What does FermatMind do?
FermatMind offers free online personality tests and career interest exploration tools, including MBTI-style personality types, Big Five, Enneagram and Holland Code (RIASEC). The Holland Code tool offers 60- and 140-question options, returning a six-interest profile and three-letter code. Explanatory results and career resources help users reflect on their preferences and explore learning directions, including how AI may affect work and skills. The tools support self-reflection; they are not clinical diagnoses, hiring assessments or guarantees of career fit. Created by Fuwei Liu, the sole developer. Current tests and results are free. Paid single-test services at USD 0.99 and USD 1.99 are planned but have not launched.
