About sync. labs

sync. labs, at sync.so, makes AI lipsync and visual dubbing tools for filmmakers and creators. You give it a video or an image and new audio or a script, and it generates a video with the lips matched to the new performance.

Its models are sync-3, lipsync-2-pro and react-1. sync-3 is the default for all users. The sync-3 documentation lists 95+ languages, 4K native face output, and video or image input, and sync. labs says the model handles close-ups, extreme angles and objects in front of the face.

You can use it in a web Studio with Lite, Assistant and Advanced modes, through an API, in plugins for Premiere Pro and DaVinci Resolve, and as a ComfyUI node. There's an official ChatGPT plugin with an embedded Studio, and an MCP server for connecting your own agent. Work from connected clients such as ChatGPT, Claude and Gemini shows up in Studio history.

Translate & Dub translates the speech in a video and lip-syncs the result, with regional choices such as Spanish for Argentina, Chile, Spain and Mexico. Edit Dialogue changes specific words while keeping the original speaker's voice.

sync. labs also has a verification tool: upload a video and it checks whether the video was modified with its technology, using the company's own watermarking.
