I'm apparently not good at spotting it. I was put off by the overly dramatic presentation. It gets tiring that the author apparently finds this more exciting than I do, and writes like it's enthralling. I just assumed it was an excess of enthusiasm or the first experience with this kind of thing. If it's AI, I'm way behind the game noticing it.

idk why this is getting downvoted, I also got this sense, plugged it into Pangram and indeed, 80% AI-written score.

I guess that's fine, but after awhile I get a spidey-sense reading something that feels like a Claude session.
