Motiscope

You can't describe an animation to an AI in words. "Make it bouncier" is not a spec. Motiscope solves this a different way: you give it a screen recording, it measures the actual motion (the beat, the easing, the transforms) with ffmpeg, and hands your coding agent a spec it can rebuild from. Output targets are GSAP, CSS, Framer Motion, and Lottie. Free, open source, runs locally.
