Psychological self-assessment
Know your mind.
Honestly measured.
Take the same personality and wellbeing questionnaires used in published research — the Big Five, PHQ-9, GAD-7, PCL-5 and more — administered in full, scored by their official rules, and explained without hype. For adults 18+. Never a diagnosis.

Position in scale range — every result page tells you exactly what a score can and cannot say.
Why trust this
Most online tests invent their questions. We print our licences.
Real instruments only
Public-domain and freely licensed questionnaires, with provenance and citation printed on every test page.
No AI in your numbers
Scores are computed by each instrument's published rules in plain code. The AI only writes the optional narrative — and says so.
We refuse fake tests
No knock-off MCMI. No “take the PCL-R online”. When a test can't legitimately exist on the web, we teach you why instead.
Curious about the tests we won't host? Read why the MCMI and PCL-R can't legitimately be taken online.
How it works
Answer honestly
Every instrument is administered in full — real items, original response scales, nothing abridged. Your progress saves on your device as you go.
Scored by the book
Your numbers come from each questionnaire's published scoring rules, computed in plain code. No AI touches your scores, ever.
Explained with care
If you want it, specialist AI agents turn your computed scores into a plain-English narrative — clearly labelled, never a diagnosis.
