Shuji's "末路診断" quiz runs AI once and needs no servers after launch

The design choice to pre-build every result is what makes the zero-cost claim possible. AI is used only on the maker's own machine while assembling the quiz, and the published site returns only static HTML and images. The text-writing AI was never allowed to produce numbers, so the probabilities could not drift. The quiz keeps its combinations at 200 or fewer so the volume of text, images, and pages stays predictable, and the author says the finished quiz has 174 result pages. The piece describes several pitfalls encountered during the build, including branch probabilities coming out nearly identical, AI talk in the prompt pulling the branches toward AI-related choices, and share images failing to appear until an absolute URL was set. The author says the build took half a day, but the harder part was what happened after publication: traffic fell from 28 visits in a day to 3 within 48 hours, and the pass-through rate to AI Contents Bank was 13%. That gap between building the quiz and keeping people coming back is presented as the real difficulty, and the stated response is a revision to add a link directly below the result page.
