Big question mark from me on that one. Seen Grammarly, read about Grammarly, come across the annoying You Tube Grammarly ads. Sorry, it doesn't make you a better writer, Reading more makes you a better writer. Omnivorous reading makes you a better writer. Carrying a notepad around to jot down thoughts and ideas makes you a better writer.
I loved your article. As a non-native speaker who has been teaching English for many years now and has written his fair share of articles for newspapers and magazines, I always welcome articles like yours. :-)
