Stasis: The Quiet Way to Read Fast. One word. One point of stillness. Stasis is a reading sanctuary — a minimalist RSVP speed reader that streams your books through a single focal point. Your eyes stay still. Your mind moves fast. The Science of Stillness Traditional reading is quietly exhausting. Your eyes leap from word to word, stumble, circle back — most of your energy spent on the journey, not the meaning. Stasis removes the journey. Each word arrives exactly where your eyes already rest, and your brain processes language at its natural, unhurried speed. Focus, Refined — The RSVP engine: fluid delivery from 50 to 1,000 WPM — Paced comprehension: micro-pauses that breathe with the punctuation, so speed never costs understanding — An interface that vanishes: no scrolling, no page-turns, no noise — Ambient sound: rain, fireplace, birdsong — a room tone for your reading — OLED-deep themes and serif typography, tuned for long sessions For Every Kind of Reader Restless attention, wandering focus, or dyslexia — the portal meets you where you are. Choose from curated reading fonts including OpenDyslexic, Atkinson Hyperlegible, and Lexend. Your Library, Accelerated Import EPUBs and PDFs or paste any text. Chapters, table of contents, and progress are preserved — your "to-read" pile quietly becomes a "finished" list. A Habit, Not a Chore Streaks that forgive. Monthly reading reports that celebrate what you did — never guilt for what you didn't. Watch your pace grow, then share your month as a single beautiful card. Everywhere You Read A free account backs up your library and syncs your progress across devices. Close the app on the train, reopen it on the couch — the next word is waiting. Read faster. Stay longer. That's Stasis.
