Your voice, not synthetic
You record each line yourself. The performance is yours — not an AI clone of a voice you picked from a dropdown.

How RythmoClip differs from AI dubbing tools
Tools like Rask.ai, ElevenLabs, or HeyGen replace every voice with synthetic audio. They are useful if you need a full language pass with no human in the loop. But the result sounds like a machine — and it replaces voices you never wanted to touch.
RythmoClip does the opposite. You record yourself. The AI only helps with transcription — finding the lines and timing them. The performance is yours. And every character you did not pick keeps their original voice in the export.
If you want to hear a real voice on a specific character, and keep everything else intact, that is exactly what RythmoClip is built for.
Who uses RythmoClip for online dubbing
Fan dubbers who want to hear their voice in a film scene without rebuilding the whole track. Voice actors practising lipsync on real material. Creators dubbing a clip into their language for social media. Students learning post-sync technique without a studio.
The common thread: they want a real performance on a specific role, and they want the rest of the scene to stay as it was.

Frequently asked questions
Do I need to install anything?
No. RythmoClip runs entirely in the browser on Mac, Windows, Linux, and Chromebook. No driver, no plugin.
Can I dub only one character?
Yes. Select just that character in the casting step. Every other voice stays in the original mix.
Is the dubbing AI or my own voice?
Your own voice. The AI only transcribes the lines and times them. You record every take yourself.
What file formats are supported?
MP4, MKV, and MOV up to 2 GB. If you have another format, use the free Convert to MP4 tool first.
Can I do multiple takes on the same line?
Yes. Record a line as many times as you want. Keep the best take before exporting.
Can several people collaborate on the same scene?
Yes. Each person logs in and records their assigned characters. The export combines all takes into one file.
