Yes I checked it...I am talking about a tool where you select the chord and it lists the notes like lets say you choose an Am chord it would show you that the notes that make up the chord are A, C, and E. Then it will show a fretboard and every a c and e on it. And you could pick custom notes lets say you wanted a chord that is made up of g a and f you will click those notes on the fretboard and it will name it for you and then tell you where else you could find those notes on the fretboard
