For: ages 16 and up
A free 60-question personality test that sorts you into one of sixteen four-letter types and gives you a written profile. It borrows its type format from Myers-Briggs but says it is built on the Big Five, and the reliability figures it shows come from the company itself. Treat it as a conversation-starter about how you see yourself, not a verdict or a diagnosis. The free result sits next to paid reports and an AI mentor, and the page keeps offering to unlock more, so you can stop once you have your type.
