Level up your game with an Ally on and off the court.
An AI coach that talks with you — typed or in a live voice conversation — analyzes film of your swing, and drives a plan built around your goals. It remembers every session, so each one starts where the last left off.
You I keep losing to the same lefty. His serve drags me off the court every single time.
Coach That wide slice to your ad side — it held you until four-all last time, then you started guiding it. Stand one step further over and take it early, chest high. Want me to build the plan for Saturday?
You Yeah, let's do it.
Coach Done. Tuesday we groove that return. Thursday, first-strike patterns. I'll check in after each one.
First open. One idea, one action: meet your coach.
Tennis AllyA coach who
knows your game.
Talk about your tennis and get a real answer. Your coach remembers every conversation and builds on it.
Home is the conversation. The coach speaks first when it has a reason — here, Saturday’s rematch. Voice is the big yellow ball.
The coach’s model of you, visible and correctable. This is what makes month six worth more than week one.
Your game
Your coach’s read on your game. Tap anything that’s wrong — corrections stick.
Three straight third-set losses since Aug 12. Your first sets are your best tennis.
When your coach says “show me.”
Your coach asks to see something when talking isn’t enough — a specific stroke, filmed a specific way, for a reason it explains.
Which stroke, how to film it, and why — side-on from the fence, one or two swings is plenty.
Can’t get to a court until Thursday? Your coach holds the thread and picks it up Thursday.
At most two corrections, ranked so you know what to work on first, and one drill.
The finding joins your coach’s model of you — and gets followed up next week.
And the door swings both ways: film a stroke any time and ask your coach what’s wrong with it.
Your video stays on your phone — your coach reads a handful of still frames, never the footage itself.
0:11A coach in your pocket.
Conversation is how it works — everything else is something your coach reaches for.
Talk it through
Bring a loss, a rematch, or two free hours on Wednesday — typed or out loud in a live voice session — and get questions, opinions, and a plan sized to you.
Your coach watches film
Film a swing when it matters and get back the highest-leverage fix and one drill. The video stays on your phone.
Keeps you moving toward your goals
Practice plans built around your week, a game plan the night before a match, and follow-ups on what you committed to — on and off the court, the way a personal coach would.
The early returns are in.
“I’m on court with forty students a week, and I can’t be there the other six days. Tennis Ally coaches the way I coach — it asks first, then it fixes one thing at a time. My students who use it show up already knowing what we’re working on.”Rosa Alvarez · Teaching pro & two-time NorCal sectional champion
“My coach messaged me first”
The night before my rematch it checked in with a plan for the lefty’s serve. I won in straight sets.
“Corrections actually stick”
It remembered my toss drift from two weeks ago and asked how the fence drill went. Month two beats month one.
“My third sets stopped collapsing”
It spotted that I lose third sets before I noticed. We built a tight-game routine and I’ve won two of my last three.
Your first session is a conversation.
Your coach opens with a question about your game and starts building its picture of you. Every session after adds to it.
