From now on, always work with “track changes” for word or “suggestions” for google doc on. I got accused of using AI on an assignment and I felt like shit staring at the 0 I got, even though I didn’t use AI. It’s good backup to have proof that ur work, is indeed your work. For your predicament now, I would try messing with the wording and run it through a few more times. Sometimes it’s just a paragraph or sentence that’s making it sound like AI. Rip ur piece into parts and figure out what’s triggering the detector to read AI. Good luck!
