SAI ANALYSIS REPORT

HOW SAI SEES YOU

The decisive realist

PROVES IT BY DOING

You trust actions over words,
and once you are sure, you stay.

You hold things in until they surface all at once. What convinces you is not a nice speech, but someone who is simply there.

You say you speak your mind, but you usually drop a hint first and wait.

Questions people ask us

Frequently asked

SAI launches in South Korea first. If you're somewhere else, join the waitlist and tell us where you are. Matchmaking only works when there are people to match with, so we open a new country once enough people there are waiting. You'll hear from us the moment that happens.

There's no endless swiping. An AI trained on couples who stayed together scores compatibility across values, conflict style, attachment and more, then introduces two people a week and explains why each one fits. You spend your attention on people worth meeting instead of scrolling past hundreds.

Neither. Compatibility is scored from what you actually say in conversation — how you handle conflict, how close you like to be, what you want long term. It's psychology, not star signs.

People in their late twenties and thirties who are done with matches that look right on paper but never click. If you're looking for something that lasts rather than something casual, this is built for you.

Every account is verified by phone number, so profiles belong to real people. Contacts, schools and workplaces are blocked from your matches, profile photos can't be screenshotted, and personal details are revealed gradually as you get closer.

Signing up, your weekly introductions and the compatibility reports are free. You only spend ink when you send a like — and if the two of you actually meet, all of it comes back.

We'll email you when SAI opens where you live. That's it — no spam, and your address is used for nothing else.
