Saccadic eye jumps & regressions
The reading platform to boost your reading focus.
Stop moving your eyes and start processing ideas. Visus is a fast, open-source platform that uses Rapid Serial Visual Presentation (RSVP) to show you text one word at a time. This simple change cuts out the constant eye jumping and the inner voice that slows most readers down.
From long EPUB books to complex work PDFs, our reader adapts to your pace. You can train your brain to hit 1000+ words per minute while keeping your focus sharp and your comprehension high.
Read on your terms, at your speed.
Visus is designed to make reading effortless. Whether you're catching up on technical docs or diving into a novel, we've built the tools to help you stay focused.
Built for your focus.
Reading shouldn't be a chore. Switch between fonts and themes designed to reduce eye strain and keep you immersed in the text for hours.
Your data, your device.

Frequently asked questions
The science behind faster reading
Visus is more than a document viewer. It is a cognitive training platform engineered to help you process text faster while improving retention.
Breaking the subvocalization habit
Most readers internally "hear" words, capping speed at ~250 WPM. Visus trains your brain to process word shapes as pure concepts, bypassing the inner voice to shatter your speed limits.Learn about speed reading
Eliminating saccades and eye fatigue
Traditional reading requires mechanical eye jumps (saccades) that cause fatigue. Our RSVP method presents text at a fixed point, keeping your eyes still and your focus sharp.
Privacy-first document processing
Visus operates entirely in your browser. Whether using our EPUB reader or loading PDFs, your files never leave your device. 100% private, 100% offline.
