My wife is a freelance writer/translator, and so many of her clients check her work with so-called AI Checkers, often making her rewrite her work until it scores below 30% (even if it was 100% her work in the first place).

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.
