Yesi
Read full descriptionHide full description
The same fight again. The same "you never listen to me." Yesi is the AI advisor that truly listens to you both β first you, then your partner, then the two of you together. Because in the middle of an argument, nobody can really hear anyone. So Yesi takes a different path. HOW YESI WORKS 1. First, just you. Say what's really going on β no judgment, no interruptions. Your partner never sees this conversation. 2. Then your partner. Yesi listens to their side with the same privacy β without passing on a single word you said. 3. Then the two of you, together. When you're both ready, Yesi opens a joint session and guides it: one voice at a time, everyone heard, no one talked over. Maybe for the first time in a while. START ON YOUR OWN Partner not ready yet? Most couples begin exactly like this. Your first introduction session is yours alone β and it's free. Get to know Yesi, feel what it does for you, then invite your partner with one tap when the moment is right. WHY COUPLES CHOOSE YESI β Truly neutral. Yesi doesn't take sides. It cares about what you both said β not who said it louder. β It doesn't stop at talking. After every joint session, you get exercises made for the two of you β with follow-up, so change leaves the chat and enters your life. β Privacy, non-negotiable. Individual sessions are encrypted and yours alone β no third parties, not even your partner. In joint sessions, Yesi carries your needs, never your words. MADE FOR Dating, engaged, married or long-distance. Couples circling the same topic again and again. Anyone who'd rather talk before small hurts grow big. TYPE IT OR SAY IT Share the way that feels natural β writing or voice. Over time, you'll watch your relationship move. WHAT YESI IS β AND ISN'T Yesi is an AI relationship support assistant for educational and self-improvement purposes; it isn't a licensed therapist and doesn't replace professional mental health care. In a crisis, in situations of abuse, or in an emergency, please contact a professional or emergency services.
