Words are displayed one at a time with a highlighted focal letter, training your eyes to stay centered and eliminating subvocalization — the habit that slows most readers down.

Features: - RSVP reader with a color-highlighted focal letter for each word - Adjustable speed from 50 to 1,000 words per minute - Two play modes: Play/Pause or Press to Play (hold to read, release to stop) - Chapter navigation for multi-chapter EPUBs - Import documents: EPUB, PDF, TXT, and Markdown files - Read web articles by pasting a URL - 7 monospace font choices including JetBrains Mono, Fira Code, and Courier Prime - Adjustable font size - Reading position saved automatically — pick up where you left off - Pure black dark theme designed for OLED screens - No account required. All data stays on your device.
