I just checked this out. It's a good idea, but you have some major problems with your scale finder, specifically the scale degrees (i.e., letter designations for notes). It breaks the most fundamental rules of music theory by skipping some scale degrees and repeating other scale degrees using enharmonic equivalents. But that is incorrect and problematic. Examples:
C# Major: your scale finder returns: C# D# F F# G# A# C C#
This is not correct because it repeats the fourth (i.e., F and F#) and eighth (i.e., C and C#) scale degrees, but skips the third (i.e., a scale degree based on "E", in this case E#) and seventh (i.e., a scale degree based on "B", in this case B#).
The C# Major scale is actually: C# D# E# F# G# A# B# C#
The key signature has 7 sharps - one for each of the seven scale degrees (see your circle of fifths). Using your notes, there could be no iii (E# min) or vii (B# dim) chords. Instead you would have two different forms if the first scale degree (i.e., a I and a i-dim based on C# and C, respectively) and two different forms of the fourth scale degree (i.e., one based on F and another based on F#).
Another example is your C# melodic minor, which your scale finder identifies as: C# D# E F# G# A# C C#
This one has no seventh scale degree (i.e., based on "B"), but has two notes based on the first scale degree (i.e., C and C#). The correct notes are: C# D# E F# G# A# B# C#
This isn't just semantics. Triads, chord extensions, chord naming, the circle of fifths, sharps/flats, accidentals, etc. all depend on the correct usage of scale degrees.
EDIT: looking at it further, no offense but it's just awful. You completely skipped all the flat keys, and many of your sharp keys are not even close (e.g., A#). I highly suggest taking it down. It's misleading and will only confuse people who are already confused enough.
