Generic video tools look at "a person moving." We built a model specifically around sprints. the phases, the mechanics, and the coaching language real sprints coaches use.
Upload the rep. We extract the critical frames. You get a breakdown in plain English with priority tags. critical, worth working on, fine.
These are the technique patterns we see over and over again across sprints athletes. Each one has a specific look on video and a specific fix.
You reach full upright posture in the first 5-7 meters instead of staying angled forward through 15-20m.
Drive-phase wall pushes and resisted sled starts to groove a lower angle for longer.
Your front foot is landing ahead of your center of mass in steps 2-4, creating a braking force every step.
Short, punchy first-step drills with a focus on foot contact behind the hips.
Your hands swing past the center line instead of front-to-back, leaking rotational energy.
Arm-swing mirror drills and 'paint the line' focus cues at jog pace.
From freshman sprints to D1 rosters, athletes upload phone video and get the same frame-by-frame coaching read. The AI doesn't grade you. it explains what it sees, in the vocabulary a real sprints coach would use.
