Sajumoon is an AI Saju consultation for people who finish a reading and still wonder what to do next, and for anyone who wants to sort through a worry against their Four Pillars chart. It isn't a horoscope that ends with a reading. Each session ends with one concrete action and a deadline. Enter your birth date, birth time and gender, and your Four Pillars chart is calculated; then you talk through what's on your mind. When the deadline arrives, a check-in card on the home screen asks how it went, and your answer (did it, did a little, didn't) opens the next session. Ask several counselors the same question and two or three of them reach different conclusions, rebut each other, and summarize what they disagree on. When an answer has a basis, it shows which chart elements it relied on, such as the day master, the Ten Gods and the Five Elements. The chart engine uses exact solar-term times, lunar and leap-month conversion, and the late-night hour rule. The Android app is on Google Play, and the web app is live at saju.tez.kr. On iPhone and desktop, use the web app. Today's Iljin and a quick view of your chart are free, and so are your first three Q&As. After that, consultations use tickets, which you can currently top up in the Android app, and tickets don't expire. AI consultations only run after you agree on the consent screen the first time, which sends your chart details and conversation through our server to OpenAI; you can withdraw consent in settings. Sign up with Google, email or as a guest, and you can delete your account. Sajumoon is AI content based on traditional Korean Saju. For important decisions about health, law or money, talk to a professional.
