Good to know.

Ari Fortune is a saju app: it calculates your Korean four-pillar chart from your birth date, time and place, and lets you talk through your day and your questions with Ari, an AI guide.

Your chart, calculated with a traditional saju calendar, and the flow of the day. Ari Fortune does the calculation itself; the AI turns the result into a conversation.

Choose “time unknown”. Ari reads everything that does not depend on the hour.

Clock time follows a time zone, not your town. In Seoul the sun is highest about 30 minutes after noon on the clock. Correcting for your birthplace's longitude and the sun's movement that day keeps the chart accurate.

Yes. Your day, your calendar and your chart are free, and you can ask Ari too. Half Moon and Full Moon give you more time with Ari.

Yes. Add a person, choose how you know each other, and see how you fit, with a reason for each part. You can also send a link so they enter their own birthday.

Birth details are used only to calculate and discuss your chart. Profile photos and conversation memory stay on your device, and you can delete your account in the app at any time.

No. Saju is a traditional way of reading, not a scientifically proven prediction. Use Ari's answers to think things through, and make important decisions yourself.

We are getting ready for iOS and Android. Store links will appear on this site at launch.
