The Local engine processes everything in the browser — no upload, ever.

Other "free" tools upload your video

Private browser dubbing — FAQ
Is browser video dubbing really free?
Yes. The Local engine runs entirely in your browser and is free and unlimited — no card required. Paid cloud plans add professional voices and speaker diarization, starting at €14.90/month.
Does my video get uploaded to a server?
No. With the Local engine your video, subtitles and dubbed audio stay on your device (in the browser's storage). Nothing is uploaded — that's what makes it genuinely private, unlike "free" tools that process your video on their own servers.
Do I need an account to dub a video privately?
You can run the free in-browser dub without sending your video anywhere. An account unlocks the cloud engine and saved history.
Which languages can I dub into?
30+ languages. See the full list on the languages hub and pick the one you need.
