Key Points

A 9-handicap golfer built an AI “golf coach” after paying for lessons that gave conflicting diagnoses and stalled his progress.
He developed FlushedAI to analyze uploaded swing videos by extracting key frames and breaking down contact, ball path, club face, tempo, and body sequencing, then recommending drills targeted to the single biggest fault.
The app also tracks logged practice sessions (e.g., speed, smash factor, miss patterns) to update the user’s focus over time rather than offering generic drills.
FlushedAI adds social/golf-utility features including a global course map for logging sightings and a wagering system that uses AI to scan scorecards and settle bets.
The developer describes key lessons learned: generic vision models were unreliable without golf-specific fine-tuning, the tool should support practice rather than replace coaches, and the initial launch should have focused on the swing analyzer first.

I am a 9 handicap from LA who spent way too much money on lessons over the last few years.

Every coach told me something different. One said my takeaway was flat, the next said I needed more hip turn, a third said my shoulders were fine but my hands were late. I stopped knowing what to believe, and my handicap stopped moving.

About a year ago I started building what I actually wanted: an AI that watches my swing, pulls out one specific fault per session, and gives me a drill I can do on the range that night.

Not a generic YouTube drill, a drill that matches what it saw in the video. I wanted it to remember what we worked on last time. I wanted it to know when I had actually improved.

That project is now FlushedAI. It launched on the App Store this month and we filed a patent on the coaching system in March.

What it does:

Upload a swing video. The AI pulls the key frames and breaks down contact, path, face, tempo, and body sequencing.
It writes you a short summary in plain English, plus 3 drills tied to whatever the top miss was.
You log sessions (speed, smash factor, miss patterns) and it updates your focus over time.
There is also a map with 24,000+ courses worldwide where you can log sightings with friends and a wagers system for golf bets with your crew (AI scans the scorecard, settles the bet).

Things I got wrong along the way:

First version used a generic vision model. It was confidently wrong about everything. Lesson: general AI is not a golf coach. We had to fine tune on actual swing footage with a PGA pro labeling it.
Tried to replace the teacher. Bad idea. The tool is better as a daily practice partner between lessons, not instead of lessons.
Built too much at launch. Shipped the swing analyzer, course map, wagers, and drill library all at once. Should have shipped swing analyzer alone and let the rest follow.

Ask me anything. Happy to run a free swing analysis on anyone who drops a video in the comments, no app download required. Also giving out free Premium codes to the first 50 people in this thread who want to actually use it.

Not trying to sell anything here. Mostly curious what the crowd thinks is missing in the current crop of swing apps.
