LiveTranslate — Friskription for Chrome
Live translated subtitles for Twitch, YouTube Live, and anything playing in your browser — even streams with no captions at all.
30 free minutes every week · no AI accounts needed · or bring your own API keys
Interactive demo — a simulation, so the sign-in is fake and nothing leaves this page. Press Start, then drag and restyle the subtitles.
Real speech-to-text
Other “subtitle translators” need a caption track to translate. Twitch has none.
No caption track to read
It can only translate subtitles that already exist — so on Twitch, or any video without CC, it does nothing at all.
次のマップ、ちょっと怖いかも…みんな一緒に行こう？
The next map might be a little scary… come with me, everyone?
It listens to the tab's actual audio, transcribes it, and translates that. If the tab makes sound, it can be subtitled.
How it works
No API keys, no card. Thirty free minutes are waiting.
このボス、まじで強すぎるんだけど…
This boss is seriously way too strong…
It listens to the audio itself. No caption track needed, ever.
I'm reading all the chat messages — thank you!
Drag it, restyle it, and save the transcript as TXT, SRT or VTT.
Designed for watching, not just reading
New: Sync presets pre-process the audio so the subtitle is already on screen as the words are spoken — the closest thing to true realtime.
Twitch, YouTube, lectures, podcasts, news — not tied to any one site.
Translate into any of fifteen languages, with the spoken language detected for you.
Waits for a natural pause so translations read as whole thoughts. Quick, Balanced, and Precise presets.
Streaming transcription shows the sentence forming as it is spoken, then swaps in the finished translation. Uses more of your provider quota.
Drag it anywhere, resize it, restyle it, toggle the original line — only the latest lines stay on screen.
Drop in an MP4, MP3 or WAV and watch it with live subtitles — or turn it into an SRT or VTT file to keep.
A glossary locks your preferred spellings for streamers, characters, and recurring terms.
Collabs and interviews keep voices apart in the subtitles.
Each site remembers the timing and language you chose for it.
Start, pause, hide, clear, and cycle target languages from the keyboard.
Save what you watched as TXT, SRT, or VTT.
Under the hood
Step one — hearing it right
Every subtitle starts as a transcript, so this sets the ceiling for everything after it.
Published benchmarks, August 2026. Lower is better. Every engine scores worse on a noisy live stream than on a benchmark clip.
Step two — saying it well
Read a line that arrives half-finished
Spell a name the same way an hour later
Answer in under a second, a dozen times a minute
New — Sync mode
Every live translator is a little late — it has to hear a line before it can translate it. Sync mode pre-processes the audio instead, so the subtitle is ready before the line reaches you. You read it as you hear it, not after it.
Why all three trail the audio: a translator that leaves your playback untouched cannot translate a line before it has heard it, so how long it waits is a straight trade of delay against quality — wait less and lines arrive sooner but choppier, wait more and they read better but land later. That trade-off is a well-documented constraint in simultaneous-translation research, and the three approaches above are the usual places to sit on it. Live Sync steps off the curve instead of picking a spot on it.
Short, quick phrasing so each line lands as the words are spoken. Pick it once and you are done.
Waits a beat longer so lines read as fuller sentences instead of fragments.
Picture and sound stay together, so the subtitle never runs ahead of the face on screen.
Sync presets play a touch behind live and do more work on your machine, so they use more CPU and battery than the standard ones — and they cannot run on DRM-protected sites like Netflix. Prefer to leave playback completely untouched? Quick, Balanced, and Precise work exactly as before.

No. Twitch has no automatic captions and no translation for viewers — captions appear only if the streamer runs special captioning software, which most don’t. Friskription works entirely on your side of the screen, so it doesn’t depend on the streamer at all.
Yes — that’s the whole point. It transcribes the actual audio of the tab, so no caption track is ever needed. Twitch, YouTube Live, Kick, uncaptioned VODs, lectures: if the tab plays sound, it can be subtitled.
Yes. Japanese and Korean streams are the most popular use. The glossary keeps streamer and character names spelled the way the community spells them, and speaker labels keep collab streams readable.
Fifteen: English, Japanese, Chinese, Korean, Spanish, French, German, Portuguese, Russian, Arabic, Hindi, Italian, Vietnamese, Thai and Indonesian. The spoken language is detected for you, so there is usually nothing to set.
Chrome’s Live Caption supports a limited set of source languages, renders into a small fixed box, and translates with basic machine translation. Friskription uses best-in-class speech recognition plus AI translation that understands context, keeps names consistent, and draws subtitles as a styled overlay you can move and resize on the video itself.
No. Audio is processed only while you have translation running and is never stored. With your own API keys it goes straight from your browser to your provider and never touches our servers. See the privacy policy.
No analytics, no browsing history, no stored audio. Payments happen on PayPal’s or Stripe’s own pages. With your own keys, nothing ever touches our servers.
The privacy policy and terms of service are available in English only.
