CourtCheck tracks every shot, bounce, and stroke in a match recording, then writes up what a coach would notice. Ball tracking, court maps, stroke breakdown, and a written report.

The state of the game

Coaches still review tennis from memory.

College tennis has the footage and none of the tracking. Coaches scrub through hours of recordings; players replay points from memory. The answer to "what changed in the second set?" takes a Sunday to find.

CourtCheck answers it from the recording.

Stage 01 · The court

Start with the recording.

The court appears without annotations first. The next three stages add bounce locations, contact spacing, and coverage from the recording.

Stage 02 · Shot map

Every bounce on the court.

Bounce locations are plotted on the court and labeled forehand, backhand, or serve. Processing takes about 15 minutes.

Stage 03 · Spacing

Where the player stood.

Each line shows the distance between player and ball at contact. Short lines mark squeezed contact; long lines mark reaching. Compare contact spacing as the recording progresses.

Stage 04 · Coverage

What repeats.

The heatmap shows where the player spent time. The report describes sequences that repeat across the recording.
