Grammarly at school

So at school we are allowed to use grammarly, but using it feels like a cheat for essays. I mean I like writing essays but the others might not so I don’t mind. They released this new thing called “Grammarly Go” and you put in a subject and it spews out a detailed response for you! I think that this could possibly write full essays for people, so I don’t want the teachers finding out.
