CourtCheck turns raw match footage into the read coaches want. Ball tracking, heatmaps, stroke breakdown, and scouting reports. No rewinding a frame.
Tennis has always been played on instinct.
Every other major sport uses computer vision and analytics to train smarter. Tennis at the club and collegiate level is still flying blind.
Coaches scrub through hours of grainy recordings. Players replay points from memory. The answer to "what changed in the second set?" takes a Sunday to find.
CourtCheck closes that gap. Drop in the tape. Get the read.
Start with the tape. Nothing else.
Recording in, court out. No annotations yet. This is what every coach starts with after a recording. The next three stages are what CourtCheck adds.
Every shot, placed.
Bounce locations for every ball in the recording. Forehand, backhand, serve, volley. The view your coaching brain already uses, drawn for you in under fifteen minutes.
Where the player stood.
Each line is the gap between player and ball at contact. Short means squeezed. Long means reaching. The pattern that tells you why a stroke broke down late in the recording.
The pattern, called out.
Court coverage heatmap, plus the one line of plain English worth bringing to practice. Sequences surface only when they repeat across the recording.
Patterns you'd find watching the tape, in the time it takes to stretch.
CourtCheck reads recordings the way an experienced assistant coach watches it back. Every shot in context. Every pattern in plain English. Coaches save ~80 hours per season.
Patterns, in plain English.
"Lin wins 71% of service games when she opens with a slice." Plain prose, not dashboards full of numbers. We only surface patterns that show up across two or more recordings.
Shot maps, not spreadsheets.
Every bounce, every contact, every stroke type. Overlaid on a court tile. The view your coaching brain already uses.
From upload to first insight: 5 minutes.
