About Human Benchmark
Human Benchmark is an open, free-to-use cognitive testing platform built to measure, track, and compare your brain's core abilities — from raw reaction speed to working memory and typing fluency — with scientific precision.
Our Mission
We believe every person deserves access to objective, scientifically grounded tools for understanding their own cognitive performance. Our mission is to provide simple, accurate, and accessible brain and reflex tests that allow anyone — students, athletes, gamers, researchers, or the simply curious — to establish baselines, track neuroplastic changes over time, and compare scores against global population percentiles.
Rather than gamifying intelligence into a single IQ number, Human Benchmark breaks cognition into measurable dimensions: visual reaction latency, auditory response speed, working memory capacity, sequential pattern recognition, verbal processing, typing motor fluency, and hand-eye coordination. Each test isolates a specific neural pathway, giving you a multidimensional cognitive profile.
Scientific Methodology
Each benchmark is engineered using high-precision hardware timestamps via the browser's performance.now() High Resolution Timer API. This provides sub-millisecond timing accuracy, minimizing input latency and operating system jitter that could compromise test reliability.
⚡ Sub-Millisecond Precision
Using performance.now() and requestAnimationFrame, we capture reaction timestamps with microsecond resolution, far exceeding the precision of traditional Date.now() calls.
📊 Statistical Percentiles
Your results are plotted against cumulative distribution functions derived from millions of completed tests, giving you precise percentile rankings rather than arbitrary "good" or "bad" labels.
🔄 Randomized Stimuli
All stimulus delays, sequence patterns, and word selections use cryptographically seeded pseudo-random number generators to prevent pattern anticipation and ensure test-retest validity.
🧪 Controlled Variables
Each test controls for confounding variables — inter-stimulus intervals are randomized to prevent rhythmic anticipation, and early-click detection penalizes premature responses.
Our Test Battery
Human Benchmark offers a comprehensive suite of cognitive assessments spanning multiple neural domains:
- →Reaction Time Tests — Visual and auditory reaction latency measurement in milliseconds
- →Memory Tests — Number Memory, Sequence Memory, Verbal Memory, and Chimp Test for working memory assessment
- →Typing Test — Words per minute (WPM), characters per minute (CPM), and live accuracy tracking
- →Aim Trainer — Click precision and target acquisition speed for hand-eye coordination
- →Visual & Color Tests — Color perception accuracy and visual processing speed
Privacy-First Architecture
All your test scores, historical data, personal bests, and dashboard charts are stored entirely in your browser's local storage (localStorage). We do not require registration, do not collect personally identifiable information, and never sell or share behavioral data with third parties.
You can export your complete benchmark telemetry as JSON for personal analysis, or clear all stored records at any time from your browser settings or the Dashboard.
Open & Accessible
Human Benchmark is completely free to use with no paywalls, premium tiers, or mandatory sign-ups. Our platform is accessible on any modern web browser across desktop, tablet, and mobile devices. We are committed to keeping cognitive testing democratized and universally available.
