TypeSpeed nga Libor Benes (Dr. B)

⌨️ TypeSpeed puts a professional typing speed test directly into your Firefox sidebar — always one click away, never interrupting your workflow.

Press the green Start button, position your hands, and start typing when you are ready. The counter is waiting for you to start typing. The 60-second countdown begins the moment your first character lands. No second button to press. No distraction.

⏱️ THE TEST
• An animated SVG ring counts down 60 seconds in real time. Live WPM, word count, and character count update every second while you type.
• At 10 seconds remaining, the ring and countdown flash bold red — a peripheral-vision alert that lets you keep your eyes on your text.
• When time is up, your result appears immediately: WPM, words typed, characters typed, accuracy estimate, and a plain-language performance grade.

Note: The timer begins on your first keystroke — not on a button press. Press START, settle your hands on the keyboard, and go. No lost seconds fumbling between mouse and keys.

📊 WPM — HOW IT IS CALCULATED
TypeSpeed measures the text that actually made it into the box — your effective output after corrections — not raw keystrokes. This gives a fair, meaningful WPM: the number that reflects how much useful text you produce per minute, which is what employers, courses, and typing trainers actually care about.

📐MEASUREMENT METHODOLOGY
WPM = words typed / 60 seconds x 60. At test end this simplifies to your raw word count.

🏆 PERFORMANCE GRADES
🟢 80+ WPM — Excellent, professional-level speed
🟡 60–79 WPM — Great, above average
🟠 40–59 WPM — Good, solid everyday pace
🔵 20–39 WPM — Developing — keep practising
⚪ 0–19 WPM — Keep going — every session counts

Average adult: ~40 WPM. Professional typists: 65–75 WPM. Competitive typists: 100+ WPM.

💾 EXPORT AND SAVE RESULTS
• Every completed test is saved locally — WPM, word and character counts, accuracy estimate, start and end timestamps, and the full text you typed.
• Each result can be saved to its own timestamped plain-text file, for example:

TypeSpeed_2026_05_17_at_16_01_58.txt


Firefox's native Save As dialog opens so you choose where the file goes. Firefox remembers your chosen folder, so subsequent saves default to the same location automatically — whether that is Downloads, Documents, or anywhere else.

🎯 Target Audience:
• Students learning touch typing or preparing for timed writing assessments.
• Professionals looking to improve their typing speed and productivity.
• Writers and developers who spend significant time typing and want to track progress.
• CS educators teaching keyboarding skills or incorporating typing benchmarks into curriculum.
• Job seekers preparing for typing tests as part of application processes.
• Anyone curious about their typing speed and looking for a private, no-tracking solution.
