FastReader ⚡📖

FastReader is a modern, privacy-focused speed reading application that leverages the Rapid Serial Visual Presentation (RSVP) method. By displaying words one by one at a fixed focal point, it eliminates the need for eye movement (saccades), allowing you to read faster and with less fatigue.

🚀 The Science of Speed Reading

The reading technique used in FastReader is based on cognitive psychology research from the 1970s (Potter, Forster) known as RSVP.

It was popularized commercially by Spritz in 2012, which introduced the concept of the "Red Optimal Recognition Point" (ORP). This aligns each word so your eye stays perfectly still, allowing the brain to process text instantly. While traditional reading caps out around 200-300 WPM for most, RSVP users can often comfortably reach 500+ WPM.

✨ Features

• ⚡ RSVP Engine: Precision timer with WPM control (100-1000+ WPM).
• 🎯 Optimal Recognition Point: Red-highlighted focus letter for efficient processing.
• 📚 Local File Support: Drag & drop EPUB and TXT files.
• 🔒 Privacy First: 100% offline. Files are processed locally in your browser and never uploaded to any server.
• 🎨 Beautiful Themes: Choose from Dark, Light, Vibrant, or Soft palettes.
• 📈 Stats & Analytics: Track words read, time spent, and average speed.
• 🏋️ Training Mode: "Auto-Accelerate" feature to gradually increase speed while you read.
• 💾 Auto-Resume: Remembers exactly where you left off in every book.
• 📱 PWA Support: Installable on iPhone, Android, and Desktop.

🛠️ Technology Stack

• Framework: React + TypeScript (Vite)
• State: React Hooks + Context
• Styling: Vanilla CSS Variables (No external UI frameworks)
• Storage: IndexedDB (via idb) for large file storage
• Parsing: epubjs for ebook structure
