You might check out BeeLine Reader (I am the creator). [1] It's fairly popular in the ADHD community because it enhances visual focus while you're reading. Some people are able to read for 2x-10x as long with BeeLine versus without. I'm always happy to help out HNers with a free code for our browser plugin, just shoot me an email (contact in profile).
Is this the same beeline from 10 years ago? I sort of remember installing it back in middle school and really loving it and helping my ability to read walls of text. I never knew it got popular within the ADHD community or that it was still around.
Another reader helper I liked was the one that flashed words in place but that seemed more like a speed read hack rather than actually comprehending what you read, never used it seriously like BeeLine
Yep, the same one. You probably heard of us from our Show HN, [1] which I later found out was the 9th-most-popular Show HN, by upvote count. It really gave us a boost, and led to a flurry of media coverage!
We still have our browser plugins for web [2] and PDF, [3] but are now also integrated into education platforms, [4] and even some news websites. [5]
I've been bootstrapping it (and raising a family) so growth has not been as meteoric as some other startups, but it's been consistently up-and-to-the-right!
If there's ever a platform you'd like to see us work with, just let us know and we'll get on it.
