Finding suitable chords

I know it is possible for Scaler to find the chords in an existing piece of music, but if that existing piece of music doesn’t have any chords associated with it yet, as it is a melody written first before adding chords - that’s the way I ordinarily work ie melody first - chords second can Scaler suggest appropriate chords. I have lots of melodies floating in my head but trying to find the suitable or appropriate chords afterwards proves a problem for me. So if Scaler can do this that would greatly help my compositions. I can play the piano a bit, but because of a physical problem with my left hand I struggle playing chords.

If so how?
