What is CozyClay?

CozyClay runs in a web tab and lets you build a 3-D blockout of a scene, place sets, move characters, set camera cuts, then exports a reference frame, short clip and prompt for an AI video model. The AI generates the final footage based on that pre-visualization, saving costly trial-and-error.

Who it is for

Filmmakers and game devs can prototype shots cheaply and avoid paying for failed AI video renders.
