The Free Online RSVP Speed Reader
Zeek uses Rapid Serial Visual Presentation (RSVP) to display words one at a time at a fixed point on your screen. No eye movement. No distractions. Just focused reading at speeds from 100 to 900+ words per minute.
What Is RSVP Reading?
RSVP stands for Rapid Serial Visual Presentation — a technique developed in cognitive psychology research where text is shown one word (or chunk) at a time in the same location. Traditional reading requires your eyes to move across each line, jump back to the start of the next, and occasionally regress to re-read missed words. RSVP eliminates all of that movement.
By presenting each word in a fixed position, RSVP reduces the time spent on saccades (eye jumps between words) and suppresses subvocalization (the habit of silently pronouncing each word). The result is faster reading with sustained comprehension.
Built for Dyslexia, ADHD & Visual Processing
Zeek was designed with accessibility at its core. Here's how RSVP helps different readers:
Dyslexia Support
Single-word display eliminates line-tracking confusion and reduces letter transposition. The large, high-contrast word stage minimizes visual crowding — a key challenge for dyslexic readers.
ADHD Focus
The fixed-point presentation keeps attention locked to one word at a time. There's nothing else on screen to distract — no surrounding paragraphs, no sidebar content. The continuous motion maintains engagement naturally.
Visual Processing
Zeek highlights the Optimal Recognition Point (ORP) — the letter position where your eye naturally fixates for fastest word recognition. This reduces cognitive load per word.
Features
Adjustable Speed
Read at 100 to 1,000+ WPM. Adjust in real time with the speed dial while reading.
ORP Highlighting
Each word's optimal recognition point is highlighted in red, guiding your eye to the ideal fixation letter.
Camera OCR Scanner
Point your camera at any printed text — books, documents, whiteboards — and Zeek extracts the words for RSVP reading.
Keyboard Shortcuts
Space to play/pause, arrow keys to skip words, plus/minus to adjust speed. Full hands-free control.
Mobile Gestures
Swipe left/right to skip words on touch devices. Portrait mode shows a word queue for context.
Progress Seeking
Drag the progress bar to jump to any position in your text. The word counter tracks exactly where you are.

Frequently Asked Questions
What is an RSVP speed reader?
RSVP (Rapid Serial Visual Presentation) is a reading technique that displays words one at a time in a fixed position on screen. Instead of moving your eyes across lines of text, each word appears in the same spot, eliminating eye movement overhead and reducing subvocalization. This can increase reading speed by 2-3x while maintaining comprehension.
How does Zeek help with dyslexia and ADHD?
Zeek reduces visual clutter by showing only one word at a time, which helps readers with dyslexia avoid letter-swapping and line-skipping. For ADHD, the fixed-focus presentation minimizes distractions and maintains engagement. The adjustable speed lets each reader find their comfortable pace, and the ORP highlighting guides the eye to the ideal fixation point on each word.
Is Zeek free to use?
Yes, Zeek is completely free. There are no accounts, subscriptions, or paywalls. Simply paste your text or use the camera scanner and start reading immediately in your browser.
Can I scan printed text with Zeek?
Yes. Zeek includes a built-in camera scanner powered by Tesseract.js OCR. Point your device camera at any printed text — books, documents, whiteboards — capture a photo, and Zeek will extract the text for RSVP reading.
What reading speed should I start with?
Most people read at 200-250 words per minute (WPM) naturally. Start Zeek at 250 WPM and gradually increase. Experienced RSVP readers often reach 500-800 WPM. The speed dial lets you adjust in real time while reading.
Does Zeek work on mobile?
Yes. Zeek is fully responsive and supports touch gestures (swipe to skip words) and portrait reading mode with a word queue. The camera OCR scanner also works on mobile devices.
Is my text stored or sent anywhere?
No. All processing happens locally in your browser. Your text never leaves your device — there are no servers, no analytics on your content, and no data collection.
