I am pretty good at detecting even partial use of AI, but then again, I work in my day-job on stuff AI these days, so I guess I have an advantage. There is one more thing though. If someone thinks an article is AI generated it means it's either about a very boring or generic topic. I regularly test my own stories in AI detectors. There's never any indication that might even be remotely AI generated, but when I'm suspicious about someone else's story, it 90%+ of times confirms my suspicion. Why? Because I don't write about generic stuff, nor am I boring when I write. I have a style and I stick to it. Those who use AI, don't have a style, or those whose stories come up as AI generated even if they're not, they should think about improving their writing. Your articles never gave me the impression of being AI generated, btw.
