A growing library of science-based psychology tests, designed for thoughtful self-reflection, not diagnosis.
The principles behind every test we build.
Every test cites its source instrument. We build on validated scales where they exist, and we're transparent when they don't.
Clear language, minimal clutter, predictable flows. Our tests are designed to be accessible to the widest possible audience.
No accounts, no tracking pixels, no data sold. Your results stay in your browser unless you choose to email them to yourself.
No flattery, no fear. We tell you what the data says, acknowledge uncertainty, and point you to professional help when it matters.
Wherever a validated clinical instrument exists, we build on it. We don't invent our own scales when the field already has good ones. For topics where no validated instrument exists, we're upfront that the framework is our own synthesis, and we describe our method on the test page itself.
We are not a medical provider. Our tests are screening and self-reflection tools, not clinical assessments. If a result worries you, please speak with a qualified professional.
If you're in crisis, you can find a helpline in your country.
