MotionClone turns a screen recording of any UI animation into working code. The problem: designers and apps ship motion as video, and engineers rebuild it by eye, guessing durations and spring values like "stiffness 300, damping 20", replaying it again and again until it feels close. It takes hours and rarely matches. MotionClone measures the motion instead. Drop in a short .mp4/.mov/.webm and it: 1. Finds every moving part and tracks it frame by frame. 2. Fits real damped-spring physics to each part (stiffness, damping, onset), with a fit quality score. 3. Generates a live, interactive clone driven by those springs. 4. Renders the clone next to your video in headless Chrome, scores the visual match, and sends the worst-matching frames back to be fixed, keeping the best version. "Refine again" continues from there. You can then fine-tune the feel with Snap Speed (stiffness) and Brake (damping) sliders that drive the live clone, verify the spring against the measured track, and export React (Framer Motion), SwiftUI, or CSS linear() code with the fitted constants.
