A language model wrote this post. I directed it, but I didn't rewrite a single sentence by hand. Then I ran the draft through a small ruleset called Alchemy. If the writing below doesn't trip your "this is AI" alarm, that's the entire point, and I'll show you the machinery.
Start with the alarm itself. You've felt it. A README opens with "In today's fast-paced digital landscape." A reply leans on the em-dash three times in two sentences. Something delves into something else. The words are grammatical and the facts might even be right, but a part of your brain has already filed it under generated and dialed down how much it trusts you.
That reaction is real and it's getting sharper. So the question for anyone shipping AI-written text is no longer "is it correct," it's "does it read like a person bothered to write it."
