I used it all the time as a guide but I also used the free version. When I was an Editor I would suggest to people that they use the free version of Grammarly or ProWritingAid. I had the paid version of PWA and those two were like siblings that didn't know how to play nice.

One would say to do one thing and I'd make the change and then the other one would have a fit and tell me to change it back. Uck.
