sync. is the world’s best zero-shot lip-sync engine that makes video as editable as text: drop in any video, script, or audio, and its new lipsync-2 model instantly retimes mouth movements with frame-level precision while preserving each speaker’s unique style—no training, cloning, or fine-tuning required.

A single, developer-friendly API lets creators dub content into any language, rewrite dialogue, or animate characters across live-action, animation, UGC and even game footage.

Record once, create forever.
