchats as normal.

  2. 2

    On your computer — system audio capture

    The Whisperr app for Mac and Windows captures your system audio, so it hears the stream exactly as it plays — clean digital audio with no room noise, which matters when a stream mixes game audio, BGM and voice.

  3. 3

    In the browser — tab capture

    The Whisperr Web App and Chrome Extension capture the stream tab directly, with nothing to install for the web version. Useful on a borrowed machine, a work laptop, or any computer where you would rather not install an app.

Whisperr review

“I love how easy Whisperr is to use and how it accurately understands and translates text and speech across different languages. It's so effective that even in scenarios where other tools might fail, Whisperr performs perfectly. Additionally, the ability to select languages for translation directly on a phone is fantastic. This feature helps us translate church services, ensuring everyone understands without missing anything important. The initial setup was straightforward, making it smooth to start using immediately.”

Top-Notch Speech Recognition and Flashcard-Style Translations for Fast Study

“Whisperr's speech recognition and translation quality are both top-notch, and better than similar tools I've tried so far. Beyond that, as a Japanese learner, I especially like how Whisperr displays each sentence and its translation almost like flashcards, with a text-to-speech button for each one. That setup makes studying feel fast and efficient, and it's easy to review sentence by sentence.”

Worth hundreds of thousands of yen

“The same performance as other conversation translation apps. Those charge by the minute, but this one is apparently a one-time purchase, so the value for money is outstanding. Compared with about five similar apps, this one is the best on both performance and price. I wonder whether it was made by a Japanese developer??”

Built for live streams

Keep up with the stream, not the clip channel

Fan translators do great work — but they publish hours or days later, and only for the moments they choose. This is the whole stream, live.

Live, not next week

Subtitles appear in about 0.2 seconds, so you follow jokes, reactions and superchat readings while they are actually happening.

Any streamer, any language

Japanese, Korean, Chinese, Indonesian and 100+ more — including streamers too small to have a clip channel translating them.

Floating subtitles

On iOS and Android the captions float over the streaming app, so you never leave the stream to read them.

Works on any platform

YouTube, Twitch, or a members-only stream — Whisperr translates the audio, so the platform and the paywall never matter.

Nothing needed from the streamer

Your oshi does not have to enable captions, add a plugin, or even know you are using it. Whisperr works from the audio already playing on your own device.

Handles stream audio

Built for the fast speech, slang and background game audio of a live stream, not clean studio narration.

Follow your favorite streamer, live

Real-time translated subtitles on any VTuber stream, in 100+ languages — free to try.

VTuber translation FAQ

Can I watch a Japanese VTuber stream with live English subtitles?+
Yes. Whisperr captures the stream audio — through floating subtitles on iOS and Android, browser tab capture on desktop, or your microphone — and shows live translated subtitles with about 0.2 seconds of latency.
How is this different from a translation clip channel?+
Clip channels translate selected moments hours or days later. Whisperr translates the whole stream while it is live, including the streams and streamers nobody clips.
Does it work on YouTube and Twitch?+
Both, and anywhere else a VTuber goes live. Whisperr translates the audio rather than integrating with a platform, so the platform never matters.
Does it work on members-only streams?+
Yes. If you can watch the stream, Whisperr can translate it — it works from the audio on your own device, so your membership access is all that is needed.
Can I use it on my phone while chatting?+
Yes. On iOS and Android the captions float on top of the streaming app, so you can read the translation and still use chat.
I am a VTuber — can I caption my stream for international fans?+
Yes, and it works the other way round: you add one browser source to OBS rather than asking viewers to run anything. Broadcast Mode gives you a transparent overlay URL that captions and translates your speech live in 100+ languages. The OBS live captions page has the full setup.
Which languages are supported?+
Over 100, including Japanese, Korean, Chinese, Indonesian and English in any direction.
Is it free?+
You can start for free. Unlimited real-time use is a low flat annual plan, with no per-minute metering and no per-language caps.
Do I have to install anything to watch on a computer?+
Not necessarily. The Whisperr Web App runs in the browser and captures the stream tab, so you can watch on a machine where you cannot install software. The Mac and Windows apps add system audio capture, which is the cleanest option when a stream mixes game audio and voice.
