I play guitar, and chord charts online were often wrong or oversimplified for the songs I wanted to learn, so I built FlexChords. You can edit the detected chords, transpose, and export to MIDI.1-minute demo: https://youtu.be/-cbL3L3UnGsIt's still a work in progress. I'd love to hear where it gets chords wrong and any other feedback.

Could you build this?
Partial The editor, transposition, and MIDI export are vibe-codeable, but automatic chord recognition from YouTube audio needs a trained audio model and labeled chord data.
What it would actually take: The pipeline is YouTube audio extraction, source separation, beat and chroma feature extraction, and a chord-classification model, then an editor on top. The hard part is accuracy on real recordings, which requires labeled training data and ML expertise in audio signal processing. Ongoing work on YouTube download reliability and licensing is also needed.
