No PhD. No $30/month subscription. A computer-vision golf coach, vibe-coded in one week.
Swing It AI reads a golf swing frame by frame and shows you what to fix — the kind of app that used to need a computer-vision team and a subscription business behind it. Ours took a week.
Every golfer knows the problem: you can feel something is off in your swing, but you can't see it. The apps that can see it for you charge around $30 a month, every month, forever — for software someone else owns, trained on someone else's priorities.
Computer vision used to be a moat
Not long ago, an app like this meant hiring specialists. Pose estimation, model training, mobile deployment — a computer-vision team, months of work, and a budget that only made sense if you were building a subscription business to pay for it. That moat is why the $30/month apps could charge $30 a month.
Swing It AI wasn't built by a PhD. It was vibe-coded: describe what the app should do, let AI write the code, test on real swings, repeat. The working app came together in a few days. Then came the part that used to be the hard part — and it wasn't hard anymore: training it on real swing footage, our own data, until the analysis was genuinely good. Total time from idea to an app we'd actually use: one week.
Build it, don't buy it
This is the part every business owner should sit with. You have a problem that's specific to your niche — your customers, your sport, your workflow. The old answer was to buy whatever off-the-shelf software came closest and live with the monthly fee and the compromises. The new answer is that a focused person with AI can build the exact tool in days and own it outright.
If a week of vibe coding can replicate a subscription computer-vision product, ask what it could do to the software bills — and the software gaps — inside your own business.

We built this ourselves. Your team could too.
This isn't an agency case study — it's our own build, done with the same AI playbook we teach in the room. Every business now has this option: your own people, shipping your own software. Send your staff to learn with us, or come yourself.
