Description
TENNIS AI 2.0 – AXEL : YOUR AI COACH, ANYTIME, ANYWHERE.
Film your shot. Get your diagnosis. Improve immediately.
Tennis AI is the first app to deliver real-time biomechanical analysis of your tennis technique — directly from your smartphone, no equipment needed.
HOW IT WORKS
Step 1 — Set up in seconds
Open the app, select Auto-Detect or choose your stroke manually. Position your phone at the sideline — Axel, your AI coach, guides you through the exact camera placement for optimal analysis. No tripod required, though one is recommended for best results.
Step 2 — Play your shot naturally
Just play tennis. Tennis AI uses your smartphone camera combined with on-device computer vision (MediaPipe) to track 33 points of your body in real time at 30 frames per second. No wearables, no sensors, no special equipment.
Step 3 — AI detects your stroke automatically
The system recognizes whether you are hitting a serve, forehand, or backhand — automatically, without you pressing anything. It identifies the six key biomechanical moments of your swing: preparation, backswing, trophy position, contact point, follow-through, and finish.
Step 4 — Receive your full technical diagnosis
Within seconds of finishing your shot, you get a complete breakdown: your score out of 100, your measured values across 107 biomechanical metrics, a comparison against professional player ranges, and a prioritized list of errors to fix.
Step 5 — Fix errors in real time with Axel
Tap any error and enter Live Correction mode ou go directly to the drills to fix it. Axel watches you play, tells you exactly what to adjust, and confirms when you have fixed it — correction by correction, metric by metric.
Step 6 — Track your progress over time
Every analysis is saved. Review your past sessions, track improvements across metrics, and see how your technique evolves over weeks and months of practice.
WHO IT'S FOR
• Recreational players who want to improve faster
• Competitive players optimizing their technique
• Coaches and academies integrating AI into their teaching
• Tennis clubs looking for scalable player development tools
TECHNOLOGY
Tennis AI combines computer vision (MediaPipe, YOLO), generative AI, and the expertise of certified professional coaches to deliver analysis previously available only in elite training centers.

WHAT'S NEW IN VERSION 2.0
REAL-TIME ANALYSIS
Tennis AI 2.0 introduces the most significant upgrade in the app's history: full biomechanical analysis delivered in real time, the moment you finish your swing. No uploading, no waiting, no delay. Your technique is analyzed frame by frame as you play, and your results appear within seconds of your last shot.
Real-Time Coach Mode
Tennis AI's Real-Time Coaching Mode turns your smartphone into a personal biomechanics coach. Point your camera at the court, select your stroke — serve, forehand, or backhand — and Axel, your AI coach, starts watching.
After your first shot, Axel identifies your technical errors and focuses on the most important one. You get 3 attempts to correct it. Axel tracks your progress rep by rep, gives you instant feedback, and tells you if you've improved. Once done, you move to the next error — or retry if you need more work.
No uploads, no waiting. Everything is analyzed on-device in real time, just like having a coach on the court with you.
107 BIOMECHANICAL METRICS
Every stroke is evaluated across 107 distinct biomechanical metrics — covering stance width, knee flexion, trunk tilt, shoulder alignment, elbow position, wrist angle, racket path, contact point height, follow-through extension, and dozens more. Each metric is measured against professional player ranges.
KEY MOMENT DETECTION
The AI automatically identifies the six critical phases of every stroke: preparation, backswing, trophy position, contact, follow-through, and finish. Each phase is analyzed independently, so you get granular feedback on what went wrong, at exactly which point in your swing.
AXEL, YOUR AI COACH
Axel is a conversational AI coach who speaks to you live during your session. He announces what he sees, tells you what to fix, encourages you when you get it right, and adapts his coaching to your specific errors — correction by correction, in natural spoken language.
LIVE CORRECTION MODE
Once your analysis is complete, enter Live Correction mode from any error. Axel loads your specific errors, focuses on the one you chose, watches you play, and confirms the fix in real time. You do not move to the next error until the current one is corrected.
AUTO-DETECT STROKE RECOGNITION
The AI watches your movement and identifies whether you are hitting a serve, forehand, or backhand — without you pressing anything. Detection uses a rolling biomechanical analysis of wrist position, elbow height, body rotation, and movement patterns.
CERTIFIED CORRECTIVE DRILLS
Every error comes with a corrective drill designed with certified professional tennis coaches. Each drill includes step-by-step instructions, video guidance, and real-time AI feedback so you can measure whether the drill is actually fixing the underlying issue.
