SpeedReader shows a book's text one word at a time, always in the same spot on the screen, at the pace you choose. Your eyes stop scanning lines and your attention stays on meaning. This is RSVP (rapid serial visual presentation) — a way to read faster with less fatigue. READING • 100 to 900 words per minute, 1–4 words at a time • Space to pause and resume; left/right arrows step one word, up/down arrows change speed (with a keyboard on Mac and iPad) • Slightly longer pauses at periods and commas, so the text reads naturally • Clean text: page numbers and repeated running headers (including chapter titles) are removed, hyphenated words are joined • Optional highlight of the optimal recognition point (ORP) • Word typeface of your choice: sans-serif, serif or monospaced BOOKS • Import PDF, EPUB, FB2 or plain-text (.txt) files from your device or cloud storage through the system file browser • Scanned PDFs or PDFs with a broken text layer: recognize the text on your device (OCR) once and read it • Pick the pages (or chapters, in an EPUB) to read first and skip contents and front matter • The library remembers where you stopped in every book • Named bookmarks return you to the exact word • Table of contents from the book itself or from detected chapter headings • Full-text search: find a word or phrase and start reading right there • For PDFs, "Open this place in the PDF" shows the original page with the current sentence highlighted QUOTES • One tap saves the current sentence with the book and page number • Add author, publisher and year and copy a ready citation: "quote" — Author. Title. Publisher, year, p. N • Quotes are grouped by edition; copy them all at once PRIVACY • No sign-up, analytics or ads. Books, bookmarks and quotes stay on your device. Works on iPhone, iPad and Mac, in English and Russian. Made by Vlad Sitnikov. Inspired by Anton Bulanov and his book "The Nature of Cunning" (Природа хитрости).
