XiaoSuanShi
Free AI Bazi Fortune Teller — 3000-year Chinese wisdom meets
Maker Introduction (Who are you?)
I'm a solo developer based in China, passionate about making ancient wisdom accessible through AI. I started coding 3 years ago and this is my first SaaS-ish product.
What's the product?
xiaosuanshi.com is a free AI-powered Chinese metaphysics platform. It offers:
Bazi Chart (八字排盘) — Enter your birth date/time → get a full Four Pillars destiny chart, Day Master analysis, Five Elements balance, 10-year luck cycles, and personalized life reading. All powered by AI (DashScope qwen-turbo).
Feng Shui Analyzer — Upload a photo of any room → AI identifies layout problems, missing corners, element imbalances, and gives practical remedies.
Guanyin Oracle (观音灵签) — A digital version of the traditional temple divination. Shake virtual sticks → draw one of 100 authentic poems from a Ming Dynasty temple, with AI interpretation.
Daily Fortune Cards — Draw a card every day, shareable with friends. Built with html2canvas for card export.
Book of Destiny (命之书) — Generate a personalized ~3000-word "life book" covering career, relationships, health, and yearly forecasts. Takes about 30 seconds to generate.
How did you come up with the idea?
I noticed a few things:
r/fengshui, r/iching, r/taoism collectively have 700K+ subscribers on Reddit
TikTok #fengshui has 34 billion views
Existing services charge $20-80 per reading
Most require booking a human master, which is slow and expensive
AI changes the game — what used to cost $50 and take 3 days now takes 30 seconds and costs me ~$0.01 in API fees.
The validation came from FateTell (fatetell.com). A 5-person Chinese team built almost the exact same product, reached profitability in 6 months, and is reportedly doing $100K+/month — all with zero ad spend, purely organic.
How did you build it?
Frontend: Vanilla JS + CSS, no framework. ~20KB CSS, fully responsive, zh/en i18n
Backend: Node.js + Express + MySQL
AI: Alibaba DashScope (qwen-turbo) with structured prompts constrained to traditional Bazi framework
Hosting: $24/mo VPS in Singapore (Ubuntu + Caddy + PM2)
Billing: Nothing yet — 100% free. Planning PayPal integration
The Bazi calculation engine was the hardest part. It uses traditional Chinese calendar math (solar terms, sexagenary cycle, Heavenly Stems and Earthly Branches). I ported the algorithm from a Qing Dynasty reference table — there's no npm package for this, you have to understand the math.

What's next?
SEO — Rank for "free bazi calculator", "chinese astrology reading" etc. Googlebot just started crawling.
Monetization — Thinking pay-per-analysis ($1-3 per reading) or monthly subscription. FateTell charges $39.99, so there's room.
More content — The "Book of Destiny" feature has the most potential. People love long-form personalized content.
Reddit/TikTok — Organic content marketing. Already tested TikTok, getting slow but steady traction.
Open source — Considering open-sourcing the Bazi calculation engine. Might drive developer traffic.
What do you need help with?
English copy review — Are the translations clear or confusing? I'm not a native speaker.
Monetization model — Free with ads? Pay-per-use? Monthly subscription? What's worked for you?
SEO strategy — How do I compete with established astrology sites that have been around for years?
Product Hunt launch — Worth doing? I already submitted once but want to do a proper launch with a following.
