X-Factor analysis
Shoulder–hip separation at the top, measured in 3D from a down-the-line video — shown only when the camera angle makes it reliable.
Upload one swing video. We track your body and the club head frame by frame, measure tempo, rotation and hip sway — then an AI coach tells you exactly what to fix.
Down-the-line or face-on, any phone video. mp4 or mov up to 100 MB, one swing under 15 seconds.
Pose and club-head models follow you frame by frame and find address, top, impact and finish automatically.
An AI coach reads your tempo, rotation, head stability, hip sway and even the numbers on your simulator screen — and tells you what to fix next.
Shoulder–hip separation at the top, measured in 3D from a down-the-line video — shown only when the camera angle makes it reliable.
Backswing-to-downswing timing. Tour pros average 3:1 — we measure yours to two decimals.
The club head is tracked frame by frame and drawn as a slow-motion replay: backswing in blue, downswing in red.
No jargon dump. You get 2-3 things you did well, 2-3 to fix, and what to practice next.
Filming in a simulator bay? We read ball speed, club speed, carry and spin straight off the screen and build them into your report. Keep recording about 5 seconds after impact so the screen has time to show that shot.
Your video is used only to produce your report. Replay videos are deleted automatically within 24 hours, and we never share or sell them.
Best results: phone on a tripod, whole body and club in frame, good light, 60 fps if you can.

If you agree, we keep this swing to improve our analysis models. Nothing is kept unless you choose to, and you can withdraw anytime.
Skeleton data & numbers: the analysis summary, per-frame body keypoints, club-head positions and any launch-monitor numbers read from the screen — no video. Video: the above plus the video, with your face blurred and the audio silenced except half a second around impact; videos with other people in frame are not kept. Stored on our own server in Canada, used only to improve GolfTrace, never sold or shared, no face recognition, kept for up to 3 years. Withdrawing deletes it immediately; model versions already trained can't un-learn a single swing, but it won't be used again.

GolfTrace partners with these coaches. Recommendations are based on this report and each coach's specialties; contact details are provided by the coaches themselves, and GolfTrace never passes on your personal information.
Every swing you analyze is saved on this device only (not on our server). Film from the same spot each time — numbers from different camera positions aren't comparable.
Yes — the video is uploaded to our server so it can be analyzed there. The original upload is deleted as soon as the analysis finishes, the replay videos and key frames we generate are deleted automatically within 24 hours, and the text report is kept for 30 days. Only the numeric metrics (angles, timings) are sent to Anthropic's Claude to write the coaching text; if your video shows a launch-monitor screen we can't read locally, a small crop of that screen may be sent to Claude to read the numbers.
The sample swing is free. Analyzing your own swing is a one-off payment per video — the price is shown on the analyze button. If the analysis fails, you are not charged.
Down-the-line (behind your hands, looking at the target) gives rotation and swing plane; face-on gives hip sway and impact. Use a tripod or a steady surface, keep your whole body and the club in frame, film in good light at 60 fps if your phone allows, and trim the clip to one swing (3–10 seconds). Hitting into a simulator? Keep about 5 seconds after impact — the screen only updates once the ball has landed.
The prototype is tuned for full swings. Short-game motion uses a different scoring model and is on the roadmap.
The angle difference between your shoulder line and hip line at the top of the backswing. Bigger separation = more stored power. Amateurs average around 30°; tour pros 40–50°.
Some measurements can only be trusted from certain camera angles. Rotation (X-Factor, shoulder and hip turn) needs a down-the-line view; hip sway needs a face-on view. When the angle is not right we show N/A instead of a wrong number.
