About Braindex
What is Braindex?
Braindex is a free platform offering scientifically-grounded cognitive and personality assessments. We believe everyone deserves access to tools that help them understand how they think, what drives them, and where their strengths lie — without paywalls or hidden fees.
Our Assessments
🧠 IQ Assessment
30 carefully crafted questions spanning number sequences, logical reasoning, pattern recognition, matrix reasoning, and spatial reasoning. Difficulty-weighted scoring with time bonuses produces a reliable cognitive ability estimate.
🎭 Personality Assessment
50 real-world Likert-scale questions based on the Big Five (OCEAN) personality model. Your results are mapped to one of the 16 MBTI personality types with detailed reports covering strengths, growth areas, career paths, and famous people who share your type.
Our Approach
Our assessments draw from established psychometric research — the Big Five personality model and standardized cognitive testing frameworks. While our tests are designed for entertainment and self-reflection, they use real scoring methodologies to give you meaningful, actionable insights.
Free Forever
Every assessment on Braindex is completely free. No premium tiers, no locked results, no bait-and-switch. You take the test, you get your full results and detailed report — no strings attached.
