Cole, the AI
tennis coach.

Upload a swing and Cole finds the one thing to fix, and why. Or just ask it anything, tactics, drills, movement, the mental game. One coach for your whole game.

How it works

Three steps, one thing to practice.

01

Film your stroke

Forehand or backhand. A phone resting on the fence is enough. A few reps from the side of the court gives Cole the most to work with.

02

Get your one focus

The coach reads every phase of your swing and picks the single change that matters most for you right now, with a cue you can hold in your head.

03

Recheck when ready

Film again after you have worked on it. The coach tells you whether it is fixed, and what to move on to next.

What it sees

It reads the whole swing, the way a coach does.

On forehand and backhand, Cole follows the swing from the first turn to the finish, and how each part sets up the next.

Cole doesn't run down a checklist. It takes in the whole motion, from the first turn of your body to the finish, and reads how each part sets up the next, the way an experienced coach's eye reads a swing at a glance.

That is what lets it find the one change that actually matters right now, instead of handing you a list of fixes.

One focus, one cue.

Most swing tips overwhelm you with a dozen fixes at once. Cole weighs the whole swing, then hands back the single change with the most leverage, and one short cue to remember while you hit.

What a cue looks like
"Finish your preparation before the ball bounces."
What you can ask

One coach for the whole game.

Drop in a swing for analysis, or just ask. Cole handles the parts of the game a good coach would, all in one conversation.
