a) I hate you.
b) I’m a (former/occasional) professional journalist and editor. I’d also somehow completely missed out on this entire product line. I’d never heard of grammar checkers until today, with the exception of the one built into Word, which I’d always disabled immediately after installing a new version. I was rather excited about the prospect of NLP having advanced enough for this to actually be useful to me from a professional standpoint.
So yes, I’m possibly more invested in the idea of this product offering than most happy mutants 
Now excuse me while I stock up on red pens to fling at you. I hope you realize you just did the literary equivalent of playing a piano piece and then refusing to play the very last note.
