Five steps, and only one of them uploads anything.
From picking a file to exporting the finished video, here is the whole path — including exactly where your data goes.
Choose your video
Pick an MP4 or WebM from your machine. It opens in the browser and stays there — nothing is uploaded at this step.
We extract only the audio
The browser demuxes the audio track and uploads that alone. A 2 GB lecture becomes roughly a 19 MB upload.
Pick your languages
Select any of our 14 languages, dubbing in any direction — one pass, one price shown up front, every language you ticked.
Same-voice dubbing runs
Transcription, translation and same-voice synthesis produce a dubbed MP3 plus subtitles for each language.
Preview & export locally
Play the dub against your muted video, then export a finished MP4 or WebM on your own machine — free, every time.
Your video never leaves your device.
Source video frames and the file itself never leave the browser. Only the extracted audio, transcripts, dubbed audio, subtitles and your account and billing metadata are processed in the cloud.
Your device
2 GB video
Decoded, previewed and exported right here in the browser.
Our cloud
Audio in, dubs out
Transcript, translation, same-voice audio and subtitles. Nothing visual, ever.
Automatic deletion
Trial media is deleted after 24 hours, paid media after 7 days — or immediately, whenever you ask.
No training on your content
Your audio, transcripts and voice are never used to train models. Not ours, not anyone else’s.
Price shown before processing
You see the exact minute count and cost before a single credit is spent. No surprise metering.
Hear the same voice change language
One recording, two of our 14 languages. Listen for the timbre staying put while the language changes.

1 output minute = 1 minute of source into 1 language. Local preview & export are always free.
What this does not do — yet.
Better to read it here than to discover it after paying. Every one of these is a real constraint of the current pipeline.
- Browsers
- Desktop Chrome and Edge only. The local pipeline needs WebCodecs, so mobile and Safari are not supported yet.
- Formats
- MP4 with H.264 video and AAC or MP3 audio, or WebM with VP8/VP9 video and Opus or Vorbis audio.
- Size & length
- Up to 2 GB and up to 20 minutes per video.
- Speakers
- One primary speaker with reasonably clean speech. Overlapping voices and heavy noise degrade the result.
- Output audio
- Voice only. Background music and sound effects from the original mix are not preserved in the dub.
- Lip sync
- None. We produce audio and subtitles — the picture is never re-timed or altered.
- Languages
- 14 languages, any direction: English, Spanish, Portuguese, French, German, Italian, Russian, Chinese, Japanese, Korean, Indonesian, Thai, Malay and Vietnamese. Quality is strongest on our most-tested pairs; every dub is previewable before you export.
Be first when dubbing opens.
We are onboarding creators in small batches while we tune quality per language pair. Leave your email and we will write when it is your turn — nothing else, ever.
One email when your invite is ready. No newsletter, no sharing.
Questions we get asked first
Still unsure about something? Write to us — we answer as the people who built it.
Is my video uploaded?
No. Your browser opens the file from your disk and extracts only the audio track — that extracted audio is the single thing that reaches our servers. The video frames and the file itself never leave your device, which is also why the preview and the final export both run locally.
How does same-voice dubbing work, and do I need consent?
We transcribe the uploaded audio, translate the transcript, then synthesise speech that keeps the original speaker’s timbre. You must be the speaker or hold the speaker’s written permission. Cloning a voice without consent is not allowed and results in account termination.
What do I actually download?
For every language you selected: a dubbed MP3 and a matching SRT subtitle file. You can also export a finished MP4 or WebM straight from the browser — the new audio is muxed with your untouched video by packet copy, so the picture is bit-identical and the export costs nothing.
Why not just use YouTube’s automatic dubbing?
YouTube’s dubbing only exists inside YouTube. Our outputs are portable files you own, so they work in course platforms, podcast feeds, ad accounts, LinkedIn, or a separate localized upload with your own thumbnail. And the audio carries your voice rather than a generic stock one.
What happens with refunds and failed jobs?
Credits are reserved when a job starts and released back to your balance automatically if it fails, so you are never charged for output you did not receive. For anything else, email us within 14 days of the charge and we will sort it out.
Do you disclose that the audio is AI-generated?
Yes. Dubbed audio is AI-generated and we say so plainly: outputs carry AI-generation marking and metadata, and we ask you to disclose it wherever the platform you publish on requires a disclosure.
