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.
