Hi HN,

I built ChordCraft because I often struggle to find the right chords to support a melody, and opening a full DAW just to sketch an idea felt too heavy.

It's a free web tool that lets you visualize chord progressions (with Roman numeral/degree notation), customize voicings, and export the result as a MIDI file to use in your DAW later.

Key features:

Runs entirely in the browser (Web Audio API)

No login or sign-up required

Presets for standard progressions (like "Just the Two of Us")

Visual diagrams for Piano/Guitar/Pads

I'd appreciate any feedback on the UI or feature suggestions!
