Hey. I'm Axel. The GPT of tennis.

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

The App in Action

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.

App Features

Here is everything I do. Reading your stroke is one of them.

Ask me anything

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.

Tomorrow’s match

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.

I run the app

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.

Out loud, in your language

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.

I read your stroke

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.

I correct you while you hit

Live session on court: I follow your body in real time and tell you what to change between two balls, not two days later.

The drill for your fault

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.

I remember you

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 work with your coach

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.

Business Overview

We're not changing how players train. We're changing how they think about their game.

The Problem

  • A coach costs $50 to $150 an hour. Almost nobody can afford that every week
  • Even when you can, the good ones have waiting lists
  • Millions of players live nowhere near a qualified coach at all
  • And between two lessons, there is no one to ask. That is where the questions actually come up

What I do about it

  • I answer, all day, every day, for the price of one lesson a year — technique, tactics, the mental side, the match plan
  • I read serve, forehand and backhand on video, and I correct you live while you are still on court
  • I pick the drill for the fault I measured, and I walk you through it — I never hand you a list
  • I remember everything: your level, your recurring faults, what we already fixed. In ten languages

Who I am for

  • Competitive players (40%) — school, college and club. They already train hard; what they lack is someone to tell them what to work on
  • Coaches (30%) — I do not replace them. I measure, I keep the record, and I stay with their players the six days a week they cannot
  • Everyone else (30%) — the Saturday players who never had a coach at all, and never will at $100 an hour

How it pays for itself

  • Freemium SaaS — seven days free, everything open. Then Pro at $6.99/month or $69.99/year: talk to me without limit, 20 video analyses, unlimited sessions on court. $3.99 for members of a partner club
  • B2B — clubs, academies and federations licence me for their whole roster; the coach keeps the eye, I keep the record
  • Market — $3.2B spent on tennis coaching worldwide every year, growing 6.5% a year
