AI has even infiltrated the response section of our articles. I detected several of those on my articles. Here is what you can do to protect yourself: install the copyleaks AI detector. You can use it on their site (https://copyleaks.com/ai-content-detector) or install their browser app (you then only need to highlight a text and you'll immediately know whether and to which degree the text is of AI origin). Copyleaks seems to be the same AI detector that Medium uses (though I have detected considerable AI content in some editors' posts of pubs that explicitly discourage AI use.

Your second option is to use zeroGPT.com. It has a nicer results page, but I tested it with texts that have been written 4 years before ChatGPT came online, and it marked a (very) small percentage as probably AI-written. That's why I don't fully trust it. I don't trust either one 100%, but whenever my gut tells me that a text has probably AI origins, they both seem to confirm my suspicions.
