Pose analysis · in-browser · MediaPipe
Biomechanics,
measured.
Body landmarks become joint angles, and joint angles become a score you can audit check by check. Your photo never leaves your device.

How a score is computed
Deterministic and explainable: the same photo always gets the same score. If the camera view, framing or landmark coverage isn't good enough, the gate returns a prompt instead of a number.

Generated from the scoring code. Full credit inside the tolerance, partial credit up to twice the tolerance, zero beyond.
