In 2025, the best tennis players aren’t just relying on human coaches – they’re using an AI tennis coach that never sleeps, never misses a detail, and gives instant feedback on every single stroke.
Welcome to OnCourtAI – your personal AI tennis coach that analyses over 30,000 data points from a typical 30-second video, breaking down more than 40 different phases of every stroke: serves, forehands, backhands and volleys.
No more waiting days for your coach’s notes. No more guessing what went wrong. Just pure, data-driven insights the moment you finish filming.
Why an AI Tennis Coach is the Future of Improvement
Traditional coaching is fantastic – but it’s limited. A human coach can watch your stroke and give great advice, but they can’t track 30,000 measurements in real time. The human brain cant process this amount of data in real time. And they can’t be with you every single practice session.
OnCourtAI changes all that. Our AI tennis coach is available 24/7, analysing every detail of your game with precision that surpasses even the best human eye.
Players using OnCourtAI improve 2.8× faster than those relying on traditional coaching alone – because feedback is instant, specific, and repeatable.
Instant In-Depth Analysis for Every Major Stroke
Serves: Unlock Hidden Power & Consistency
Your serve is the only stroke you fully control – yet most players leave massive potential on the table. OnCourtAI analyses 8 phases including:
- Toss placement and height consistency
- Knee bend depth and timing (130–150° optimal)
- Trophy position accuracy
- Racket drop depth and speed
- Contact point reach (90–98% of maximum)
- Pronation timing and spin rate (RPM)
Result? Players see average serve speed increases of 12–18 mph and placement accuracy improvements of 34% within 8 weeks.
Forehands: Build a Reliable Weapon
The forehand is often your biggest point-winner. Our AI tennis coach breaks down 8 phases including preparation, X-factor separation, low-to-high swing path, contact zone, and topspin generation.
Common discoveries:
- Insufficient shoulder-hip separation (average amateur: 22° vs pro: 45–60°)
- Contact too low (below hip height in 68% of shots)
- Inconsistent swing path causing floating balls
Players fixing these issues gain 28% more depth control and 41% more winners.
Backhands: Turn Your Weakness into Strength
Whether one-handed or two-handed, backhands get the same data point treatment across 8 phases – preparation, contact point, follow through, slice depth, and recovery speed.
Our AI tennis coach helps players transform unreliable backhands into consistent weapons, with users reporting 37% more backhand winners after targeted training.
Volleys: Dominate the Net with Precision
Volleys require split-second decisions. OnCourtAI analyses split-step timing, punch depth, hand position, and reaction time – helping net players win 31% more points at the net.
