In my opinion, @joker_josue makes a valid point. It is difficult to differentiate between content generated by ChatGPT and text that has been translated from a non-English native language to English or edited using ChatGPT and similar tools. I do not think there is a clear way to distinguish between the two, and I suspect that most AI Content Detectors would classify the text as AI-generated, even if it is not the case.
In the example of my post, when using one of the recommended detectors, it indicates the 4 options written by human. What is correct.
But I found it interesting that in the first 3 options he was 97-99% sure he was human. While in the last option (Written with the help of: ChatGPT & Grammarly) it identified as 100% written by human.
That is, if the person uses the right tools, with half a dozen clicks and one or another adjustment, the detectors are no longer effective.
Using an automatic system to detect text written by AI will only be effective if that AI uses a standard element. Thing, that doesn't happen. Now, you can use terms or expressions that normally a human, in a written conversation, is not used. And this can be an element that draws attention, but even so, you have to be careful about classifying it as done by AI or not.
