Analyze a run

Upload a 5–15 second side-view clip with your full body in frame. No sign-up required — your video stays on your device.

How the analysis works

A pose model runs in your browser and tracks 17 body keypoints in every frame. From those, we compute cadence, trunk lean, knee flexion, vertical oscillation, arm symmetry, heel pickup, and — when direction of travel is clear — overstride.

Your video stays on your device — only the extracted metrics are computed in your browser.
