Read answersWhat is HumanSpec?
HumanSpec is a free browser-based test lab for reaction time, memory, typing, and other everyday performance signals. It is designed for quick practice and self-comparison, not for diagnosis.
Do I need an account?
No. You can run the public tests without signing up. Results are shown in the browser, so save a note or screenshot if you want to keep a personal record.
What is a good reaction time?
Many people score around 200–300 milliseconds on a simple visual reaction task. Display latency, input hardware, anticipation, fatigue, and practice all affect the result.
How can I improve my reaction time?
Use the same setup, reduce distractions, and practice in short sessions. Consistency and a stable baseline matter more than one unusually fast attempt.
What is a good typing speed?
A typical adult typing speed is often around 40–60 words per minute, but the useful comparison is your own speed at a similar accuracy level.
Is typing accuracy more important than WPM?
A fast score with many errors can be less useful than a slightly slower, accurate score. Read speed and accuracy together.
What does a number memory test measure?
It measures how many digits you can briefly hold and reproduce. It is a narrow working-memory task, not a complete measure of memory or intelligence.
How can I improve visual memory?
Use a consistent strategy, group items into smaller patterns, and practice in short sessions. Familiarity with the task can improve consistency.
What should I compare: my best score or my average?
For a useful baseline, compare a small range or median across valid attempts. A personal best is motivating, but it is more sensitive to luck and conditions.
Why can two websites give different scores?
Tests may use different instructions, timing methods, stimuli, scoring rules, and hardware assumptions. Scores are most useful within the same test and setup.
How accurate is a browser test?
A browser can provide a useful personal signal, but it is not laboratory equipment. Display refresh, browser load, input hardware, and local timing behavior influence the result.
Does HumanSpec diagnose ADHD, cognitive decline, or other conditions?
No. HumanSpec is for education and entertainment. A browser score cannot diagnose a medical, neurological, psychological, IQ, or employment-related condition.
Are my test results private?
Public tests do not require an account. Avoid entering personal information into a test, and review the site privacy policy for details about analytics and optional contact forms.
Can I use a score for hiring or school decisions?
No. A short browser task is not a fair or validated basis for high-stakes decisions about another person.
