Frequently asked questions

An AI divination platform where 15 systems — BaZi, Zi Wei Dou Shu, Da Liu Ren, Qi Men Dun Jia, Najia I-Ching, Plum Blossom, Xuan Kong flying stars, Eight Mansions, Western astrology, tarot, numerology, Human Design, Vedic astrology, Xiao Liu Ren and Auspicious Places — are cast by deterministic engines, and AI interprets only within the chart.

Most AI fortune apps let the language model "calculate", and the charts are often wrong. Suan's iron rule is: engines cast, AI interprets. Every chart is computed by verifiable code; the AI then reads it. Each reading is also a vote among systems, and the verdict states that vote plainly.

Honestly: the chart is exact — casting is deterministic and reproducible. The interpretation is a reference — a millennia-old cultural framework applied to the chart's facts, meant to clarify a situation, not to decree fate. It never replaces medical, legal or financial advice.

Four reading types: Life (your chart's fabric), Luck (this year and the near term), Matter (one concrete question — stay or leave, sign or wait, timing) and Bond (a relationship between two or more people). Matter readings are the deepest: four casting systems vote, with one unified timing window.

Credits called Suanzi: 3 free on sign-up, more for inviting friends (both sides get credited). Readings deduct by actual usage; top-ups at $25/$50/$100 with bonuses on larger tiers. Light features like the Quick Sign are free.

Birth data is used only for casting. Shared verdict cards are automatically scrubbed of names, birth times and places. The Auspicious Place pin is computed on your phone; location coordinates are never uploaded.

The written conclusion of a reading — a shareable card with a headline judgment and the seals of the systems that actually voted in the consensus. The number of seals is an engine fact.

A direction, terrain and time window derived from your chart's favorable element, the month's flying stars and the traveler's formula. It only appears when at least two of the three methods agree — otherwise Suan stays silent rather than guessing.

Six: Traditional Chinese, English, Korean, Japanese, Thai and Arabic — with cultural localization such as Kyūsei Kigaku for Japanese users, Tojeong Bigyeol for Korean users, the Birthday Buddha for Thai users, and Vimshottari dasha for Vedic readings.

Really cast. Da Liu Ren sets the heaven-earth board from the monthly general and hour, derives the Four Lessons and Three Transmissions through the nine classical rules, and assigns the Twelve Generals. Qi Men fixes the board from solar terms and lays out stars, doors and deities. All of it is table-driven code you can check against the classics — the AI contributes zero calculation.
