This platform was created with one simple goal: to help you understand how you think, decide, and grow.
Not through complicated theories. Not through overwhelming reports.
But through clear, engaging experiences that help you reflect on yourself in a simple and practical way.
When you understand how your mind works, small things start to change.
You make decisions with more confidence.
You recognize your strengths faster.
You begin to notice patterns in how you react, think, and solve problems.
You grow intentionally — not accidentally.
That's what this platform is here to support.
Our tests are created to be:
No pressure. No labels. No judgment.
Just clear insights that help you see yourself more clearly.
Some people take one test out of curiosity.
Others enjoy coming back regularly to challenge themselves and discover more.
Every result adds another layer to your personal profile.
Over time, those small insights build something powerful: clarity.
This isn't about proving anything to anyone.
It's about learning something new about yourself.
One test at a time.
One insight at a time.
One small improvement at a time.
Common questions about Marble IQ, your Mindprint, and how subscriptions work.
Marble IQ is a cognitive profiling platform that builds your personal Mindprint — a living map of how your brain actually works across 8 dimensions. Unlike personality quizzes, every test on Marble has correct answers. Your results are based on actual cognitive performance, not self-report.
Most IQ tests give you a single number. Marble gives you a profile. We measure 8 distinct cognitive dimensions — visual intelligence, logical reasoning, pattern recognition, processing speed, strategic thinking, creative intelligence, and more — because your brain isn't one-dimensional and neither should your results be. Each test is designed to be genuinely difficult, visually engaging, and impossible to fake.
Our tests are built on established principles from cognitive psychology and psychometric research — the same frameworks used in professional IQ and aptitude assessments. They are not clinical diagnostic tools, but they are designed to produce meaningful, reliable measurements of real cognitive abilities. The patterns they measure are well-documented in the scientific literature.
You can take any test on Marble without an account. To see your full results — including your detailed cognitive profile, personalized AI insights, and Mindprint scores — you need to create a profile and subscribe. Subscription also unlocks daily and weekly challenges, which are the fastest way to build and track your cognitive profile over time.
Subscribers get full results for every test, access to their complete Mindprint across all 8 dimensions, personalised AI-generated insight reports, and daily and weekly cognitive challenges. Challenges are designed to test different cognitive dimensions each day and week, so your Mindprint grows more accurate and detailed the more consistently you engage.
Challenges are shorter cognitive tests released on a daily and weekly schedule. Each one is designed around a specific cognitive dimension, so regular participation gives you a richer, more detailed Mindprint than single tests alone. They're also how most subscribers discover which cognitive dimensions they're strongest — and most surprising — in.
Yes. You can retake any test at any time. Your first attempt typically produces the most accurate baseline — familiarity with the format can improve scores on retakes. We recommend waiting at least a few weeks between attempts for a meaningful comparison.
A single test measures one type of cognitive performance on one type of task. It's a data point, not a verdict. If your result surprised you, the best response is to take more tests — your full Mindprint across multiple dimensions will give you a much more complete picture. Cognitive profiles are most meaningful when built from multiple measurements over time.
Yes, you can cancel at any time. There are no contracts or commitments. If you cancel, your subscription remains active until the end of your current billing period — after that, your access to full results, Mindprint data, and challenges will revert to the free tier. Your profile and test history are saved, so if you resubscribe later, everything picks up where you left off.
We accept all major credit and debit cards. All payments are processed securely through Stripe — your card details are never stored on our servers. Subscriptions renew automatically at the end of each billing cycle. You'll receive an email reminder before renewal, and you can manage or cancel your subscription at any time from your account settings.
