> Specially from the perspective of non-native speakers.
Mind you, non-native speakers tend to involuntarily stretch and bend the language this way and that. It’s when somebody else in society uses that involuntary bending and stretching to mark and segregate foreigners that tools like Grammarly come handy. And, that’s my grudge with Grammarly: to me, most of its suggestions read as “you are not writing pureblood, your written mongrel will earn you the scorn of your betters.”
