3-Choice: AI Guided Journal

Mental Habits to Increase Your Good Days
Just 3 seconds a day. Simply choose between "Good day," "Okay," or "Bad day" — and watch your good days naturally multiply. Why? Because happiness isn't about what happens — it's about how you see it. 3-Choice Diary uses AI and psychology to refine your cognitive filter, helping you feel happier in your everyday life.
The Science Behind 3-Choice Diary
Designed to be effortlessly simple — even for those who never stick with habits. From your daily 3-choice entries, AI analyzes your values (10 types), strengths (24 categories), and personality (Big Five traits). Discover your personal formula for creating good days, backed by science. Track your cognitive growth through daily, weekly, and monthly reports.

With personalized action suggestions, you'll create more good days.
