Test your words-per-minute typing speed with live accuracy and error tracking.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Select test duration (15s, 30s, or 60s).
Start typing the highlighted words as quickly and accurately as possible.
Inspect your final WPM, accuracy percentage, error breakdown, and shareable performance tier.
WPM is calculated as (Total Correct Characters / 5) divided by time in minutes. Standard typing metrics standardize 1 word as 5 keystrokes.
The average global typing speed is approximately 40 WPM. Professional developers and typists typically score between 70 and 90 WPM, while competitive typists exceed 110+ WPM.
