March 12, 2021Which AI content detector is Reliable
None of them. I would testify in court to that fact. There's a 0% probability of success. It is literally an AI just pulling nonsense out of its ass and someone selling it. I can make an AI content detector that will beat or match any on the market and that means nothing. More on reddit.com

June 2, 2023Does anybody else find AI content detectors to be really sketchy and misleading?
These "AI detectors" work by looking for high "perplexity," which is the presence of relative randomness in the text, in some relevant sense. What I've found is that "perplexity" is strongly negatively correlated with clarity. If you feed in some typical freshman English crap, they'll say it likely wasn't written by an AI, because it's confused rambling nonsense. If you feed in an Isaac Asimov science article, it's going to say an AI wrote it, because Asimov is (famously) able to write clear, coherent articles based on the organized thoughts of a powerful mind. The ability to write well is less common than it used to be, but I certainly hope we aren't headed for a future where we not only tolerate, but actually require students to write badly, in order to get past the AI detector. There's also a difference between using AI as a super-advanced version of the Microsoft Word grammar checker, and using it to actually provide the content of the assignment. The latter is plagiarism (or at least some form of cheating); the former is not. But the AI detector tools seem to be mostly targeting the former. More on reddit.com
