I made a similar thing at wordflashreader.vercel.app, cool to see a different implementation. https://github.com/SpyC0der77/wordflash

I built this because I have ADHD and reading anything longer than a tweet felt impossible. I'd re-read the same paragraph 5 times and still not absorb it.

Also, the focal point (red character) is meant to stay as the same spot as the words progress
