AI Video Dubbing
Turn one clip into every market. FATTLY's AI video dubbing keeps the same person on screen, swaps the language and re-syncs their lips to the new audio — so a Polish ad becomes English, German, Spanish or French without reshooting. Upload a short clip, pick the target language and voice, and download a dubbed video with natural lip-sync, right in your browser.
Why dub with FATTLY
Same speaker, new language

AI video dubbing FAQ
How does AI video dubbing work?
Upload a short clip, choose the language and voice you want, and FATTLY re-voices the speech and re-syncs the speaker's lips to the new audio. You get a dubbed MP4 with natural mouth movements, all in your browser — no editing software needed.
Which languages can I dub into?
You can localise a clip into languages including English, Polish, German, Spanish and French, choosing a voice for each. That turns one video into several market-ready versions instead of filming again for every language.
How long can the clip be?
Dubbing works best on short clips — ideal for ads, hooks, product demos and social videos. Keep segments short and clear for the cleanest lip-sync, and split a longer video into parts if needed.
How much does it cost? Is it free to try?
You start with 10 free credits and no card, so you can dub a clip before paying anything. After that FATTLY is pay-per-credit and your credits never expire; a subscription is optional.
Can I use dubbed videos commercially?
Yes, within the Terms. Dub your own footage or clips you hold the rights to, and use the result in ads, social posts and your store. Only dub content you are allowed to use.
Can I dub from Polish to English, or between other languages?
Yes. Dubbing is built for cross-language localisation — dub Polish into English, German, Spanish or French and vice versa, picking a voice for the target language. It's ideal for Polish creators and shops reaching audiences abroad.
