Hey Product Hunt π
Cheonmyeongdang is a Korean Saju (μ¬μ£Ό, four pillars of destiny) AI that draws your birth chart and reads it in 9 languages β English, Japanese, Chinese, Korean, Spanish, Portuguese, Indonesian, Vietnamese, and Hindi.
I'm a solo founder (Korea, 1-person company). Built this because every astrology app out there is Western. Saju is 4,000 years old and nobody outside Korea/China can use it without learning Korean. So I wired SolarβLunar calendar conversion, true solar time, 24 jieqi solar terms, the whole stack, plus a GPT-style AI consultant on top.
What's free:
- Birth chart drawing (10 pillars, hidden stems, all of it)
- Compatibility (κΆν©) preview
- Daily fortune
What's paid:
- Daily pass β©1,500 (β$1) β unlimited AI consult for 24h
- Monthly β©29,900 (β$22)
- Annual β©287,040 (β$211, ~20% off)
Currently live in web (sajuapp.app) + Android (Play Store), iOS in review.
One thing I'd love feedback on: the AI consultant tone. I made it conversational on purpose because traditional Saju readings are dense and intimidating. Did it land for non-Korean users? Anything confusing?
Thanks for checking it out π happy to answer anything.
