Free tools / AI video dubbing

Dub a video into another language with AI

Upload once, publish in another language. AI transcribes, translates, speaks each sentence where it was said, and lowers the original voice underneath.

Included in every paid plan · The editor itself is free
How it works

Three steps, a couple of minutes

Drop in the video

AI listens and writes the transcript, or reuses one you already made.

Pick the language and a voice

Natural English and Spanish voices with previews; basic voices for French, Chinese, Japanese and Korean.

Review and export

Every dubbed line is an audio clip you can nudge, re-time or replace. Add translated captions, then export.

Why it works

Why use CutLuma for this

Timed to the original

Each sentence starts where the speaker started it, may run into the next pause, and is only hurried up to 1.25× before it is trimmed.

Original stays, quietly

Keep the original voice ducked under the dub for authenticity, or mute it entirely.

One undo

The whole dub is one step: Ctrl+Z or "Remove the dub" restores the original sound.
