Science-based Big Five analysis

Not a fortune-telling app.
This app is a science-based personality test built on the Big Five (BIG5) personality model, one of the most widely used frameworks in psychological research.

Instead of labeling you as “good” or “bad,” this app helps you understand your personality tendencies objectively through five core traits.


【What is the Big Five (BIG5)?】
The Big Five model describes personality using the following five traits:

・Openness
・Conscientiousness
・Extraversion
・Agreeableness
・Neuroticism

These traits are not judgments or diagnoses.
They simply represent different tendencies in how people think, feel, and behave.

This app visualizes your results using clear charts and explanations, making it easy to understand your personal profile.
