my9ai is a 10-second AI personality test. Pick the 9 AI tools, models or features you actually use, and you get one of 16 four-letter AI personas (like MBTI for your AI stack), how rare it is, and a slightly rude one-liner about your picks. Then share the card on X, Instagram or Stories, and see how many AIs you share with a friend.

Right now it has a Halloween edition: "The 9 AIs that haunt me", with monster persona titles, a pumpkin frame and limited badges that retire after Nov 2.
