Zipperline: Ski Video Analysis

Zipperline turns your skiing and snowboarding videos into clear, actionable feedback. Upload a clip from the slopes and let the app analyze your movement frame by frame.
Using AI-powered pose detection, Zipperline identifies your body's key points and tracks how you move through each turn. It measures joint angles, body position, and posture, then displays them visually over your video so you can see exactly what's happening in your technique.
Create a standalone analysis of your own run, or build a side-by-side comparison between your video and a benchmark to see exactly where your technique differs. Zipperline gives you a score that tells you how close you are to the benchmark, so you can measure your progress with real numbers.
