Qualium is a new AI mental care diary that preserves indescribable emotions as "colors and shapes."
AI analyzes the invisible fluctuations of your heart.
By collecting them not just as text records but as beautiful "Qualia," you can deeply understand your own "rhythm" and "tendencies."
■ Key Features
・8 Emotion Analysis based on Psychological Models
The emotion analysis engine is designed based on psychologist Robert Plutchik's "Wheel of Emotions."
It defines 8 basic emotions like joy, trust, and fear, and their complex combinations, expressing complex heart patterns with scientifically backed beautiful gradients.
・AI Feedback incorporating CBT
Along with analysis results, AI delivers feedback that stays close to your emotions.
Incorporating perspectives from Cognitive Behavioral Therapy (CBT) and Acceptance and Commitment Therapy (ACT), it is designed to help you calmly review your emotions and notice thought habits.
・"Mental Trends" viewed through Positive/Negative
In addition to 8 emotions, it analyzes the balance of positive and negative emotions.
You can check your "mental trend" as objective data—whether your heart is looking up or needs rest.
・Emotions wear Colors and Shapes
The true feelings you spell out appear as a unique "Qualia" in the world.
The trajectory beautifully piling up on the calendar becomes your own collection, like art reflecting your heart.
・Once a Day, Record Only for Today
You can record only once a day.
No need to write a lot, nor take up much time. You can make the short moment of facing your heart a habit.
・Secure Design
Diary data is basically stored and managed within the user's device.
When linking accounts, backup data is encrypted and stored, so privacy is secure.
■ How to Use
1. Record Today's Mood
From the home screen, freely write down the day's events and emotions. (Input once a day)
2. Analysis by AI
Press the "Analyze" button, and AI analyzes the content. Qualia representing the day's emotions and feedback will arrive.
3. Reflection and Discovery
Check past Qualia and emotional transitions on the calendar or report screen. Grasp the tendencies of your heart.
