What is speed reading?
Speed reading is a set of techniques that let you read more words per minute while keeping comprehension high. The main brake on speed is not thinking, but two habits: your eyes moving across the lines, and subvocalization (saying words in your head). ElioBook tackles both directly.
Fewer eye movements
By showing words at a fixed point, your eyes stay still and stop jumping from word to word.
Less subvocalization
A steady pace stops you from silently pronouncing each word, which naturally speeds up reading.
Sharper focus
One word at a time means fewer distractions, more sustained attention, and less needless re-reading.
How RSVP reading works
RSVP stands for Rapid Serial Visual Presentation: words flash one by one, always in the same spot on screen. Your brain assembles them without your eyes having to move.

Frequently asked questions
What is RSVP reading?
RSVP (Rapid Serial Visual Presentation) displays words one at a time in the same spot on the screen. Your eyes no longer move across lines, which removes the time lost to eye movements and lets you read faster.
Does speed reading hurt comprehension?
At moderate speeds, RSVP keeps comprehension high because it reduces subvocalization and re-reading. Past a certain threshold, comprehension drops, so ElioBook lets you adjust the speed to find your own balance.
How fast can I read with ElioBook?
An average reader reads around 200 to 250 words per minute. With ElioBook the speed is adjustable from 100 to 1,000 words per minute: many users comfortably read at 400 wpm and above on texts that lend themselves to it.

Yes. ElioBook imports your EPUB files and splits them into chapters. You can also paste any text or article directly to read it in speed mode.
