About Big 5 Test

Personality tests are more useful when you can recognize an everyday habit in the result. We built Big 5 Test for that small moment of recognition: why a busy gathering leaves you looking for a quiet room, why an unfinished plan keeps borrowing your attention, or why your calendar fills with favors before you check it.

The site combines a public-domain IPIP Big Five questionnaire with original 16-type and Enneagram questionnaires. Each is a different way to reflect on your responses. We explain the source and limitations on our methodology page.

A report, not a subscription

You can answer the questions without an account. A full report costs USD 2.99 for one completed test. We show that price before you start, and you can read a sample report before deciding. There is no recurring plan or automatic renewal.

The report includes dimension scores, explanations, practical experiments, and a character card. The score calculations and report assembly are deterministic. We do not send each person's answers to an image or language-model service to create their result.

A little character

Our geometric illustrations are original, AI-assisted artwork created for this project. The nicknames and quotes add humor, but they are not scientific categories. Several different profiles can share a side character.

We do not reuse MBTI or 16Personalities character assets. Big 5 Test is an independent project and has no affiliation with those brands.

Corrections and questions

We do not claim that our original questionnaires are independently validated. We also do not invent customer counts, success rates, or professional endorsements. If a question or explanation seems wrong, please tell us what you noticed at contact@big5test.net.
