As far as I could tell, for Sapling.ai everything would be AI if there were very few grammatical errors in the text. However, the absence of errors cannot be evidence of the use of AI, and at the same time, grammar-checking tools are becoming more and more perfect every time. Additionally, I can add that the use of words that AI loves is becoming a normal phenomenon for most people since most websites and news on the Internet pass their materials through a robot, and we are simply used to using these words more often. As a result, it is difficult to say who picks up frequently used expressions from the Internet faster, a bot or a person.
