I've seen this on an adhd (I'm not diagnosed) page on twitter. While the reactions are mixed, I do find reading this way to be easier. It's like my eyes have a guide on where they should focus. Sometimes when I'm trying to read, my brain is just not cooperating and the whole page looks like one jumbled mess.
The major problem I see here is the company itself seems to be very
greedy, charging up to 500 bucks if you wanna use their "AI" on your content/website. They are already
threatening lawsuits to anyone making their own (as if making the first few letters of each word bold is groundbreaking). And a few have pointed out that there is no study behind this. The whole thing seems to be easily replicable.
Personally I'd like to have this option on those days where I just can't process any words on the page.
