What we promise. What we don't.

Saju AI Global is a tool for reading Korean Four Pillars (Saju 사주) charts using a self-translated, source-cited English RAG of three classical texts: 滴天髓闡微, 窮通寶鑑, and 子平眞詮.

Every reading is generated by an AI model (Anthropic Claude) grounded in retrieved classical excerpts. We show the citations so you can check our work.

We will never tell you which job to take, whether to marry someone, when to move, or any other life-altering decision. Saju shows the shape of your time; the choices remain yours.

The 5-Year Simulator (when it launches) compares two paths side-by-side. It does not recommend one over the other.

Readings are for reflection and self-understanding. They are not medical advice, legal advice, financial advice, or psychological diagnosis. If you are struggling with health, money, or mental wellness, consult a licensed professional.

If you don't know your birth time, we say so clearly. The hour pillar is set aside rather than invented. If a chart's structure is genuinely ambiguous, the reading will say so.

Don't scrape the service to rebuild it elsewhere. Don't use it to generate misleading readings about real people without their consent. Don't use the API endpoints for automated mass requests; we rate-limit, and persistent abuse leads to IP blocks.

Living Saju ($4.99/month) and 5-Year Simulator ($14.99 once) are paid tiers. Payments are processed by Paddle.com Market Ltd as the Merchant of Record.

Refund policy: 14 days, no questions asked. See the full refund policy for details, or email bchanghyeok@gmail.com to request a refund.

Subscriptions cancel immediately on request; you keep access through the end of the current billing period.

We aim for high availability but do not guarantee uptime. The service may go down for maintenance or due to issues with upstream providers (Vercel, Supabase, Railway, Anthropic, Google).

The service is provided ‘as is’ without warranty. We are not liable for decisions you make based on readings generated here. Maximum liability for any paid product is limited to the amount you paid in the past 12 months.

We may update these terms. Material changes will be announced on the home page for at least 14 days before taking effect.

Korea. Disputes resolved in Seoul courts unless local consumer law requires otherwise.
