AI detectors are such a scam. They work better on detecting the older version of AI, but anyone can bypass them with a few simple edits or changing the prompt to write in a different style.

I usually know if something is AI or not because it just feels off or if it's all information and no personal content. However, some are really good at editing AI, and it's very difficult to find unless they make the mistake of not removing an AI phrase or one of the common sentence structures that AI uses.
