FYI I played with a few AI detectors and more often than not my own writing is flagged as AI generated, even though it isn't. These generators look for 'randomness; and 'variance' in the language and structure, something a good writer seeks to eliminate in their writing. The detectors throw up too many false positives, and judging using ' belief' is not a useful approach either. I did some digging and compare Medium's approach to Google in this article ... https://andywoodhq.medium.com/using-ai-generated-content-on-medium-9d15bec3f3f
