The Problem

Getting useful feedback on your golf swing usually means booking a lesson. But most golfers only see a coach a few times a year. Between lessons, you're practising without feedback. Or worse, practising the wrong things.

Why I Built It

I started learning to play golf with a coach in 2025. Between lessons, I wanted a way to check whether what I was practising actually matched what my coach was asking for. I couldn't tell from feel alone, and watching slo-mo on my phone only showed me so much. So I built a tool that could measure what was happening at every key position. That tool became SwingLens.

Our Approach

SwingLens.golf uses computer vision and AI to give you detailed swing analysis from a phone video. Record yourself in slow motion, upload the clip, and our system extracts key frames, measures your body positions with pose estimation, and generates a coaching report covering every phase of your swing.

How the Technology Works

• Pose estimation detects 33 body landmarks in each frame, measuring angles for spine tilt, arm extension, hip-shoulder differential, and more.
• AI analysis reviews the measurements and images together, rating each swing position and identifying mechanical issues with severity rankings.
• Progress tracking stores your measurements over time so you can see exactly how your swing is changing.

Built for Golfers

This isn't a replacement for a great coach. It's a tool to help you make the most of your practice time. Get objective feedback on every session, track your progress with real data, and show up to your next lesson knowing exactly what you've been working on.
