Before You Continue
Please review and accept the following to use SwingCheck AI.
Biometric Data Collection
We process the video you record or upload to extract biomechanics data — body pose keypoints, joint angles, and swing/throw timings. This is biometric data.
How Your Data Is Used
We use your data to generate your analysis and reports. We never sell it. Anonymized video excerpts may help improve our AI models only with your separate opt-in (faces blurred). Data is shared only with our processors (Stripe, Supabase) and any coach you choose to share with.
Coach Review
All coaches on the SwingCheck AI platform are reviewed before being granted access to player data.
AI Coach Is a Training Aid
The AI coach and analysis are training aids, not medical, coaching, or recruiting advice. We make no guarantee about accuracy or any recruiting outcome. Consult a licensed professional before making training or health decisions.
Parental Consent (Under 18)
SwingCheck AI is for athletes age 8 and up. For any player under 18, a parent or legal guardian must provide consent for the collection of their personal and biometric data, consistent with COPPA for children under 13.

Camera Setup Tips
Better setup = better analysis
📐
Side Angle (Best)
Set your phone perpendicular to the batter's box — directly to the side. This gives the clearest view of rotation, stride, and arm path.
📏
10-15 Feet Away
Far enough to see the full body from head to feet. Waist height or use a tripod for best results.
💡
Good Lighting
Face the light source if possible. Avoid backlighting (sun or lights behind the player).
🧍
Full Body Visible
Make sure head, hands, and feet are all in frame for the entire swing. No cropping!
⏱️
5-second countdown starts when you tap record. Max recording is 8 seconds — one good swing is all you need.

Upload Video

Upload cage footage, game at-bats, or slow-mo swings. Slow-mo (240fps) gives lab-quality results.
