Hi Product Hunt, I built Fretboard Lab because chord lookup is not the same as choosing a voicing. When you type Cmaj7, Am7, Dm7b5, a slash chord, or a roman numeral progression, the real question is not only “what notes are in this chord?” It is “which playable shape fits this song, tuning, hand position, and next chord?” Fretboard Lab is a local desktop chord voicing workbench. It generates multiple playable guitar shapes, exposes position, span, open strings, difficulty, barre details, and tuning context, then lets you export diagrams for practice sheets, lessons, or writing notes. There is a free community workflow and a $19 lifetime professional license for larger export/handout workflows. I would love feedback from guitarists, teachers, arrangers, and songwriters.

Which chord progression or tuning should I test first?

I m launching Fretboard Lab today and I d love practical feedback from guitarists, teachers, songwriters, or anyone who builds chord sheets.

The product is for a specific problem: a chord symbol alone is not enough. Cmaj7, Am7, Dm7b5, slash chords, and Roman numeral progressions can produce several technically correct shapes, but not all of them fit the hand, tuning, fret span, open strings, or the next chord.
