  • wwjd.family
    wwjd-family
     ● healthy

    The product is a pause. wwjd.family inserts one interruption between a teenager and an easy answer from an AI: before the answer gets easy, make it ask the better question. Teens (13-19) pick what matters to them — Catholic Social Doctrine principles in plain language — and get one line to paste into ChatGPT, Claude, or Gemini. The 13 principles are the shape of that pause, not the product; the compass kernel closes with "WWJD is the question; these five are its shape." The 1990s WWJD bracelet, but for the AIs teens talk to now.
