BeeLine founder here; interested to see this. My first reaction was that the "before" text in the before/after demonstration is both thin and grey.

It is well known that text that is too thin and too light-colored is not great to read. The text modification shown here makes certain letters easier to read, but it appears this is partially because the rest of the text is specifically difficult to read. The background of the page very light grey, it looks like, which would magnify this effect even more.

I wonder what this would look like with a not-too-thin-font that is black or near-black. I also wonder what it looks like on a full-width paragraph, as the sibling commenter mentioned.

Regardless, it's always nice to see innovation in this space!

Since you work in this field, I'd be interested if you would really qualify this as innovation. I have posted already in several places in this thread about the fact that Bionic Reader is at least 3 years old already. Someone else also dug up the patent application: The rules to make the text bold in Bionic Reader in its simplest form (i.e. ignoring things like setting Saccade manually) apparently is just a very very simple if-else that takes 3 lines of code.

Also, have you patented BeeLine as well?

I wonder how messy it would look to combine the two? BeeLine really works, especially in cases where the designer has disregarded the need for reasonable column widths. I feel this works too, but as with BeeLine the visual appearance is a bit jarring at first.
