Your eyes are
slowing you down.
Drop in an EPUB, a PDF, a Kindle book or the paper you keep meaning to read. ReadKinetic plays it back one word at a time, in a single fixed spot, so your eyes stop hunting across the page and you actually get through it.
The file is opened inside your browser and never uploaded — which is also why all of it keeps working with no internet connection at all.
Coming from Spreeder or SwiftRead? Here is how this compares.
Since you opened this page
At 250 WPM conventional vs. 500 WPM RSVP. The gap compounds with every page.
Nearly 30% of your reading time is spent on pure eye movement — not comprehension.
Traditional reading involves saccades — rapid, involuntary eye jumps between fixation points. Your eye lands on a word, processes it for ~230 milliseconds, then lurches to the next. Between those fixations, your visual system is effectively blind.
Add the return sweep to the start of each new line, and regression — the reflex to drift backwards over something you already read — and a real share of your reading hour is not reading at all. RSVP removes all three, and does nothing whatever about the voice in your head, which is a limit no technique can lift.
Saccadic movement
Your eyes jump between fixation points. Each jump is ~30 ms of blindness, compounded thousands of times per page.
Regression
The eye backtracks to re-read already-processed text, often automatically. Rises sharply under fatigue.
Return sweeps
At each line end, the eye must locate the beginning of the next — a precise movement that often requires correction.
Subvocalization
Internal articulation caps reading speed at speaking speed. RSVP above 350 WPM effectively dissolves this ceiling.
Library
Thirty-nine file types
EPUB, PDF, Kindle (MOBI, AZW3), FictionBook, Word, OpenDocument, PowerPoint, LaTeX and more. See them all — including what it refuses, and why.
Progress
Picks up where you stopped
Your place, your speed and your typeface are kept per book. Close a 900-page textbook mid-chapter and it reopens exactly there, weeks later — and a twelve-character code moves your place to another device, with no account and no server.
Privacy
Nothing is ever uploaded
Files are parsed in your browser and stay on your device. No account, no server. Turn off your wifi and import a book — it still works.
Languages
Reads Japanese, Chinese, Thai
Scripts without spaces between words break most readers entirely. This one segments them properly and counts Japanese in 文字/分. How.
Engine
The pace reads the text
It eases off before a hard word and carries a slower pace through a dense passage, worked out from the book itself. Sixteen lit scenes, bionic mode, focus guides, sleep timer.
Offline
Install, then disconnect
A PWA that works with no internet after first load. Add to your home screen on any device.

Speed Reading with ADHD: Why One Word at a Time Can Help
