This free online speed reading tool uses Rapid Serial Visual Presentation (RSVP) — a technique backed by decades of cognitive science research — to help you read faster without losing comprehension. Upload any PDF, paste any text, and start reading word-by-word at a fixed focal point. No account. No download. Works in your browser.
Read the passage below at your normal pace, then click Done to see your words per minute.
The passage above is 130 words.
When you read normally, your eyes move across each line in a series of jumps called saccades. Each jump takes 20–50 milliseconds, and your brain spends additional time planning the next one. RSVP eliminates this by presenting one word at a time at a fixed position — your eyes stay completely still, and words come to you.
This tool adds a focal point highlight — the key letter in each word is always at the exact same horizontal position. Your brain locks onto that point and never re-locates between words. The result is a reading experience that feels fast but controlled.
Upload any PDF — books, papers, reports. Text extracted locally. Nothing sent to a server. Chapter headings auto-detected.
Save your position as a short code. Paste it back next time to resume exactly where you left off — even on a different device.
Common words display faster. Long or rare words get more time. Sentence pauses scale with your reading speed.
Warm parchment background with Garamond font for a traditional reading feel. Three themes: Dark, Light, and Book.
The average adult reads at 200–250 WPM. College graduates average around 300 WPM. With RSVP training, most people reach 400–600 WPM within a few weeks while maintaining 80%+ comprehension. Start just above your comfortable speed and increase by 25–50 WPM every few sessions.
At moderate speeds (300–500 WPM), comprehension remains high — often equal to normal reading, because the fixed focal point reduces mind-wandering. Above 700 WPM, comprehension begins to drop on complex material.
Completely free, no account required. The tool runs entirely in your browser. Your PDFs are never uploaded anywhere — processed locally using PDF.js, Mozilla's open-source library.
Yes. Upload a PDF book and the tool auto-detects chapter headings, slows through them, then resumes speed. Save your position with a bookmark code after each session. A 90,000-word novel at 400 WPM takes about 3.75 hours — half the time of normal reading.
Start at 250–300 WPM — slightly above your natural reading speed. Keep sessions to 10–15 minutes. Most beginners feel confident at 400 WPM within 2–3 weeks of daily practice. Use the WPM test above to find your baseline first.
