annoying
Grammarly inserted itself onto my computer in about 2015 and hasn't left since, I often get pop ups telling me that I can pay to see how I could have better written something. Or asking me to Americanise my writing, or add useless commas everywhere. I wanted it for spelling mistakes but now coming to think of it, it's just another annoying thing that pops up trying to sell me the pro version any time I write something
