Sync.so (AI Lip Sync) – Sync.
so is an AI tool that lets creators modify or generate spoken content in a video by seamlessly adjusting the speaker’s lip movements. In practice, Sync.
so enables you to make someone in a video appear to say something they didn’t originally say – all without manual animation or re-recording. For example, if you have a marketing video but need to change a line of dialogue, you could use Sync.so: upload the video, input the new script or audio, and the AI will alter the speaker’s mouth motion to match the new speech, producing a revised video where the change is virtually undetectable. This technology works similarly to deepfake lip-sync methods, analyzing facial expressions and predicting how the lips and jaw should move for each syllable. Sync.so likely also offers voice cloning or high-quality text-to-speech so the new audio can sound like the original speaker (or you can supply your own audio track). The interface is user-friendly – perhaps you highlight the segment of video and type the new line, then let the AI handle the rest. It’s invaluable for content localization (dubbing videos into other languages while keeping the speaker’s visual appeal) and post-production fixes (correcting errors or updating outdated info in videos). Sync.so exemplifies how AI can grant fine-grained control in video editing: creators can “edit the dialogue” of videos as easily as editing text, while maintaining a realistic visual result. It’s a powerful tool that, when used responsibly, can save time and resources in video production and open up creative possibilities (like humorous edits or mashups) with precision.
