I've used Type Faster and Sublime Text to achieve something like this but instead of books I've used articles/tutorials/documentation or articles in another language. In Type Faster I was creating new lessons with article I wanted to read. In Sublime Text I've used two panels - on left side I had article on right it was my typing space. While Type Faster shows you what word you have to type right now Sublime doesn't so I had to memorize as much words I wanted to type to avoid looking back and forth between panels. This is also useful when learning new language, if you are using Duolingo you most likely focus on speaking/reading/pronouncing words and not on writing so retyping articles in that language is very good method to memorize words. https://sourceforge.net/projects/typefaster/ https://sourceforge.net/projects/typefaster/
