Free Usage Limits
Chart building and AI readings are two independent limits, both on a rolling 24-hour window from first use. Out of chart builds? Pay 9★ per extra. Out of free readings? Upgrade to a paid oracle.
Guest (not signed in)
Signed in
- Rolling 24-hour window: each slot frees up exactly 24h after use, not a midnight reset.
- Limits are tracked per device/browser, not per account. Logging out and back in, or switching accounts on the same device, does not reset your used count.
- Re-reading the same tab creates a new reading (history is never overwritten) — a paid tier is charged again, a free tier uses another daily slot.
Why the Difference?
Why does Grand Oracle cost so much more?
Grand Oracle runs our deepest AI reasoning model. Each reading processes thousands of "reasoning tokens" to cross-check the Four Transformations and chart patterns before answering, so its actual server cost is significantly higher than Scholar.
What happens after I run out of free readings today?
Chart building is free for 1 chart/24h as a guest and 3/24h when signed in; past that, pay 9★ per extra chart, unlimited times. Free Small Boy readings run 1-3/24h depending on sign-in; once used up there is no paid top-up for free readings: upgrade to Scholar or Grand Oracle instead, both with no daily limit, only a Star balance requirement.
How does Star (★) work?
Star is our utility point system for paying AI compute costs, at 1★ = 1,000 VND. New accounts get 19★ on first sign-in, exactly one full Scholar reading, not a token amount that buys nothing. Need more? Top up by package; packages from 180,000 VND up include bonus Stars.
Who should I select to read my chart?
Quick daily overview of your 12 palaces, choose Small Boy. Solid analysis of your ruling stars and basic Four Transformations for guidance, choose Scholar. Major life decisions (marriage, investment, career) needing deep insight into your major cycles, Grand Oracle is your ultimate choice.
