Sidera takes your date and time of birth and runs it through Saju — Korea's legendary four-pillars reading — then AI writes it up as a report that's weirdly specific, screenshot-worthy, and actually fun to read.
Entertainment content, not advice. 18+. The fine print, unhidden.
What's Saju?
Saju (사주) means "four pillars" — the year, month, day, and hour you were born. For a millennium, Koreans have read these four coordinates like a character sheet: your temperament, your patterns in love, your relationship with money, your seasons.
It's a cultural institution — the thing you check before a first date, a job change, or a new year. Sidera brings it to the rest of the world: AI interprets your pillars and writes you an original, personal report in English. No appointment. No incense. Just the read.
