MiroSync is a "mental self-care app" designed to help you reflect on and organize your thoughts and emotions through dialogue with an AI. "I have worries I can't share with anyone." "I feel a vague sense of unease in my heart." On nights like these, why not talk to the AI for a little while? Whether it is a daily worry, anxiety, or just a small event, simply speaking to the AI helps you notice the emotional shifts and thinking patterns occurring within you right now. The AI gently accepts your words and, through helpful questions and prompts, acts as a supportive guide to help you "understand yourself deeper." 【What you can do with MiroSync】 ◆ Always by your side, 24/7 Late at night or early in the morning, the AI is ready to listen gently whenever you want to talk. ◆ Organizing your thoughts Speaking helps clear your mind, allowing you to realize your honest feelings—"what I really wanted to do." ◆ A comforting space A private dialogue room just for you and the AI, where you will never be judged. ◆ See how your heart moves: Analysis In the "Analysis" tab, you can look back on a week of your dialogues. ・Emotion mix: the feeling you chose before each conversation, sorted into four categories—Positive, Calm, Uneasy, and Blue—and visualized for you. ・Emotion balance: positive rises above the center line, negative falls below. Your week of emotional sway, drawn as a waveform. ・Talk volume: a graph of when and how much you talked. Each day's feelings stack up in color. ・This week's report: every Monday morning, the AI reads through last week's conversations and leaves a comment just for you. 【Features of MiroSync】 ◆ Adopts a patented system We use a system patented in the U.S. and China, based on a unique method to balance the mind. (U.S. Patent: No. 10814094 / China Patent: No. ZL201780053422.7) ◆ Trusted by over 120,000 people The method forming the base of this system has a proven track record, having been taken by over 120,000 people. (As of October 2025) 【Would you like to get started?】 The gentle questions from the AI will serve as a guidepost to deeply understanding your heart. Why not start a new form of self-care that turns the noise in your mind into quiet peace? Note: This app is not intended for medical practice.
