What sync.so is

sync. labs is an AI lipsync and visual dubbing platform. It generates mouth movement matched to audio for films, advertising and content, usable through a web studio or an API for pipeline work.

A distinctive feature is its watermarking technology: videos modified with the tool carry a traceable mark, and a verification step can check whether a video was altered.
