The problem
You think you know what's wrong with your swing
What you feel and what is actually happening in your swing are rarely the same thing. Most golfers have a theory — and most theories are wrong.
Feel ≠ Real
The disconnect between felt movement and actual movement is the most significant barrier to lasting improvement
Every lesson
Without objective data is based on subjective observation — not what the physics and biomechanics are producing
The data
Biomechanics and physics swing data you need exists inside your swing. It just hasn't been visible — until now
Video capture
Works with face-on video for full joint-pair tracking. Set golfer gender, handedness, player level and club type for calibrated analysis
What it does
Analysis your eye cannot perform
SwingTrace processes your swing at the frame level against physics-derived biomechanical baselines — supports coaching intuition, not generic templates.
Know exactly where your power leaks — and why
AI kinematic sequencing maps your arms, torso, and hip & leg dynamics against a physics-based benchmark. See immediately where your sequence breaks down and in which direction.
Built on the biomechanical framework from The Physics & Biomechanics of Golf by Barrie Van Proctor.
Instant results. No cloud wait. No privacy compromise.
All analysis runs locally in your browser — your swing video is never uploaded to a server. Results are immediate and completely private.
Works on any modern browser — desktop, laptop, tablet, or phone. No installation required.
Track the one thing that matters most
After each analysis, commit to one biomechanical metric as your practice focus. SwingTrace tracks it across every subsequent swing and displays a sparkline trend chart — so you can see objectively whether the work is paying off.
Practice: 1 focus goal · Perform: 3 goals · Coach: 3 goals per student
Your improvement story, at a glance
Subscribers land on the Progress Dashboard — a home screen showing swing history by date, active focus goals, and trend sparklines. Your progress laid out in one view, every time you sign in.
AI coaching commentary after every swing
AI-powered coaching commentary generated after every analysis. Includes a Your Focus priority — the lowest-starred trainable metric surfaced with a 35-word actionable instruction. Clarity, not noise.
No manual scrubbing. Positions detected automatically.
SwingTrace uses computer vision and in-browser AI pose-detection to automatically detect your P2–P7 swing phase markers. The app places the positions for you — no timeline scrubbing required, just a quick check and confirm.
A rank that reflects your commitment
Your dedication to improvement is recognised in the app. Progress through six ranks — Casual, Player, Committed, Power User, Expert, and Elite — visible in your Account tab.
Subscriber features require a Practice, Perform, or Coach plan.
The process
From video to insight in a few minutes
-
Record or upload your swing
Use your phone's slow-motion camera at 60, 120, or 240fps. Set up face-on or down the line — record yourself, or have a friend film you. Drag the clip into SwingTrace.
-
AI maps your kinematic sequence
SwingTrace automatically detects your P2–P7 swing positions using pose estimation, then processes every frame: tracking hip rotation, shoulder coil, arm path, and club trajectory against biomechanical baselines. In your browser.
-
Understand what's happening — and track it over time
Review your swing frame by frame with position overlays. See precisely where your sequence diverges from optimal. Subscribers track progress across sessions with Focus Tracking and the Progress Dashboard.

What golfers say
Real results from real swings
"This has really helped enhance my biomechanics background. It also allows a speedy improvement plan to be built around what the numbers show."
"Used SwingTrace AI to assess a number of my players. The detailed data identified effieciency gains and helped drive-up club speed."

Questions
Common questions
SwingTrace AI Pro is free to trial — open it in your browser and start
analysing immediately. No download, no app install, and no subscription required to start.
SwingTrace is useful at all ability levels. The biomechanical analysis is
objective — it doesn't require a low handicap to be meaningful. Beginners benefit from understanding the
fundamentals; coaches and competition players use it to refine all aspects of biomechanics, force
production and sequencing.
No. All analysis runs locally in your browser. Your swing video is never
uploaded to a server — data stays completely private and results are delivered straight to your device.
SwingTrace works best with video at 60, 120, or 240fps — higher framerates
increase overall accuracy, particularly when comparing across sessions. We also provide free slow-motion
conversion which makes video fidelity even higher on modern smartphones.
SwingTrace AI Pro was conceptualised and created by the author of The
Physics & Biomechanics of Golf. The analysis framework is built on the same biomechanical
principles documented in the book. Learn more at golfbiomechanics.net.
Nothing. The free tier gives you unlimited analyses, but no swing history
is saved and Focus Tracking is not available. Subscribe to unlock saved history, Focus Tracking, the
Progress Dashboard, and AI coaching summaries.
A subscription unlocks saved swing history, Focus Tracking — commit to a
biomechanical focus goal and track it across sessions with a sparkline trend chart — the Progress
Dashboard, and AI-powered coaching commentary after every analysis.
The Coach tier includes everything in Perform, plus student management.
Add students, run analyses on their behalf, and track each student's progress separately. Per student:
up to 3 Focus goals charted and tracked and up to 30 saved swings. When the cap is reached, the oldest swing is removed
automatically.
Monthly subscription credits do not roll over — unused credits expire at
the end of each billing period. Top-up credits purchased separately never expire.
