Low vision, migraines, light sensitivity
Low vision & light sensitivity
Boost contrast, invert glaring white pages, and scale font size up to 200% without breaking a site's layout.
ADHD & attention differences
ADHD & focus challenges
Bionic Reading and generous line height give your eyes a clearer path through text, reducing the drift that long paragraphs invite.

English as a second language
ESL & second-language readers
Slow down Read Aloud, hear correct pronunciation, and follow along visually with Bionic Reading to reinforce word recognition.
General eye strain & fatigue
Everyone, at the end of a long day

What readers say
Loved by readers who needed something better
"Bionic Reading plus OpenDyslexic changed how my son does his homework. He reads news articles on his own now instead of asking me to read them to him."
"I have chronic migraines and bright websites used to end my workday early. The color filter and invert mode let me keep reading without the glare."
"Read Aloud is the feature I didn't know I needed. I listen to long documentation pages while I code and it just works, on every site."

FAQ
Frequently asked questions
What is ReadEase?
ReadEase is a free Chrome extension that makes any website easier to read. It adds Bionic Reading, Read Aloud text-to-speech, dyslexia-friendly fonts, adjustable spacing, and color filters on top of the page you are already viewing, without changing the underlying content.
Is ReadEase free to use?
Yes. Every feature described on this site, including Bionic Reading, Read Aloud, custom fonts, spacing controls, and color filters, is free with no sign-up or account required.
Does ReadEase work on every website?
ReadEase applies its reading enhancements to standard web pages you visit in Chrome. It cannot modify Chrome's internal pages (such as chrome://extensions) or the Chrome Web Store, which browser extensions are restricted from accessing.
Does ReadEase collect or sell my data?
No. ReadEase stores your reading preferences locally using Chrome's built-in storage and does not collect browsing history, page content, or personal data for sale or advertising. See the Privacy Policy for full details.
What is Bionic Reading and how does it help?
Bionic Reading bolds the leading letters of each word, creating fixation points that guide your eyes through text. Your brain completes the rest of each word from memory, which can reduce fixation time and help some readers process text faster.
Can I use ReadEase with a screen reader or other accessibility tools?
ReadEase is designed to complement, not replace, assistive technology such as screen readers. Because it uses semantic style changes, it generally coexists well with other accessibility extensions, though we recommend testing your specific combination of tools.
Which voices are available for Read Aloud?
Read Aloud uses the text-to-speech voices already installed on your operating system and exposed to Chrome, so the exact list depends on your device. You can choose any available voice and set playback speed from 0.75x to 2x.
How do I install ReadEase?
Install ReadEase from the Chrome Web Store, pin it to your toolbar, and click the icon on any page to open the settings panel. Toggle features on or off instantly; changes apply immediately without reloading the page.
