Help me teach an AI to see guitar fretboards. Takes about 10 minutes. You'll need your guitar and a camera.
Hey! Thanks for helping 🤘
So I'm building this guitar app that can literally SEE your fretboard through a camera and overlay scales onto it in real-time. Like AR for guitar practice. The problem is, the AI needs to learn what a fretboard looks like from different angles, different guitars, different lighting. That's where you come in. All you gotta do is point your camera at your guitar and click 4 corners. The math handles the rest. I owe you tacos for this. Big time.
What can you help with?
Pick one (or do both if you're feeling generous):
Fretboard Photos: Anyone can do this — just need a camera and a guitar. Audio Recording: Only if you have an audio interface (Focusrite, PreSonus, etc.) plugged into your computer. Laptop mics won't work for this one.
📸 Capture Fretboard

Click "Start Camera" below
Click the TOP-LEFT corner of the nut
Corner points (click in order — order matters!):
① Nut + High E② Last fret + High E③ Last fret + Low E④ Nut + Low E
Try these angles (variety helps the AI learn):

🎉 You're awesome!
That's it! You just helped train a guitar AI. When this thing ships and can see fretboards in real-time, you're part of the reason it works. I'm getting you tacos next time I see you. Or pizza. Or whatever you want. Thanks for real.

🎸 Audio Recording
This helps the AI learn what each string and fret sounds like on different guitars. You'll play specific notes one at a time — the app tells you which one. Takes about 10-15 minutes. You NEED an audio interface for this (Focusrite, PreSonus, etc.) — laptop mics won't capture the detail needed.
