> the funniest part of these AI detectors is that if I were to upload any of einstin's paper's they will all be flagged as AI-written.

Have you tried doing that or even read the article?

The article says that their detector flags 0.4% of pre-AI papers as AI-written.

If I paste the first page from this paper (https://www.fourmilab.ch/etexts/einstein/specrel/specrel.pdf) in https://unslop.run/app, I get a 0% chance that it was AI-written.

Even the translated version of the field equations paper has a 1% match only. Which I expected to be a tiny bit higher but still near 0.
