Why RSVP speed reading works
The full story →One word at a time
RSVP shows each word in one fixed spot, so the words come to you instead of your eyes chasing them.
How it works →Less eye movement
Normal reading is full of tiny jumps and pauses. Hold your gaze still and the focal point does the work.
The science →Find your pace
Start near 300 wpm and nudge it higher. Comprehension catches up with a little practice.
Reading tips →Private & free
Your text never leaves your device — everything runs in your browser.
Privacy & FAQ →Take it anywhere
