Real-time typing metric engine with character-level accuracy tracking and keystroke cadence visualization.
Validated System Telemetry
A zero-dependency browser-based typing diagnostics application. Accurately calculates net WPM, character error rate, and burst typing cadence in real time with zero input lag.
Eliminating keyboard event listener latency to support typists exceeding 140 WPM.
Handling international punctuation, backspaces, and burst word detection accurately.
Persisting historic user performance trends using localized offline storage.
