There’s a number of companies researching ways to help speed read easily, without the normal practice it takes to learn to do it with normal printed pages and web articles. The idea is our brain’s can process the words much faster than we normally read. But we have to move our eyes down each line, and most people mentally say the sounds of the word. These two things slow us down a lot. So companies like one called “Spritz” has done quite a bit of research to make speed reading easy. They have an API available to integrate their tech in your webapp, mobile app, or even website.
Someone has taken their technology (or something similar—not sure) and created a Book of Mormon speed reading webapp.
