sync.so

Video teams that need to change what someone says after the footage is already shot are the natural users of sync.so.

The sync.so tool is an AI lip sync generator and video editor that matches mouth movement to new audio, so you can swap or rewrite dialogue without a reshoot.

It does this without any training on the speaker, and it works on live-action footage, animated characters and AI-generated video.

The same service covers dubbing and translation.

You can clone a voice or use text-to-speech to produce the new audio, then let sync.so adjust the lips to fit.

That makes it a practical AI video translator for anyone localizing content into other languages.

Editing dialogue after it has been spoken is the headline use.

Developers get an API, so sync.so can sit inside your own product or pipeline instead of being used only by hand.

Pricing is handled through the company, so expect to contact them.

Because the results come from AI, plan to review each output for accuracy before you publish, especially for translated speech.
