My apologies, I take back what I say but I tested it on https://kouh.me/ai-text-detector because that's the only AI text detector which doesn't have some word limit. (It was recently submitted as a show HN[0])

I then tested it on pangram and gptzero and pangram does say 97% human and only 3% AI and GPTzero says 100% human

For some reason, my AI spidey sense had activated and I used the new AI text detector and it had a false positive maybe.

But I was wrong and since this is written by human, now I will read it :-D

An interesting observation that I have made here is the amount of stickiness that Pangram and others can have. I tried a new AI text detector and it failed and because of it I falsely accused someone of AI writing. Now I would prefer not to use that. So AI text detectors have this sort of effect where they have to be really effective and false positives/negatives can change a lot of things/interactions.

My apologies though once again that I said that it was AI generated when it wasn't!
