◈ OCEAN Assessor · Big-Five, grounded in IPIP

← Profiler Home

A descriptive Big-Five (OCEAN) trait estimate of the subject, grounded in the public-domain IPIP. Not a clinical diagnosis or a validated psychometric test.

Before you begin

This tool estimates where an anonymous subject sits on the five Big-Five / Five-Factor (OCEAN) personality dimensions — Openness, Conscientiousness, Extraversion, Agreeableness and Neuroticism. You answer the 50-item IPIP Big-Five questionnaire about the subject (rating how accurately each statement describes the subject, from Very Inaccurate to Very Accurate); a Claude Code session running in harness mode then reviews the scored profile, asks any clarifying questions, and produces a downloadable profile. It is a descriptive trait estimate — it does not diagnose, and it is not a validated psychometric assessment.

🛡️

Privacy by design. Input is limited to structured multiple-choice ratings about the subject — there is no free-text entry, so no names, addresses or other identifiers are collected. Nothing you enter is written to a database or logged; input is kept only for your live session and erased when you start a new assessment or it times out. The profile is generated in memory and downloaded to your device — never stored on the server.

🧭

Refer to the person as "the subject". The assessment is scoped to a single anonymous subject. Please describe only the subject, using neutral, non-identifying language.

Big-Five trait description only — this is not a clinical, diagnostic, or fitness-for-purpose assessment, and must not be used for employment, legal, or clinical decisions.

I understand this produces a descriptive personality-trait estimate of the subject, not a clinical diagnosis or a validated psychometric test. I confirm the input will be de-identified and I have any consent needed to describe the subject. I understand the personality items are drawn from the public-domain IPIP (ipip.ori.org), that results are an estimate, and that I remain responsible for how any output is used.

IPIP Big-Five questionnaire

Rate how accurately each of the 50 statements describes the subject, from Very Inaccurate to Very Accurate. Describe the subject as they generally are now, not as they wish to be. Rate each statement relative to other people of the same sex and roughly the same age as the subject.
