Every jump,
diagnosed by AI
AI-powered jump analysis for skaters, parents, and coaches. Upload a video for instant diagnosis and a personalized training plan — or bring your coaching expertise to the platform.
⭐ Every analysis is expert-reviewed before release — not raw AI output.
How it works
See how a real 2A (double Axel) fall gets diagnosed
A skater's parent uploaded this double Axel attempt after practice. The jump looked good — solid height, stable in the air — but the skater kept falling on landing. Within minutes, the AI pinpointed the root cause: not height, not balance, but rotation speed.
Computer vision extracts 33 body keypoints per frame; biomechanics turns them into repeatable measurements — not AI guesses, computed numbers.
Analysis #xxxx366e (2026-04-03). Same video, same numbers, every time.
From an early prototype build (March 2026). Today's live analysis surfaces fewer metrics — only the ones that map directly to a training action.
