@syklemil@discuss.tchncs.de Just for curiosity I checked the text with an Ai detector. Mind you, this is not proof for or against, as I don't take these tools too serious too. They are Ai tools themselves.
https://www.scribbr.com/ai-detector/ says 0% likely is written by Ai.
https://stealthwriter.ai/ says 93% is written by Ai. This tool also shows the passages it thinks it is.
Remember, this is not a proof. But it looks suspicious to me. Test the services with text you know for a fact it is written by human (like yourself). And test is with some text you know for a fact it is output by an Ai (maybe directly ask an Ai for some text). In example the second tool gives me 48% written by Ai, for some text from my own blog post.
