Think of me as an LLM built around one thing:
making you a better tennis player.

I run this whole app. Tell me what you want — I open the camera, pull up the right drill, build your match plan. You never hunt for a menu. You talk, I act.
Record•Analyze•Correct•Train•Improve

Film from the side so your stroke and the ball are both visible. Trim your stroke and tap analyze.

All your recordings in one place. Tap the green folder to upload videos from your phone gallery.

109 biomechanical metrics processed: torso rotation, knee flexion, contact phases.

See your skeleton tracked frame by frame. Phase-by-phase breakdown of every shot.

Get your score out of 100, phase breakdown, and a list of exactly what to fix.

Axel picks your top drill based on your weakest metrics. Targeted improvement.

Full library by stroke and level. Serve, forehand, backhand — beginner to intermediate.

Each drill has a video demo by a certified coach. Practice exactly the right way.

Live corrections on the court. Auto-detect strokes and fix errors in real time.
Coach, video analyst, opponent scout, the one who remembers what you worked on last month — I am all of it. And I answer at eleven at night, the day before your match.
Here is everything I do. Reading your stroke is one of them.
Tactics, technique, the mental side, fitness, nutrition — and who plays whom on tour this week. No form to fill, no menu to find. You ask, I answer, and I pick up where we left off last time.
Tell me who you play and on what surface. I build the game plan — two or three things to actually do out there, based on how you play, not on generic advice.
Say it and it happens: I open the camera, pull up the right drill, show you your last analysis, switch the language. You never hunt for a menu — I know every screen in here.
Phone against the fence, racket in hand — I listen and I talk back, so you never look at the screen. In English, French, Spanish, Italian, German, Portuguese, Turkish, Arabic, Hindi or Chinese. The whole app follows.
Serve, forehand, backhand. 109 measurements across the six moments of a stroke, compared to the range the best players live in. Score out of 100, skeleton overlay, side-by-side with a pro.
Live session on court: I follow your body in real time and tell you what to change between two balls, not two days later.
Not a library to browse. I choose the exercise that fixes the fault I just saw, walk you through it step by step, count the sets with you, and remind you when it’s time to do it again.
Your level, your recurring faults, what we fixed last month, your scores over time. And when I get something wrong, tell me — I keep the correction and I don’t repeat it.
I do not replace them. A coach scans their student in, sees every analysis, builds the plan and runs live sessions — and I stay with the player the six days a week they cannot.
We're not changing how players train. We're changing how they think about their game.
