Measure real-time Words Per Minute (WPM), CPM, accuracy score, and character typing rhythm.
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 15s, 30s, or 60s challenge duration.
Type the highlighted text passage in the input field as fast and accurately as possible.
View your final Words Per Minute (WPM), Accuracy percentage, and total characters typed.
Standard WPM is calculated as (Total Correct Characters / 5) divided by time in minutes.
The average typing speed is around 40 WPM. Professional typists and software engineers typically type between 65 and 90+ WPM.
