Hi Product Hunt! 👋
I'm Larry, and ZWDSIN is the first project I ever built — I started it to learn programming, and somewhere along the way it became a real product.
Zi Wei Dou Shu ("Purple Star Astrology") is the deeper, lesser-known sibling of BaZi in Chinese astrology — a 12-palace chart system that's been used for over 1,000 years. Most existing tools just draw the chart and leave you staring at a wall of Chinese astrological jargon.
ZWDSIN does three things differently:
1. Computes your chart locally with true solar time correction (your birth longitude actually matters — most calculators ignore it)
2. Lets you ask AI specific questions — "should I take this job offer?", "what does my chart say about relationships this year?" — answered from YOUR actual chart, not generic horoscope text
3. Works in 5 languages, so you don't need to read Chinese
First reading is free, no signup. Would love your feedback — especially from anyone who knows Western astrology but has never tried the Chinese system.

tried the free reading out of curiosity and the love section actually picked up on something pretty specific from my chart, like way more detailed than i expected for a freebie. the plain language part is legit too, no mystical jargon to wade through.

@tark47535438267 Thanks for giving it a try, Tarık — I’m really glad the reading felt specific without drowning you in jargon. That balance is exactly what I’m trying to get right. Without sharing anything personal, was it the timing, personality pattern, or relationship dynamic that surprised you most?

honestly love the concept and the free first reading hook is smart, but one thing i'd want is a way to compare two charts side by side for compatibility readings. right now you only get your own reading, but most people coming for love stuff want to see how they line up with a partner's chart. would basically turn it into a two-sided tool instead of just solo.

@sra82hg Thanks, Sıraç — a two-chart compatibility view makes a lot of sense, especially since relationship questions are one of the main reasons people try ZWDSIN. Would you find a side-by-side summary more useful, or an AI Q&A that can reason over both charts together?

Love that you're keeping the language plain instead of drowning people in jargon. One thing I'd love to see is a side-by-side comparison feature that lets you run two birth charts together to check compatibility timing, not just individual readings. Would make it way more useful for couples planning big decisions.

@yasinerhalg3oh Appreciate the thoughtful suggestion, Yasin. Compatibility timing is a particularly interesting angle — not just whether two charts match, but how the relationship changes during different periods. For major decisions, would you care more about choosing dates, understanding difficult periods, or long-term compatibility?
