Being a novice, I use the free software PC program without hesitation. In that I often have a number of unconventional words, or even will use punctuation for emphasis, if I don't like its suggestion I'll simply disregard it (of which there is a discard the suggestion button).
Although it might not be ideal except for us literary ignoramooses, I find it helps me to often rephrase something looking at it in a different light. If the suggested change works for me, I use it, if I didn't realize it was an error, I look it up further and learn one way or the other. If I don't like the suggestion, I don't use it.
My process (having just started using it and
Slick Write ) has changed since discovering it.
I write,
reread and edit,
reread and edit while trying to reduce sentence sizes,
note often repeated words searching the document for them and change as many as practical,
use grammarly and edit,
use slickwrite and edit,
use grammarly and edit,
let it sit,
reread again, edit as needed,
tell myself how great I am as I drink scotch... or rum... or, well, you get the point
Then post it and realize all I missed
