The ORP (red letter) stays fixed while words flow past, eliminating eye movement and dramatically increasing reading speed.

Quick Start

# Install dependencies
npm install

# Start development server
npm run dev

# Build for production
npm run build

Open http://localhost:5173 and load a file to start reading. Try the built-in samples or load your own ebooks and documents.

How It Works

RSVP displays words one at a time at a fixed focal point. The Optimal Recognition Point (ORP) - the letter your eye naturally focuses on - is highlighted and centered, eliminating the need for eye movement across the page.

ORP positioning by word length:

• 1-2 letters: 1st letter
• 3-6 letters: 2nd letter
• 7-9 letters: 3rd letter
• 10+ letters: 4th letter

Smart timing adjustments:

• Punctuation (. , ! ?) adds 50% pause
• Long words (10+ chars) add 20% pause
• Names/proper nouns add 30% pause

Tech Stack

• Framework: SvelteKit with Svelte 5 runes
• Language: TypeScript
• EPUB Parsing: epub.js
• PDF Parsing: pdf.js (pdfjs-dist)
• Storage: localStorage for settings and progress
• Styling: CSS (no framework)
