Human Benchmark is a web-based platform that offers a collection of simple yet challenging tests designed to measure and train different aspects of human cognition. The site includes games that evaluate skills such as reaction speed, short-term memory, visual processing, and attention span. Each test is short, interactive, and gives instant feedback with your score.
Users can see how they stack up against others by viewing percentile rankings and score distributions. While it's often used casually for fun, it also appeals to those interested in self-improvement, cognitive training, or tracking mental sharpness over time.
