FlexChords – chords for any YouTube song, from a model I trained

About

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/-cbL3L3UnGs It's still a work in progress. I'd love to hear where it gets chords wrong and any other feedback.
