The workflow
From one clip to a coached breakdown.
A serve is a sequence — toss, trophy, contact, follow-through. SwingAI reads it the same way, in order, frame by frame. (Serve now; forehand and backhand coming soon.)
Record or upload
Record a serve right inside the app, or upload a clip straight from your camera roll. No sensors, no markers — any modern phone works.

Questions
Good to know before you serve.
Just your phone. Prop it on the fence or a bag at roughly net height, film a rally or serve from the side, and upload the clip. No sensors, wearables, or special cameras required.
Right now SwingAI analyzes your serve. Forehand and backhand are coming next — each scored on its own model, so the feedback is specific to that shot.
SwingAI tracks 30 body and racket keypoints per frame at up to 120fps to reconstruct your motion in 3D. It's built to surface the same things a good coach would spot on video — contact point, racket path, rotation, and timing.
Your clips are yours. They're processed to generate your analysis and never sold or shared. You can delete any video, and its data, from your account at any time.
No. SwingAI is built to stand on its own — scores, frame-by-frame breakdowns, and drills in plain language. If you do have a coach, it's a great way to track progress between sessions.
