In Korea, many people explore their personality and life patterns through something called “Saju” — a traditional system similar to astrology, based on birth date and time.
Prism Saju reimagines this concept in a more playful way.
Instead of a single interpretation, your destiny is expressed across multiple different worlds — each offering a unique narrative of the same underlying traits.
It’s less about predicting the future, and more about exploring yourself through a cultural and storytelling lens.
Just try it and see your world.
• Multiple story worlds based on the same birth data
• Personality interpretation through narrative formats
• Traditional Korean astrology (Saju)
• Lightweight and easy to explore
• Explore your personality in a new, story-driven way
• Discover Korean astrology in a simple and fun format
• Try something different from typical personality tests
• Share and compare results with friends
• Casual self-reflection and curiosity-driven exploration

Hey everyone 👋 In Korea, there’s something called “Saju” — a traditional system similar to astrology, based on your birth date and time. Growing up, I found it interesting that even people who didn’t fully believe in it would still say things like, “this part is weirdly accurate.” So I started thinking: What if this wasn’t presented as a single, fixed interpretation — but as something more flexible and exploratory? That’s how Prism Saju started. Instead of giving you one answer, it shows your underlying traits across multiple different worlds. Same data, different interpretations. It’s less about predicting your future, and more about exploring personality through a cultural and storytelling lens. Would love to hear what you think 🙏
Really creative take on astrology. I love the idea of interpreting one birth chart through six completely different narrative worlds — it turns what's usually a single static reading into something you actually want to explore. The "Life RPG" and "Future Letter" perspectives especially stood out to me. The dark UI with glowing card animations feels polished and sets the right mood. As a fellow solo builder, I can tell a lot of thought went into the experience design here. Nice work!
