Say goodbye to "not keeping up with my journal"
The ultimate simple self-analysis app
━━━━━━━━━━━━━━━━━━━━━━

"Good day," "Average," "Bad day"

Just choose one of these three options every day. It only takes 3 seconds.

Yet, AI will deeply analyze your values, strengths, and personality,
and scientifically discover "your own way to create a good day."

━━━ Why these three choices can change your life ━━━

Even with the same daily routine, some people have more "good days" than others.

This difference isn't due to "events."
It's due to differences in "cognitive filters" (how we see and perceive things).

For example, even if you work overtime, some people will feel that it was a "fulfilling day where I worked hard" while others will feel that it was a "tired, terrible day."

These differences in "filters" have a major impact on your daily happiness.

The 3-choice diary uses AI to continuously analyze your recording patterns. It helps you discover your own "rules for good days," such as: "I feel more fulfilled on days when I exercise in the morning," "I feel happier on days when I can make my own decisions," and "I'm more satisfied on days when I have deep connections with others."

By consciously acting in accordance with these rules,
you can intentionally create "good days" that previously depended on chance.

━━━ Grow in 4 Stages ━━━

[Stage 1] Build a Habit
Start with a 3-second 3-choice diary.
You can also write freely on days when you feel like it.
It's simple, so you can keep it up—this is the foundation for everything.

[Stage 2] Know Yourself
As your records accumulate, AI begins a deep self-analysis.
You'll realize, "This is who I am."

[Stage 3] Discover Patterns
Daily, weekly, and monthly reports will reveal the elements of a good day.
Your personalized data will be accumulated on the days that make you happiest.

[Stage 4] Intentionally change your behavior
The "Experiment" feature suggests actions based on the discovered patterns.
You can easily try it out as an "experiment" rather than a "thing you have to do."
