AI × PSYCHOLOGY
A couples app

your relationship
with psychology and AI.
An AI counselor gets to know your relationship.
From regular messages to helping you share your feelings and settle fights, it's there for both of you.
Regular messages
The counselor looks at how things have been going between you and sends a morning message with advice that fits where you two are right now.
Auto-join
The counselor gently checks in on how each of you is feeling. In your shared counseling room, it can also join the conversation to help (COUPPLY PRO).
Sort out and share feelings
Thanks, love letters, requests, apologies, seeds of frustration, and jealousy. Sort out how you feel with an approach based on cognitive psychology, and the counselor helps put it into words that will land well with your partner.
Court
The counselor plays the judge, hears both sides of your fight, and helps you settle it fairly, with a verdict, a split of responsibility, and the reasons behind it.
