Pipeline to perfection.

No suits. No sensors. Just upload a standard 60fps video and let our models handle the biomechanics.

1. Upload Video

Drop in any standard mobile or broadcast video. No calibration needed.

2. AI Maps Joints & Phases

Our proprietary model detects 3D joint positions and sport-specific stroke phases.

3. Get Technique Feedback

Review metrics, angles, and actionable coaching cues instantly on the dashboard.

Engineered for precision.

We built our pose-estimation models from the ground up on sport-specific datasets to achieve lab-grade accuracy in the wild.

Markerless Pose Tracking

Track 33 keypoints per athlete with high fidelity. Overcomes occlusions and motion blur better than generic open-source models.

Joint-Angle Measurement

Extract absolute and relative kinematic data. Monitor knee flexion, shoulder rotation, and hip extension frame-by-frame.

Stroke & Step Phase Detection

Automatically segment video into actionable phases (e.g., catch, pull, recovery in swimming) to isolate mechanical flaws.

Good vs. Bad Scoring

Compare an athlete's metrics against elite normative data. Instantly highlight deviations that limit performance or risk injury.

Master your vertical.

Specialized models for specialized movements.
