Upload a clip from any phone. Rowing, running and golf are graded against a sport rubric, anything else against a reference — with a coach that names the stroke and the frame behind every claim. No markers, no studio, nothing to install.

A live session, in this page

Six panels, one real erg piece — running right here.

Not screenshots. Below is the dashboard's own analysis of a real 20-second clip — the same sample the product's guest demo uses — with its grader maths ported to run in your browser. Play the video, scrub a stroke, click a metric, ask the coach.

The verdict

One thing to work on, ranked by points.

The metric worth the most points comes first — your value against the target band, a cue, and the stroke to watch. Six qualities of the session sit beside it, and Technique and Performance are graded separately.

What to work on
● Your one thing

Layback

worth 3.7 pts
You: 40°Target: 9.2–37.2°

A controlled layback finishes the stroke using the trunk's power.

Cue
Aim for ~20-26° of layback — body tall but leaning back, not collapsed.

Speed & sequence

Legs, back, arms — in that order?

When each body segment hits peak speed across the selected stroke, drive and recovery separated. Click the chart and the video jumps there.

3D reconstruction

Rotate the stroke.

The same landmarks, lifted with the model's own depth estimate. Drag to rotate; it follows the video.

Position across the image is measured from the video. Depth comes from the pose model's own per-joint estimate, not from a second camera — treat sagittal angles as measured and depth as inferred. The dashboard's 3D Lab adds a second phone for true triangulation.

AI coach

A coach that reads the session before it speaks.

Press generate and watch it query the strokes and history first, then write — citing the stroke and frame behind every claim. This is a recorded run against this clip; on your own session it runs live.
