The Only AI Tell That Doesn't Need a Detector

comment on the last piece fits here too. Rephrasing his own English for flow, after 6 to 20 hours of writing the argument himself, isn't a case of ordinary ideas dressed up as brilliant ones. It's someone's real thinking, translated. Nothing in that process produces the register mismatch PG is describing. A classifier flagged it anyway, at 97% confidence, on a post from 2017.

The other thing PG's test doesn't need is a platform. Chris Best's whole pitch for that readers already discount slop on sight, than it is to anything Substack shipped this week.

I don't think that makes the tool pointless. Most readers aren't reading carefully, most of the time, and a feed moving fast enough rewards that. But it does mean the two approaches are solving different versions of the problem. One scales an ear. The other replaces it.

I know which one caught real writing and called it fake, and I know which one would have let it through. Diction that matches the idea isn't something a classifier trained on hard negatives is built to notice. It's something you have to actually read for.
