This tool estimates your Jungian personality type — a four-letter code across four dichotomies: Introversion–Extraversion, Sensing–Intuition, Thinking–Feeling and Judging–Perceiving. You answer 32 quick either/or questions on a five-point scale; your responses are scored instantly, in your browser, using a published, public-domain key. It is a descriptive approximation for reflection and self-understanding — not a clinical, diagnostic, or validated psychometric assessment.

This profiler does not use the proprietary MBTI questionnaire. It is an independent approximation built on the Open Extended Jungian Type Scales (OEJTS 1.2) by Eric Jorgenson — an open, public-domain instrument that yields a result comparable in format to Jungian type, licensed under CC BY-NC-SA 4.0.

Private by design. Everything runs locally in your browser — your answers are never sent to a server, stored, or logged. Your profile and the downloadable document are generated on your device. Close the tab and nothing remains.

I understand this produces a type approximation for reflection, not a clinical diagnosis, the official MBTI®, or a validated psychometric test. I understand the questions and scoring come from the public-domain OEJTS 1.2 (CC BY-NC-SA 4.0) and results are an estimate. I understand my answers are processed entirely in my browser and I remain responsible for how I use the output.
