About this app

"I want to change, but my heart can't keep up."

"I suddenly lose track of how I feel because of work and relationships."

"Recently, I've been feeling depressed and can't sleep."

"I want to talk to someone about how I feel, but I'm a little scared to reveal my true feelings..."

Have you ever felt that way?

"mentment" makes your wish come true: what if you had your own mentor (advisor, understanding person) who gently supports you and supports you in taking your own steps?

◆ The story of a mysterious well that reflects your heart

This is the story of a mysterious well that reflects your heart.

Answer questions created with care by a team of experts at your own pace. Your words become the water that nourishes the plants, and beautiful flowers will bloom little by little in your heart.

As you continue to have fun talking to yourself like a game, you will discover true feelings that you have never noticed before. mentment provides a self-care experience that you can continue without any difficulty.

◆ Bringing psychology to your daily life

mentment was developed based on cognitive behavioral therapy, known in the field of psychology, and applies the idea of expressive writing (※1), which organizes your thoughts through writing.

We support you in developing the habit of metacognition, which allows you to objectively look at your own mind, just like looking in the mirror to groom yourself.

◆ Being there for you

Mentment will listen quietly to any story, 24 hours a day, 365 days a year. AI will select the best mission for you from texts created by experts. We value human warmth and empathy, and the peace of mind of being able to talk freely at any time.

The contents entered are strictly managed and cannot be seen by anyone other than you. In a safe space just for you, try to express your inner thoughts with peace of mind.

◆ A first aid kit that will be your "amulet" for difficult times

"I can't sleep because of sudden anxiety," "I want to relieve tension in front of people," "I'm feeling depressed and distressed" When you feel like that, open the "first aid kit." A special mission tailored to your mental state may help you to gently loosen up your stiff heart.

◆ Love your relationship with yourself more
In today's world, we get tired of comparing ourselves to others on social media. The most important thing is to "build a good relationship with yourself." mentment uses AI to gently encourage self-reflection (looking back at yourself), which is difficult to continue alone. The habit of reflecting on your mind as if you were dressing yourself in the mirror and listening to the voice of your heart will support you in cultivating a "safe base of the mind" that can withstand stress.
