RSVP reading shows one word at a time at a fixed point so your eyes stop moving and your brain just reads. Try it below on a sample passage, or paste your own text. No signup, no download.
This demo caps at 400 WPM. The full reader unlocks up to 1000 WPM, file uploads, and URL import.
Open Full ReaderRSVP stands for rapid serial visual presentation: text delivered word by word, in rapid succession, at a single visual point on the screen. It is a display method, not a speed reading trick in the vague sense. The name describes exactly what is happening, one word presented, then the next, in a fixed spot, at a pace you control.
Normal reading is not actually a smooth left-to-right scan. Your eyes move in short jumps called saccades, landing briefly on a word or cluster of words, pausing to focus (a fixation), then jumping again. Some of that jumping is even backward, re-reading a phrase your brain did not fully catch the first time. All of that movement takes time, and none of it is spent on comprehension itself. It is spent on finding where to look next.
RSVP removes the searching. Because the next word always appears in the same place, your eyes can stay still while your brain does the actual work of reading. Read Fast also aligns each word to its Optimal Recognition Point, or ORP, a specific letter, usually just left of center, held at that same fixed spot every time. Eye-tracking research on reading has consistently found this is roughly where the eye already prefers to land when recognizing a word, so anchoring it there removes one more small source of friction.
| Method | Eye movement | Typical comprehension |
|---|---|---|
| Normal reading | Saccades and fixations across each line, with some backward re-reading | High, this is the baseline the brain is built for |
| Skimming | Fast, wide eye movement, skipping large sections of text | Low, useful for scanning but not for retaining detail |
| RSVP reading | None, the eye stays fixed while words move through it | Good at moderate speeds, declines at high speeds per the research below |
Marc Brysbaert's 2019 meta-analysis of reading rate research puts the average adult silent reading rate for non-fiction at approximately 238 words per minute. That is the baseline most readers start from before trying RSVP.
With RSVP, most people can comfortably reach 400 to 700 WPM once the fixed-point format feels natural, well above the normal reading baseline. But that range is not free of tradeoffs. Research on eye movement and reading comprehension, including Rayner and colleagues' 2016 review, has found that comprehension measurably declines as presentation speed climbs, especially above roughly 400 to 500 WPM and especially with unfamiliar or dense material. Faster is not automatically better if you are not actually retaining what you read.
The honest takeaway: RSVP raises your ceiling by removing eye movement as a bottleneck, but comprehension still has its own limits. Find the speed where you can genuinely follow the material, not just the number that feels most impressive.
RSVP as a research concept goes back to reading and psycholinguistics studies from well before any consumer product used it. Spritz, a startup that launched publicly around 2014, is the version most people searching for "spritz reading" actually remember: it packaged RSVP with its own branded version of a fixed recognition point and briefly appeared in several third-party keyboard and reading apps. Spritz itself is no longer a widely available consumer product today.
The underlying technique it popularized, one word at a time, aligned to a fixed focal letter, was never exclusive to Spritz. It is the same core idea this reader uses, without any Spritz branding or licensing behind it.
The demo above is a taste of RSVP reading. Two next steps if you want more:
Open the full RSVP reader
The full reader adds file uploads (PDF, EPUB, TXT), URL import, and progress tracking across sessions, on top of the same ORP-aligned display used in the demo above.
Measure your baseline first
Not sure what WPM to start RSVP at? Take the free reading speed test to get your real, comprehension-checked WPM first, then use that as your starting point on the slider above.
Read the research behind it
See the science of speed reading for a deeper look at fixations, saccades, and what the evidence actually supports.
RSVP stands for rapid serial visual presentation. It is a way of displaying text one word at a time in a single fixed position, instead of letting your eyes scan across a full line or page. Because the words come to you rather than you searching for the next one, RSVP removes the eye movement that normal reading requires, which is why it can support much faster reading speeds.
It can, especially at higher speeds. Research on eye movement and reading, including work by Rayner and colleagues (2016), has found that comprehension tends to decline as presentation speed increases, particularly above roughly 400 to 500 words per minute, and particularly for dense or unfamiliar material. RSVP is not a way to bypass comprehension limits entirely. It is a way to remove one specific bottleneck, eye movement, so you can find your own honest ceiling rather than being slowed down by something unrelated to understanding.
That is the Optimal Recognition Point, or ORP: a specific letter in each word, usually just left of center, that stays fixed at the same spot on screen every time. Studies on eye fixations during reading show your eye naturally lands near this point when recognizing a word. Highlighting it and holding it steady means your eye never has to search for where to look next, which is most of what makes RSVP feel faster than normal reading.
Yes. The demo on this page is free with no signup, and reads at up to 400 WPM. The full reader at /reader is also free at that same speed, plus paste and URL import. A paid tier exists for speeds up to 1000 WPM, file uploads (PDF, EPUB, TXT), and unlimited daily use, but none of that is required to try RSVP reading.
Spritz was an early company that popularized RSVP reading around 2014, built around its own version of ORP-style word alignment. Spritz itself is no longer widely available as a consumer product. The underlying technique, RSVP with a fixed focal point, is not proprietary and predates Spritz by decades in reading research. This reader uses the same core idea: one word at a time, aligned to a fixed recognition point, without Spritz's specific branding or licensing.
Start around 250 to 300 WPM, close to the average adult silent reading rate, and increase gradually. Jumping straight to 500 or 600 WPM before your eyes and brain adjust to the fixed-point format usually hurts comprehension more than it helps speed. The slider in the demo above defaults to 300 WPM for exactly this reason.
