Free AI Golf Swing Analyzer

Yes — completely free, with no signup, email collection, watermarked exports behind a paywall, or trial period. The tool runs entirely in your browser using advanced AI body-tracking technology. There’s no premium tier and nothing locked behind a subscription. We’re currently in public beta and improving it every week.

Yes. The tool works on any modern smartphone or computer browser — iPhone Safari, Android Chrome, desktop Chrome, Edge, Firefox, and Safari on Mac. No app to download. Just open the page and upload.

Your video never leaves your device. All AI processing happens locally inside your browser using your phone or computer’s own processing power. We don’t see it, store it, or upload it anywhere. When you close the tab, the video is gone.

33 body landmarks across every frame — shoulders, elbows, wrists, hands, hips, knees, ankles, feet, head, and face. Connecting lines visualize your full kinetic chain.

From that tracking, we compute swing metrics with Tour benchmarks: tempo ratio (backswing : downswing), head movement (lateral and vertical), hip rotation at impact, knee flex retention, backswing length, and swing speed estimates. Each metric tells you the value, the Tour standard, and what your number suggests.

When conditions aren’t right for a measurement (e.g. low frame rate for speed), we lock the metric instead of guessing — and tell you exactly how to unlock it.

Body tracking is our current priority and we’re sharpening it every release — pose stabilization, foot anchoring, swing speed calibration against real launch monitor data.

Club tracking is on our roadmap. Reliable shaft and clubface tracking at consumer phone frame rates (where the clubhead moves over 100 mph and motion blur is heavy) is a hard, mostly unsolved problem — that’s where multi-camera and launch monitor systems earn their cost. But we’re actively exploring approaches and will share progress as it happens. Stay tuned.

Two angles work best:

Face-on: Camera placed directly in front of you, perpendicular to your target line, at chest height. Best for seeing tempo, weight shift, head movement, and arm positions. Required for swing speed measurement.

Down-the-line: Camera placed behind you on your target line, at hand height, lens centered on your hands at address. Best for seeing swing plane, posture, and shaft angle.

Make sure your full body is in the frame, including the top of your backswing and your feet. Good lighting helps a lot.

Yes — 30 seconds maximum. Most users land at 5-15 seconds, which analyzes faster and gives the cleanest peak detection. If your clip is longer, trim it in your phone’s Photos app first (iPhone Photos and Google Photos both have built-in trimmers).

Yes — after analysis completes, you’ll see a Save to my Phone button on mobile (or Download to my Computer on desktop) that records a ~20 second clip with all the AI overlays baked in: skeleton lines, swing metrics HUD, and Golf Swing Lens branding.

On mobile, the share sheet opens with options to save to your camera roll or send straight to Instagram, TikTok, etc. On desktop, it downloads to your computer. Tag @golfsimulatorvideos if you post it!

Yes. Toggle Launch Monitor Mode below the club picker before uploading. After the quality check, you’ll be prompted for ball speed, launch angle, spin rate, carry distance, and smash factor — all optional, fill in whatever your launch monitor gave you.

Works with any launch monitor: Garmin R10, R50, Mevo, Mevo+, SkyTrak, Foresight GCQuad, GC3, Trackman, Rapsodo MLM2Pro, Square Golf, Uneekor, ProTee, or any other. The outcome metrics show alongside your body tracking so you can see cause and effect.

Most paid analyzers show confident-looking numbers regardless of whether your video was good enough to measure them. We don’t. When the frame rate or camera angle isn’t right for a measurement, we lock the metric and tell you exactly how to fix it — instead of feeding you a fabricated number.

We’re also actively calibrating swing speed against real launch monitor data (Foresight GCQuad ground-truth) to publish verified accuracy claims, and we let you pair the analyzer with your own launch monitor for outcome data alongside body metrics. That combination — honest body tracking + your launch monitor data + transparent calibration — isn’t something the paid apps offer.

No. This is just a video analysis tool — record any swing, anywhere. You’ll get tempo, head movement, hip rotation, swing speed estimates, and the rest of the body metrics from a phone video alone.

That said, if you have a launch monitor, toggling Launch Monitor Mode on adds the outcome side of the picture — ball speed, launch angle, spin rate, smash factor — for full cause-and-effect coaching. We’ve personally tested most launch monitors on the Golf Simulator Videos YouTube channel and offer free planning help if you’re shopping for one.
