About sync.

at sync. we're making video as fluid and editable as a word document how much time would you save if you could *record every video in a single take?* no more re-recording yourself because you didn't like what you said, or how you said it. just shoot once, revise yourself to do exactly what you want, and post. that's all. this is the future of video: *AI modified >> AI generated* we're playing at the edge of science + fiction. our team is young, hungry, uniquely experienced, and advised by some of the greatest research minds + startup operators in the world. we're driven to solve impossible problems, impossibly fast. our founders are the original team behind the open sourced wav2lip, the most prolific lip-sync model to date w/ over 10k+ GitHub stars. we [1] train state-of-the-art generative models, [2] productize + host them for scale [3] grow virally through content [4] upsell into enterprise
