What is 싱크 (Sync / sync.so)?

Sync is a lip-sync tool that realistically remaps a person's mouth movements to match a different audio track, such as a dubbed or translated voice. Creators and marketers use it to polish dubbed videos, ads, and training content without awkward, mismatched lips. It offers both a browser studio and a developer API.

How to start in 5 minutes
