Psychological self-assessment

Know your mind.
Honestly measured.

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

Step 1 of 3

Answer honestly

Every instrument is administered in full — real items, original response scales, nothing abridged. Your progress saves on your device as you go.

Step 2 of 3

Scored by the book

Your numbers come from each questionnaire's published scoring rules, computed in plain code. No AI touches your scores, ever.

Step 3 of 3

Explained with care

If you want it, specialist AI agents turn your computed scores into a plain-English narrative — clearly labelled, never a diagnosis.

The instruments

Seven ways to see yourself

See all tests

Big Five (IPIP-50)

50 items · ~10 min

IPIP-NEO-120

Free

Johnson's 120-item public-domain inventory measuring the Five Factor Model in depth: five broad domains plus thirty narrow facets (e.g. Anxiety, Assertiveness, Altruism, Self-Discipline). The most detailed personality profile on this platform.

120 items · ~20 min

PHQ-9

Free

A widely used 9-item screening measure for symptoms of depression over the past two weeks. A screener, not a diagnosis.

9 items · ~3 min

GAD-7

Free

A widely used 7-item screening measure for symptoms of anxiety over the past two weeks. A screener, not a diagnosis.

7 items · ~2 min

PCL-5

Free

A 20-item screening measure of post-traumatic stress symptoms over the past month, developed by the U.S. National Center for PTSD. Please note: the questions ask about reactions to a very stressful experience, which some people find difficult — you can stop at any time. A screener, not a diagnosis.

SAPAS

Free

An 8-question screen for personality difficulties. A positive screen does not mean you have a personality disorder — it only means a fuller assessment with a professional could be informative. Around 1 in 7 people screen positive.

8 items · ~1 min

SD3

Free

A 27-item research measure of three 'dark' but normal-range personality traits: Machiavellianism, narcissism, and trait psychopathy. Everyone scores somewhere on these dimensions — elevations describe interpersonal-style tendencies, never a diagnosis.
