The SajuFlow Story
Why we built 22 AI Saju masters
Bringing Korean Saju to the world, in its own depth
Minsung Lee · Founder, Seoul
Hello. I am Minsung Lee, founder of SajuFlow.
Korean Saju is 1,500 years of precise astrological wisdom — deeper than your typical Zodiac reading. Yet most global astrology apps stop at sun-sign generalities. Why is this Korean depth not reaching the world in each country s native voice — that single question took me a year.
We tuned 9 languages like scholars, built a 7-Layer Truth Defense against hallucination, and gave the AI 22 master characters. We build a service that gets better every day.
— Seoul, with care
🧙 22 AI Saju masters — why 22?
The 22 He/Chong/Hyung/Hae relationships of Saju, embodied as people. Each character is modeled after a real consulting Saju master.
“ Knowing others is wisdom; knowing yourself is enlightenment. ”
