BeeLine Reader is fantastic for when I need to read massive walls of text online. I have it as a Chrome extension (it also comes as a mobile app, but I’ve never used it so I can’t really say much about it), and it’s probably the most useful thing I’ve ever installed!
Sometimes I need to read essays and articles for school and I know from the first glance that I won’t be able to focus long enough to do it. What the extension does is gets rid of every element on the page besides the article, makes the text bigger, and colors the text so it’s easier to follow from line to line (you can even change the colors it uses). It was originally designed to help people speed-read, but I’ve found it works wonders for me with my ADHD.
The only drawback I’ve found is that it doesn’t work for all websites and that sometimes I need to refresh it a few times before it can format the page properly.
This is basically what it looks like.
[I love Beeline Reader! I installed it on Chrome and it automatically reformats some sites (like Wikipedia and Huffington Post) and if there’s a PDF I can open it in my browser and apply the Reader to it. It’s great!]
