EARLY PREVIEW

A lens.
Not a label.

ONDO explores Korean Saju as a traditional cultural practice for reflection and entertainment. It is not a scientific personality assessment, professional advice or a promise about the future.

Your choices stay yours

AI interpretations can be mistaken, and different practitioners may interpret the same chart differently. Do not rely on a reading for medical, legal, financial or other high-stakes decisions.

Free beta

This preview is for adults aged 18 and over. Payments and subscriptions are not enabled. AI availability depends on service configuration, and daily limits may apply.

Calculation conventions

The beta uses local civil birth time, a midnight day boundary and solar-term year and month boundaries. It does not apply true-solar-time correction. Timing estimates and analysis require expert validation before professional use.

Service readiness

Features may change during development. Operator and support information will be added before public launch.
