About Human Benchmark
Human Benchmark is a free, browser-based platform dedicated to measuring and understanding the full spectrum of human cognitive performance. From the speed of a visual reflex to the depth of short-term working memory, our tests are carefully designed to give you accurate, meaningful scores you can actually learn from — not just numbers on a screen.
The platform was born from a simple question: how do you know how fast your brain really is?Anecdotal comparisons don't cut it. Self-reported estimates are wildly inaccurate. The only way to get a true picture of your cognitive abilities is to measure them — rigorously, repeatably, and in a way that allows you to compare against a real global dataset.
Our Mission
Our mission is threefold: to make high-quality cognitive benchmarking accessible to everyone for free; to build the world's largest, most diverse dataset of human cognitive performance; and to educate people about the neuroscience behind the abilities they're testing. We believe that understanding your brain is the first step to improving it.
Whether you're a competitive gamer looking to sharpen your reflexes, a student studying how working memory affects learning, an athlete monitoring your mental performance across a season, or simply someone curious about how your mind compares to the global average — Human Benchmark provides the tools and the context to make that comparison meaningful.
The Tests: What We Measure and Why
Every test on the platform corresponds to a well-established domain of cognitive or motor science. Here's a brief breakdown of what each measurement actually tells you about your brain:
⚡ Reaction Time
Measures the time between a visual stimulus appearing and your physical response. This is dominated by neural conduction velocity and attentional readiness. The global median hovers around 273 ms — top performers consistently achieve sub-200 ms.
🧩 Sequence Memory
Tests the visuospatial sketchpad component of Baddeley's Working Memory Model. Your brain must encode, retain, and replay an increasingly long ordered sequence — a direct measure of short-term memory capacity and procedural recall.
🎯 Aim Trainer
Quantifies motor precision and speed simultaneously using Fitts's Law — the foundational model for predicting the time required to rapidly move to a target area. Your score reflects both fine motor control and visuomotor integration.
🔢 Number Memory
Tests your digit span — one of the oldest and most replicated measures in cognitive psychology. The average adult can reliably hold 7 ± 2 items in working memory. This test finds your personal ceiling.
💬 Verbal Memory
Measures semantic memory and recognition. Unlike recall tasks, recognition memory shows how much your brain implicitly stores beyond what you can consciously retrieve — a core component of language and long-term learning.
🐒 Chimp Test
Adapted from Kyoto University research showing young chimpanzees outperform adult humans at photographic number recall. Tests eidetic spatial memory under time pressure — an area where human cognition trades raw speed for language and abstract reasoning.
👁 Visual Memory
Evaluates spatial pattern recognition and the capacity of visual short-term memory (VSTM). Research shows most people can hold 3–5 objects in VSTM at once. This test progressively challenges that limit.
⌨️ Typing Speed
Measures words per minute (WPM) and accuracy on a standardized passage. Beyond productivity, typing speed is a well-validated proxy for working memory utilization and motor sequence automation.
How Scores and Percentiles Work
Every score on Human Benchmark is placed on a percentile curve built from real test data collected globally. When you see that your reaction time puts you in the 80th percentile, it means your score is faster than 80% of all recorded attempts across all devices and locations. The data pool is global, diverse, and continuously growing.
We make no adjustments for age, device type, or geography in the global percentile — your raw score is compared to the raw population. This keeps the benchmark honest. However, we do note that hardware latency (monitor refresh rate, mouse response time, internet connection for networked tests) can influence certain scores, which is why we publish our methodology openly.
Scores are designed to be repeatable and comparable over time. If you create a free account, you can track your personal best scores across sessions and watch your performance improve. Users who practice consistently show measurable improvement — particularly in reaction time, aim accuracy, and typing speed.
Meet the Creator
Vishv Kamani
Founder & Developer
Human Benchmark was designed, built, and is maintained entirely by Vishv Kamani — a developer passionate about the intersection of web technology and cognitive science. The vision was to create a platform that takes the rigour of psychometric research and makes it freely accessible to anyone with a browser, without registration walls or paywalls.
The platform's scope continues to expand. New cognitive tests and features are regularly added based on user feedback, published research, and emerging areas of cognitive science. If you have ideas, feedback, or want to connect, Vishv is always happy to hear from the community.
The Science Library
Beyond the tests themselves, Human Benchmark features a growing library of long-form science articles that explore the research underlying each cognitive domain. These articles cover everything from the neuroscience of reaction time to the evolutionary origins of working memory, drawing on peer-reviewed research and written to be accessible to a general audience.
The science library is an ongoing project. Articles are continually added, updated, and refined to reflect current research. If you notice a factual inaccuracy or have a topic you'd like us to cover, please don't hesitate to reach out.

The tests and content on Human Benchmark are designed for educational and entertainment purposes only. They are not clinical assessments and should not be used for medical diagnosis, clinical decision-making, or as a substitute for professional neuropsychological evaluation. Scores on this platform do not diagnose or rule out any cognitive condition.
