Browser extension
Read every site your way.
Your NeuroLens settings, on the websites you choose — news, blogs, Wikipedia, and the posts in your social feeds. Or send any article straight to the reader.
Coming soon to your browser's store
The extension is on its way to the Chrome Web Store, Edge Add-ons and Firefox Add-ons. The button to add it will be here the day it is listed.
What it does
Your settings, site by site
Switch it on for a site and its text takes your typeface, size, spacing, bold word starts, colours and reading mask. Menus and buttons stay as they were.
Read this page in NeuroLens
One click takes the article — or just the part you selected — into the reader, without the adverts and menus around it.
Social posts too
Posts on X, Bluesky, Facebook, Instagram, Threads, Reddit, LinkedIn and YouTube comments are treated as reading text.
No second sign-in
Open NeuroLens once in the same browser and your settings come across. Change one in the app and every site follows.
How to use it
- Add the extension from your browser's store, using the button above.
- Open NeuroLens in the same browser, signed in. Your settings come across on their own.
- On any site, click the NeuroLens icon in your toolbar and turn on Use my settings on. The browser asks once to allow that site.
- Pick what to change: Typeface and size, Spacing, Bold word starts, Colours and, if you use it, Reading mask. Turn the site off again and the page is exactly as it was.
- On an article, Read this page in NeuroLens opens it in the reader instead.
Privacy
The extension only touches the sites you switch on, and gives up its access when you switch them off. Your settings stay in that browser. Nothing about the pages you visit is sent anywhere, and it has no analytics. The full detail is in the privacy policy.
Questions
Which browsers? Chrome, Edge and Firefox on a computer. Brave, Vivaldi and other browsers built on Chrome install from the Chrome Web Store. Safari is not supported yet, and phone browsers do not take extensions like this one.
Does it cost anything? No. It is free, like NeuroLens.
A site looks wrong. Untick the part that is causing it in the popup, or switch that site off — it goes back to exactly how it was. Then tell us which site, so it can be fixed.
Dark sites and light colours. A site that is already dark keeps its own colours under a light palette such as Cream; turning photo-heavy dark sites light washes them out. The typeface, spacing, bold word starts and mask still apply.
