merotalk: LINE Compatibility

merotalk analyzes your LINE chat history to reveal your communication compatibility.

【Features】

▼ Compatibility Score
Import your LINE chat history to get a compatibility score based on 4 axes: volume, emotional warmth, rhythm, and depth. Visualize your communication patterns.

▼ Personality Type
Discover your personality type and your partner's based on chat tendencies, with compatibility insights and communication tips.

▼ AI Summary
AI-powered monthly conversation summaries that help you look back on how your relationship has evolved.

▼ AI Consultation (Consultation Room)
Chat with "Meromaru," an AI character who offers relationship and communication advice based on your actual chat history, inside a dedicated chat-style consultation room.

▼ Persona Chat
AI learns your chat partner's tone and personality so you can chat with them and simulate how they might respond.

▼ What-If Chat (NEW)
Rewrite a message you once sent and see how the conversation could have gone differently — AI predicts your partner's alternate replies.

▼ Detailed Data Analysis (Premium)
Unlock love expression analysis, compatibility insights, time-of-day trends, and more.
