Overview

ReadFast - Speed Reading with RSVP Technology

Dramatically improve your reading speed and comprehension using RSVP (Rapid Serial Visual Presentation) technology.

✨ How It Works

ReadFast works on any webpage with text content:

* Double-click any text to start speed reading
* Select text and right-click to read just that section
* No selection? The entire page will be displayed word-by-word
* From clipboard: Copy text from anywhere and press Ctrl+B to read content from outside the browser

⚡ Features

* Adjustable speed: Configure your reading pace via slider (up to 1000+ WPM)
* Customizable: Adjust colors, font size, vertical position, progress bar, and background transparency
* Full PDF support: Works seamlessly with PDF documents
* Keyboard shortcuts: Fully configurable via options menu

🎯 ORP Technology
ReadFast uses the Optimal Recognition Point (ORP) technique—displaying one word at a time with precise letter alignment so your eye doesn't need to move, allowing you to read at incredible speeds without sacrificing comprehension.
