AI Golf Swing Coach: Find and Fix the Faults Holding You Back

Every golfer has swing faults. The difference between golfers who improve and golfers who stay stuck is knowing exactly which fault to work on and having a plan to fix it. An AI golf swing coach gives you that clarity on every single practice session.

GolfCoach breaks your swing down into five key phases — address, backswing, top, impact, and finish — and evaluates four critical mechanics. In under 3 seconds, you know exactly what is going wrong, why it matters, and what to do about it.

Stop guessing what is wrong with your swing. GolfCoach identifies your specific fault and gives you one clear thing to fix, every session.

The 4 Swing Metrics GolfCoach Evaluates

Swing Plane

Is your club path inside, neutral, or over the top? The AI tracks the club's arc relative to your body. An inside or outside path is the root cause of most slices and hooks.

Hip Rotation

Power comes from the ground up. The AI measures your hip turn at address, the top of your backswing, and impact. Limited rotation leads to arms-only swings and lost distance.

Head Stability

Excessive lateral or vertical head movement during the swing causes inconsistent contact. The AI tracks displacement frame by frame and flags when movement exceeds the threshold.

Tempo

Your backswing-to-downswing ratio reveals whether you are rushing the transition. Tour average is 3:1. The AI calculates your exact ratio and identifies if a rushed tempo is costing you accuracy.

Common Swing Faults the AI Detects

Here are the most common issues GolfCoach identifies in amateur swings:

Over the Top

The most common fault in golf. Your downswing starts with the shoulders instead of the hips, throwing the club outside the target line. This produces pulls and slices. GolfCoach detects it through swing plane analysis and recommends drills that train the proper downswing sequence.

Early Extension

Your hips thrust toward the ball during the downswing instead of rotating. This forces your hands to compensate, leading to blocks and hooks. GolfCoach flags this through hip rotation measurement and tracks whether your extension is improving.

Rushed Tempo

Snatching the club from the top of the backswing destroys timing and consistency. GolfCoach measures your tempo ratio and provides drills focused on rhythm and transition. Most amateurs improve their ball striking significantly just by slowing down the transition.

Swaying Off the Ball

Lateral head movement during the backswing shifts your low point and makes consistent contact nearly impossible. GolfCoach tracks head displacement in centimeters and alerts you when it exceeds an acceptable range.

How the Swing Analysis Works

  1. Record — 5-second video from down-the-line or face-on. Place your phone at hand height, 8-10 feet away.
  2. Mark 5 positions — Address, top of backswing, impact, follow-through, finish. The app guides you through each one. You can undo and redo any position.
  3. AI analyzes — Pose detection identifies your joint positions. Claude Vision AI evaluates all 4 metrics. Skeleton overlay shows your positions visually.
  4. Get your coaching tip — A clear explanation of your primary fault, why it happens, and a specific drill to fix it.
  5. Track over time — Trend charts show whether your fault is improving, stable, or getting worse. Your coaching focus updates automatically.

What Makes a Good Swing Coach

A good swing coach does not overwhelm you with information. They watch, identify the one thing that matters most right now, and give you a clear path to fix it. That is exactly what GolfCoach does.

The app does not dump 20 metrics on your screen. It tells you: "Your swing plane is outside the target line. Here is why that causes your slice. Here is a drill to fix it. Work on this until your next session." That is coaching, not just data.

And because GolfCoach remembers your history, it knows whether the fault you saw today is the same one from last week or a new issue. That continuity is something even human coaches struggle to maintain across multiple students.

Frequently Asked Questions

What angle should I film from?
Down-the-line (camera behind you, aligned with your target line) is best for swing plane and path analysis. Face-on (camera facing you) is best for rotation and weight shift. GolfCoach supports both angles.
How many swings should I record per session?
2-3 swings per session is enough for the AI to identify patterns. Quality matters more than quantity. Focus on the drill GolfCoach recommends between recordings.
Can the AI detect my specific fault?
GolfCoach evaluates four key mechanics and their interactions. It identifies whether your plane is inside/neutral/outside, whether rotation is good/limited, whether your head is stable/excessive, and whether tempo is smooth/rushed. Most common amateur faults show up clearly in these metrics.
Does it work for all club types?
Yes. You can tag each swing with the club you used (driver, irons, wedge). The AI adapts its expectations based on club type, since a driver swing naturally differs from a wedge swing.
