The Problem
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.
Your patterns are invisible
You know roughly how a session felt. But without data, you have no idea where your ball actually lands, how your strokes split, or what tendencies you repeat.
Coaching is expensive and rare
Quality coaching is $80–$150 an hour — and most players can only afford it occasionally. Between sessions, actionable feedback disappears completely.
You can't improve what you can't measure
Progress stalls when you rely on memory and instinct alone. Every elite sport now uses data — tennis at the recreational and competitive club level still doesn't.
Features
Everything you need to play smarter.
A complete computer vision pipeline that turns a single video file into a full analytics report — no setup, no sensors.
Computer Vision
Ball Tracking
Frame-by-frame YOLO-based detection traces every ball trajectory — bounce positions, speed changes, and rally sequences captured with sub-pixel accuracy.
Spatial Analysis
Court Heatmaps
Homography projection maps every ball landing and player position into court-space coordinates, generating density heatmaps that reveal patterns invisible to the naked eye.
Deep Learning
Stroke Classification
A temporal CNN classifies every detected shot as forehand, backhand, or serve using a rolling video window — giving you an exact stroke breakdown across the full match.
