Film a shot.
Get coached by AI.
OnCourtAI analyses your forehand, backhand, serve and volley, plus nine padel strokes, from a single phone video. Every stroke scored out of 100, what to fix, and the drills to fix it.
Three steps to better strokes
No sensors, no special camera. Just the phone in your bag.
Film your shot
Prop your phone side-on with your whole body in frame, or ask a friend. Upload a clip or use Live mode on court.
AI breaks it down
It finds every stroke in the clip, tracks 20+ body points through the swing and measures preparation, contact, footwork and more.
Get coached
See your score out of 100, the one thing to fix next and drills to fix it, then ask Coach Chris, your AI coach, anything.
A coach's eye on every stroke
The same breakdown a coach would give you, measured from your own video.
Every stroke scored out of 100
Upload a rally or a basket of balls. OnCourtAI finds each stroke, scores it and shows you the video alongside.

Padel Is Booming in the UK — Now How Do You Actually Get Better?
Britain's courts filled faster than its coaching did. We analyse nine padel strokes — bandeja and víbora included — not tennis shots relabelled.
The Courts Are Cold and Your Coach Is Booked. Now What?
Platform uploads peaked at 541 in July and fell to 303 by September. The off-season is when technique quietly decays — or when you quietly fix it.
What a Year of Data Says About Sticking With It
70% of players with 10+ sessions improved, against 52% below that, confirmed across 500 shuffles. Our earlier claim about spacing did not replicate.
