I wanted to get better at guitar. Specifically: learn where every note lives on the neck.
So I described what I wanted to an AI. Specific positions. Mic that listens. Feedback that teaches, not just confirms.
Thirty minutes later I had a working app.
But more interesting than the build was the iteration. "Show me where the note is before I play it." Done. "Lock the pitch to that specific string and fret — don't accept the same note on a different string." Done. "Give it a stop button and put it somewhere I can use it on any device." Done.
We're not finished. Riff mode, better feedback, maybe a progress tracker. The app will grow as my playing does.
