I mean, it literally and factually measures multiple your body's autonomous responses - all of which are provably correlated with stress. That's what a polygraph machine is. Saying it measures nothing is factually incorrect.
You can't detect "truth" from that, but you can often tell (i.e. with better accuracy than chance) whether or not a subject is able to give a confident, uncomplicated yes-or-no to a straightforward question in a situation where they don't have to be particularly nervous (which is why it's not very useful for interrogating a stressed criminal suspect, and should absolutely be inadmissible in court).
But everyone knows that it's not very reliable in almost every circumstance it's used. My point is that while only marginally better than chance, it's still better than chance, unlike the OpenAI's detector, which is significant worse than chance.
