StrokeScore AI
On-device AI

AI rowing biomechanics

See the stroke. Understand the movement.

Upload an on-water clip to measure rowing rhythm, joint angles, and drive sequencing—without markers or wearables.

Stroke profile

The measurements you’ll receive

Sample values

Catch knee angle

54°Lower value = more compression

Finish knee angle

164°Extension at the end of the leg drive

Trunk swing range

31°Change in torso angle through the cycle

Stroke consistency

91%Similarity of repeating movement patterns

Strong drive sequencing

The leg-to-trunk timing stayed repeatable across the analyzed strokes. Preserve that order as the rate rises.

Balanced drive-to-recovery rhythm

The shell has time to run between strokes without making the drive feel slow.

Sculling-specific next check

A stern view would complement this analysis by checking hand heights and left-right blade symmetry.

Built for real rowing footage

From video to useful feedback

StrokeScore AI runs a pose-landmark model in your browser, tracks the most visible side of the athlete, calculates two-dimensional joint angles, and segments the stroke from repeating knee motion.

  1. 01
    Record

    Film from shore, side-on, with the full athlete and shell visible.

  2. 02
    Track

    The on-device model estimates 33 body landmarks frame by frame.

  3. 03
    Interpret

    Rowing-specific heuristics turn angles and timing into transparent coaching cues.

Privacy first. Analysis happens locally in your browser; this prototype does not upload or store your video. Results are 2D estimates for coaching and exploration, not medical assessment.
