Hello, I'm a developer with a strong interest in dating psychology.

I built a web app that lets you analyze the behavior of someone you like and even simulate conversations with them.

1. Mind Reading (AI Psychological Analysis): Enter the other person's age, job, MBTI, KakaoTalk messages, and behavior patterns, and it analyzes them through attachment theory,

game theory, cognitive dissonance, and 28 other psychological theories. It tells you things like "the real reason they're leaving you on read" based on data.

2. Reunion Simulation: Set the reason for the breakup, who ended it first, and how long you've been apart, and based on the other person's personality

you can simulate a getting-back-together conversation. Practice before you actually reach out.

3. Conversation Practice: Rehearse conversations by scenario, like "I want to confess my feelings" or "Set up a date naturally" → the AI analyzes the conversation

and even generates a report.

4. Mirror Analysis: Set your own MBTI, and it reverse-analyzes you from the other person's perspective. You get to see "how the other person feels about you"

objectively.
