For players who practice alone
Don't copy the pros. See the corrected you.
Film one swing. AI rebuilds it in 3D, finds the joints holding you back, and shows your own body hitting it right — from any angle.
Practicing alone? You record your swing… then what?
A score isn't a fix
Apps tell you what's wrong. They rarely show you what right looks like for you.
Pros don't have your body
Copying a pro's swing means copying a different height, reach and flexibility.
Lessons are great, but rare
Between lessons you're on your own, guessing whether the change you made is the right one.
How it works
-
Film one swing
Prop your phone at the side of the court and hit one serve. No sensors, no special setup.
-
AI rebuilds it in 3D
Your swing becomes a 3D model, and the one or two joints that matter most are flagged — like your elbow at contact.
-
Watch the corrected you
Same body, same swing — with just those joints fixed. Compare it with your original from any angle.
Not a score. Your own corrected swing.
A mirror between lessons — not a replacement for a good coach.
Who it's for
- Adult club players teaching themselves
- Roughly NTRP 2.5–3.5
- Anyone reviewing between lessons

Get early access when the iPhone app launches. After you sign up we'll ask four quick questions (optional) — they help us build the right thing.
FAQ
When does it launch?
We're building the iPhone app now. Waitlist members hear first and get early access before the public launch.
iPhone only? What about Android?
iPhone comes first. Tell us which phone you use after signing up — if enough Android players join, it moves up the list.
Where do my videos go?
Your videos are processed on secure cloud servers to build your 3D model and are never sold. You can delete them anytime.
How much will it cost?
Free to start, with an optional Premium plan planned at about $7.99–9.99 a month. See the pricing section above.
Which strokes are supported?
The serve first. Forehand, backhand and volley follow — tell us which one you want most.
Is my face or body data used to train AI?
No. Your videos are used only to create your analysis. Any use for research or training would be a separate, opt-in choice.
