Fluent is not the same as true. That is the whole problem with AI-assisted content, and it is why "does this sound like AI" is the wrong question. I gave Gemini one prompt: "write me a blog about medicine." It came back polished. Then I ran it through anti-slop, the skill I built, and it returned 14 defects with a verbatim quote and a mechanical test behind every one. You can run three of those tests by hand right now, on anything you published this week. 1. The deletion test. Cut a sentence. Say out loud what was lost. If the answer is "nothing", it was padding. 2. The inversion test. Negate the claim and write the negation out in full. "This plays a crucial role in the industry" becomes "this plays no role in the industry." If nobody would ever assert the negation, the original said nothing. 3. The attribution test. Every "studies show", "experts say", "industry reports" gets resolved to a named source, and then you check that the source says that specific thing. There is no third outcome. It resolves or it does not. Most AI-assisted marketing copy fails all three, and so does a lot of human-written copy. That is the point. The tool never tells you who wrote something. It tells you which claim does not hold up, which is the only thing you can actually fix.

If nobody would argue with the opposite, the headline is empty.
