Fair guess, but only half right. English is my third language, so AI polishes my grammar. The observations are mine. At 60 I take help with commas wherever I can get it ;)
It's against the rules to polish with AI. People won't care about your grammar, they want human voices.
Fair point about voice. The stories and opinions here are mine, from my own life. If some sentences come out too smooth, that is the tradeoff of writing in a third language with a helper. I understand the wariness.
