Melodist creates a chord pattern based on what you tell it with the style you choose.... it throws some chords together and it does create a melody line to be played with those chords.

I use this on some jazz tunes and it works just OK for that. I often have to edit the chords to get close to what I want.

Soloist will create solo tracks for that same melodist creation if I understand it correctly. I have used the soloist once or twice and stopped using it. I prefer to do my own solo work.

None of them will write a hit song for you.

You also have the option to let it choose a title for you.... again, that mostly isn't workable although I have used it.

Add nothing that adds nothing to the music.
You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
