If you're relying on these tools, please know that they're not accurate. At all. In fact, they're a waste of time. As an example, I pasted the first three paragraphs of the Declaration of Independence into one of these checkers, and the result: 100% AI generated via ChatGPT.
Edit: removed link to AI Checker site, as I don't want this to look like an ad. If you want to check, google "AI Checker", and test yourself.
True, people are putting too much trust into the checkers.
If a document is used to train an LLM, that means that an AI checker would be more likely to give a false positive that the document is written by AI?
I guess it depends on the AI checker.
I would think that that LLM, after generating the fragment "When in the course of.." would just be a bit more likely to generate "human" as the next word, yes?
