Description
An AI coach for racket sports — table tennis, tennis, badminton, pickleball. It writes your training week like a pro would, reads ten seconds of phone film frame by frame and comes back with what's working, the one fix that matters and the drills to fix it, and keeps your real coach in the loop: they review clips, propose lessons and book you. Reminders and notifications for every session. Real reads with their frames at courtrally.fun/sample. Free to start; packs never expire.

Could you build this?
Partial The mobile UI, training plan generator, and coach messaging features are easily vibe-coded, but analyzing high-speed racket swing biomechanics frame-by-frame from consumer smartphone video requires specialized computer vision engineering.
What it would actually take: A working system requires an on-device or cloud computer vision pipeline using models like YOLO-Pose or MediaPipe fine-tuned on racket sport kinematics to track limb joints, racket path, and contact point. Heuristic algorithms and sports science models must segment the swing phases (preparation, acceleration, impact, follow-through) to detect mechanical flaws. Building this requires expertise in computer vision, video temporal alignment, and biomechanical analysis.
