Frequently Asked Questions

The eight saju characters are calculated from the birth date, calendar type and birth time you enter. Basic analysis accepts birth dates from 1900 onward for people who are currently at least 14 years old. Please check your birth information and solar or lunar calendar selection carefully.

However, the natural-language interpretation generated by AI is provided as a hypothesis, not a definitive prophecy. The result is a supporting tool for self-exploration; we recommend comparing it with your own real experience and taking what fits.

• It avoids definitive statements. Every output is unified in a "there's a chance you may be X" tone rather than "you are X."
• No deficit frame — instead of calling something a weakness, it describes "energy flowing in a different direction."
• It translates saju terms into everyday language . Unfamiliar terms are unpacked into everyday expressions or annotated in parentheses.
• A 5-part structure — innate energy → possibilities → saju composition → self-check → next steps.

For a detailed comparison, see the About page.

The features currently available are free. Basic and detailed analysis, the current day’s reading, and compatibility do not require sign-in.

Members can use MBTI comparison, refinement and tailored analysis, and keep basic analysis and daily reading history. Guest history is not transferred automatically; sign in before starting a new reading to save it.

OQi’s hour analysis is based on Korea Standard Time, so if you were born outside Korea we recommend using just your birth date, without a birth time. Your innate temperament and the broad flow of your life come through with the birth date alone.
