Your AI tennis coach reviews the actual footage frame by frame — then scores your technique and tells you exactly what to practice next.
A frontier vision model watches the frames of your clip — the way a coach watches your swing — and gives you honest, specific feedback.
Film your serve, forehand, backhand, volley, footwork, rally, return, or match play. Your coach reviews the real footage, up to 30 seconds.
An overall practice score plus technique, consistency, footwork, and focus sub-scores — calibrated to your level, not a generic scale.
What's working, the one thing to fix first, and a cue to take into your next session — written around what actually happened in your clip.
Every report points you to specific drills from a curated library — each with instructions, a success metric, and a coaching cue.
Count rallies live, track your longest and average, and build a journal of every practice, filterable by stroke.
If a clip doesn't clearly show your stroke, it says so instead of inventing feedback. You can trust what it tells you.
Record or import a short, side-on clip of the stroke you're working on — up to 30 seconds.
It reviews the footage frame by frame. Keep training — close the app and we'll notify you the moment your report is ready.
Open your report: scores, a coach's note, what looks good, and the exact drills to run next.
No account. No sign-up. Your videos stay on your device — only still frames are sent, securely and only when you request an analysis, and they're never stored. Everything else works entirely on your phone.
Film one stroke today and see what your AI coach notices.
