About this app

Just writing can lighten your heart.
This is an emotional journal app where AI analyzes your emotions and delivers empathetic words and advice.
And the next morning—you'll receive a "reflection letter" from the AI.

Lumie is a self-care partner that visualizes your emotions simply by writing a journal, and helps you manage your emotions with the help of AI.
Try writing down "feelings you can't talk to anyone about" here.

◆ What you can do with Lumie
------------------
【AI analyzes and visualizes emotions】
When you write in your journal, the AI ​​scores four emotions (joy, sadness, anger, anxiety). You'll see emotional shifts you weren't aware of. You'll receive gentle, empathetic words without judgment, along with advice on shifting your perspective and taking small steps.

【One-tap mood check-in】 ← NEW
Record your current mood in 3 seconds with just one stamp. Even on busy days, your emotional record won't be interrupted. The intensity can be adjusted in three levels, and emotional data is accumulated even without writing.


[A "Reflection Letter" Delivered the Next Morning]
The morning after you write in your diary, the AI ​​delivers a letter that reflects your emotions. Receiving warm words first thing in the morning helps you start your new day positively.


[AI Counseling]
Based on your diary entries, you can chat with the AI. "I want someone to listen a little more," "I want to delve deeper into these feelings"—this is a safe space where you can have a conversation without hesitation, anytime.


[Photo Diary & Voice Input]
Add photos to your diary, or simply speak to convert your thoughts into text. Even on days when it's difficult to put your feelings into words, you can record them in a way that suits you.


[Easy Recording with Stamps]
On days when you can't find the words, simply choose a stamp that matches your current mood. You can intuitively record the flow of your emotions throughout the day in three time slots: morning, noon, and night.


[Dialogue with Your Past Self]
The AI ​​finds and suggests "days with similar emotions to your current one" from your past diary entries. Your past self will be your support now.

[Weekly Report & Statistics]
Review your emotional flow over the week with a graph. Includes correlation analysis between weather and emotions, and emotional patterns by day of the week. You'll gain insight into your own emotional rhythm.

[Kotodama Notebook]
Save words and important insights from AI as "Kotodama" (spiritual words). A personal talisman to look back on when you're feeling down.

[In-depth Analysis of 12 Emotions]
In addition to the four basic emotions, it detects eight more emotions: gratitude, loneliness, hope, regret, relief, impatience, accomplishment, and boredom. It gently points out cognitive distortions (such as "should" thinking) and displays a comparison of your growth with your past self.

[Weekly/Monthly AI Digest Letter]
A special letter that weaves together your weekly/monthly diary like a story. We will reflect on your emotional journey by quoting specific entries from your diary.

[Your Personal AI Counselor]
A counselor created just for you, based on all your past diary entries. It detects recurring themes and engages in dialogue using cognitive behavioral therapy (CBT) techniques.

[Emotional Pattern Prediction]
The AI ​​predicts your emotions for today based on the day of the week, weather, and recent trends. You'll receive a notification in the morning such as, "Today is a day when anxiety is likely to be high. Try to consciously make time to relax."
