By skyforbes Im writing a grad school motivational essay (why this school); I put it into an ai detector just because and this is the feedback I received. Absence of grammatical or stylist errors and coherence apparently means that it's AI. So for an essay to not be AI today it has to be stylistically convoluted, not entirely coherent and have some slight grammar error I guess. And the thing is it's not like the essay I wrote is like top level writing coming from an incredible writer, it's just that I'd say it's basic logic to make your motivation essay coherent or without mistakes haha.
