Filming Tips
- One single jump per clip — no combinations
- Film from the side (perpendicular to the jump direction)
- Keep the camera steady — avoid heavy shaking
- Make sure the full body is visible in frame
AI Analysis
After uploading, the AI automatically handles frame extraction, point selection, and bounding box confirmation. You just confirm the skater's position in the first frame to start the analysis.
Analysis Pipeline
AI-extracted key frame sequence
How long does it take?
Typically 1-2 minutes for the full analysis. You can leave the page and come back when it's done. Costs 4-7 Onion Coins depending on the jump type.
View Diagnosis Report
The diagnosis report is a comprehensive analysis of your skater's jump quality. The AI identifies key issues during takeoff, airtime, and landing, with a visual frame sequence showing each phase.
⭐Every diagnosis is expert-reviewed
After the AI generates a diagnosis, a verified coach or our founder coach reviews it to confirm accuracy before it reaches you. You never see raw, unverified AI output.
Jump Diagnosis
Double Lutz (2Lz)
AI Diagnosis Summary
Slight pre-rotation detected at takeoff, affecting rotation completion in the air. Recommend core stability drills at takeoff and ensuring a clean edge at the launch point.
💡 Use the frame viewer to step through the jump frame by frame and observe body posture details at each phase. Pinch-to-zoom is supported on mobile.
Personalized Training Plan
Based on the diagnosis, the AI generates a personalized one-week training plan. If your coach has assigned specific drills ("Coach's Pick"), those appear first with priority.
