I can relate to this. I use Grammarly, and find it helpful, but I do ignore about half their suggestions. I often use words that aren’t in the dictionary in my attempts to add some humour. I always turn it off for site like Facebook where I am not concerned with my grammar at all and just want my comments to be how I talk. It also annoys me that the green “g” often situates itself at the end of what I am typing and I can’t see or change what is underneath it.
