Yeah, this is not good at all. Even something arguably well-executed and compatible with "established" style heuristics, like Grammarly, will always be dubious

Yeah, this is not good at all. Even something arguably well-executed and compatible with "established" style heuristics, like Grammarly, will always be dubious, as they perpetuate the myth of linguistic prescriptivism weaponized by language pedants. All of whom are annoyingly, vocally, interminably incorrect. But this, this is just baldly idiotic.
