Pangram is just some BS man can you please stop
It's baffling that people would rather call BS on me than try the actual tool being talked about.
How about you do this, write your own words on a topic, but use AI-isms in it. A few 'not X but Y' an a few EM dashes and watch it say you're text is AI written.
Writing using AI stylisms has nothing to do if a text is actually written by AI or not. The tests are mostly bullshit because just adding some informalisms in the text corpus tends to get it counted as non-AI. It's not detecting what you think it is.
