Used it a couple of times (not spent much time making music recently). It took a bit of messing around to get set up at first but got it working, and then found they have detailed instructions for different DAWs here:

It works well, my musical theory is seriously lacking so it helps speed up the process significantly, means I can just jam away finding chords that I like that work together. I like to set the synth track to record and then play around finding chords I like, and then turn Forager off and just work from the recorded chords, chopping and arranging the MIDI etc.
They have a 30 day money back guarantee so if your music/chord knowledge isn't great I would give it a go
