“Opposites attract” is mostly a myth for long-term relationships. Growing up between countries, cultures, and school systems is a real starting point for this app - it's why you'll see the countries your parents are from, where you grew up, and what you speak. But it's a starting point, not the whole match. Here's what the research says actually predicts whether two people last, and how this app is built around it.
Personality complementarity - the idea that a planner needs a spontaneous partner, or an introvert needs an extrovert - barely predicts relationship satisfaction. What actually predicts it: shared values, similar life goals, and matching attitudes toward money, religion, politics, and family. Two people who agree on where they're headed do better than two people whose personalities happen to balance each other out.
That's why this app doesn't ask you to fill in a personality quiz. It has an AI interviewer talk to you instead.
People are unreliable narrators of their own traits - ask someone if they have an anxious attachment style and you'll usually get a guess, not an answer. But ask someone to tell the story of how their last relationship ended, and the way they tell it - do they take ownership, do they externalize everything, is there any compassion left for the other person - reveals far more than a self-rating ever could.
The interview asks for stories, not self-assessments, across a few areas that the research ties most closely to long-term satisfaction:
Values & life goals
Where you want to be in five years, how central a relationship is to that, and what role family plays.
Conflict style
How you actually handle disagreement - the Gottman research points at contempt versus specificity, and whether repair gets attempted at all.
Attachment patterns
How you respond to distance and silence, and how you narrate the way past relationships ended.
Growth mindset
Whether you think compatibility is something you find already-formed, or something you build.
It doesn't take what you say at face value - every insight is extracted with an explicit confidence level, based on how clearly the story actually supports it. Vague or one-off answers don't get turned into strong claims about who you are.
When you're matched with someone, the explanation you see is grounded in what you both actually said - not a generic percentage. If it says you're compatible on family, that's because of something specific each of you described.
A good match is only half of it - who you're actually talking to matters more. A few things we do to help with that:
None of this replaces your own judgment. Verify who you're meeting however you're comfortable, meet the first time somewhere public, and tell someone where you're going.
