FAQ

Is it really free? Do I need an account?

Yes, free, and no account. Open the page and drop in a video.

Where does my video go?

Nowhere. Playback, drawing and AI detection all run inside your browser (only the AI model file is downloaded once).

How accurate are the AI pose lines?

It uses an open pose-estimation model (MediaPipe). Clothing, camera angle and blur can throw it off, so treat it as a guide and review the details with a coach.

Does it work for other sports?

Yes: tennis, pickleball, baseball swings, pitching, squats, anything where the whole body is in frame.

I am a coach. Can I send this to my students?

In the ProField app (free for coaches) you can send video analysis straight to your students and manage bookings and lesson passes in the same place. On this page, add your coach code (the invite code in My Page) under Share as link and the link shows your name and a booking button.
