RSVP Reader — flash any text, word by word
Paste anything, pick a speed from 150 to 800 WPM, and the reader flashes it one word at a time with the focal letter marked — the same mechanic every speed-reading app demos. The honest part comes at the end: we ask what it said. Free, in your browser, nothing stored.
Sample loaded — 102 words. Paste your own text to replace it.
Every formula, benchmark source, and limitation is documented on the methodology page. Nothing you type here is stored or sent anywhere — the math runs in your browser.
Questions, answered honestly
What is RSVP reading?
RSVP stands for Rapid Serial Visual Presentation: words are flashed one at a time in a fixed position, so your eyes never move across a line. Because eye movements and regressions are eliminated, words can be presented far faster than most people normally read — which is why RSVP demos feel so dramatic.
Does RSVP actually make you read faster?
It makes words arrive faster — that isn't the same thing. Research on reading (Rayner and colleagues, 2016) puts the practical comprehension ceiling around 400–500 WPM. RSVP is genuinely useful as a training drill for reducing subvocalization and regressions, but flashing text at 700 WPM doesn't mean you understood it at 700 WPM. That's why this tool's finish screen points you at a comprehension test instead of congratulating you.
What speed should I set?
Start near your real reading speed — the adult average is about 238 WPM (Brysbaert, 2019) — and raise it in steps of 25–50. The useful zone is slightly above comfortable: fast enough that your inner voice can't keep up, slow enough that meaning still lands. If you don't know your speed, take the free 2-minute test first.
Is this tool free? Do you store my text?
Free, no signup. Your pasted text never leaves the browser — the flashing happens entirely on your device and nothing is uploaded or stored. Analytics record only that the tool was used, never what you pasted.
How is this different from ReadingFast's training?
This is the free 90% — a flasher. The training app wraps the same mechanics in a closed loop: comprehension checked every session, speed that adjusts to your scores, and a plan that progresses over weeks. Flashing feels fast; the loop is what makes speed stick. Published training results run roughly 30–60% improvement over about six weeks — typical, not guaranteed.
