Four kinds of reading help, in one place, remembered per site.
Why it exists
The reading-help extensions each do one thing. A dyslexia-friendly font here,
a colour overlay there, a line focus somewhere else — and someone who needs one
of them usually needs two or three. Today that means installing three extensions
that argue with each other over the same page, or giving up.
The font is the only part of this that is well served. Everything beside it —
overlays, spacing, a line focus — either does not exist above a thousand
installs or is bundled into a product that wants an account first.
What it does
Typeface, including OpenDyslexic bundled with the
extension rather than assumed to be installed on your computer.
Text size, line height, letter, word and paragraph spacing.
Wider spacing helps more people than a different typeface does, and it
never changes how the page is laid out.
A colour overlay in the tints used for Irlen-style
filters, applied as a layer rather than by rewriting the page's colours,
so text keeps its contrast.
Remembered per site. A page that needed help still has it
tomorrow, and a site you never adjusted follows your usual settings even
after you change them.
The reading ruler — the one paid feature
A band that follows your pointer and quiets everything else, measured in
lines rather than pixels so it stays the right size when you have also made the
text bigger. One purchase, no subscription.
What it does not do
It asks for no permission to read your browsing. By
default it changes only the page you point it at. Applying automatically
on every site is a checkbox that asks, and can be revoked from the same
checkbox.
Local files and the PDF viewer are left alone. There is
no site there to remember a decision against.
A site that draws its text as images cannot be restyled by anything.
