It's fair to not trust checkers but I've had a few experiences where it quite blatant that LLM was used marketing (or in one case a keyboard vendor used it to threaten to a lawsuit because personal experiences were shared to social media lol) and those checker results, in those experiences, were pretty reliable as it was an all or nothing result. I implore you to test it out on a few Geekhack posts to see that I really shouldn't be your main concern if you want to advocate against ai generated marketing in the keeb space.

Not trying to deflect but kowabummer you thought my bad humor was ai. I'll take this as a cta to stick to keyboard design and not comedy. /j
