What changed, and why.

A browser extension for Chrome, Edge and Firefox that brings your reading settings to the websites you choose.

Most reading happens outside any one app. Switch it on for a site and its text takes your typeface, spacing, bold word starts, colours and reading mask; switch it off and the site is exactly as it was.

Posts on X, Bluesky, Facebook, Instagram, Threads, Reddit, LinkedIn and YouTube comments count as reading text too.

Read this page in NeuroLens sends any article, or the part you selected, straight to the reader.

Your settings come across from the app on their own. There is no second account and nothing about the pages you visit leaves your browser.

Sign in with Google — no password.

A password is one more thing to remember and one more thing to lose. Your books, marks and reading profile follow you between devices.

An account page that downloads everything you have, or erases it.

A help page covering every tool, and a support page that gathers the technical details for you.

Terms and an accessibility statement, both written to actually be read.

EPUB, Word, HTML, RTF and Markdown now open alongside PDF.

EPUB in particular reflows properly, so it suits this reader better than a PDF ever will.

An unfamiliar file is tried as text instead of refused.

Most things are prose under a name nobody listed.

One unreadable page no longer loses the whole book.

A page that will not parse is left blank and counted, and you are told how many.

Long PDFs count their pages while they load, so a slow file no longer looks like a broken one.

PDFs now open on older phones, which previously failed on every page.

Six highlighter colours.

One colour makes every mark mean the same thing. Six lets you sort as you read — the point, the doubt, the thing to look up.

Draw on the page: pen, marker, pencil and eraser.

Circling a paragraph says something a wash of colour cannot. A stylus draws straight away; your finger still scrolls.

Drawings follow the text when you change type size.

The page reflows, so ink is pinned to the line it was drawn on rather than to the screen.

Highlights carry their colour into the list, where you can change your mind.

PDF pages show reformatted text instead of a picture of the page.

The original page was being drawn on top of the very text extracted from it — which is the layout this reader exists to replace.

Any length of PDF opens; the old two-hundred-page limit is gone.

Words no longer break apart mid-word, and headings no longer run into the paragraph beneath them.
