There are tools to detect this. You can find them by simple Google search. <

There are, but at least the ones Ive tried out ,that allow you to perform a free trial online, have seemingly very poor results detecting GPT-3 based Chat GPT text, and thats just feeding a direct output as input to the detector, with no spinning or customization at all in between to even try to throw them off their tracks. There are a few additional ones I would have been prone to try, but they required subscription and payment (a no go at this stage).
Were the outputs to eventually have an inbuilt
digital watermark, there could be an easier basis to detect AI generated type text, but even so, each company will have used their own method to generate the (potential) watermark, and Im pretty sure that adding a step or two in the end-users pipeline would largely degrade the watermarks persistence and utility (though that requires some minimal effort on the users side, which is not a done deal).
Indeed, not all services are reliable and free at the same time. Even if that were the case, we simply couldn't go around to each forum post and test if it was written by AI. There are some hints that may indicate that a post was written by AI, but my main concern is that services such as ChatGPT may even create duplicate content if the same parameters are used, and it may cause post bursts and spam issues since it is capable of producing a wide variety of posts within a short period of time. AI may not produce low-quality posts, but it'll definitely create non-engaging discussions, which in some cases, may be worse than plagiarism.
