What is bionic reading?

Switch it on, change the strength, and see the difference. This is what you get on every page.
The eye does not read letter by letter. It jumps, pauses, and fills the gaps from memory. Bionic reading works with that habit. It anchors the start of each word so your gaze has somewhere to land, then lets your mind carry the rest of the sentence.

What Bionic Reader does
Works on any website
Bionic Reader applies bionic reading to any page with text: articles, newsletters, documentation, email, and drafts written in a web editor. There is no per-site setup.
Three reading strengths
Choose Light, Balanced, or Bold to control how much of each word is bolded. Balanced suits most reading, and Bold helps with dense text or tired eyes.
Private by design
Bionic Reader runs entirely on your device and requests no network access, so no page you read is ever sent anywhere. There is no account and no tracking.
On and off in one tap
Toggle bionic reading from the toolbar button or with Alt+B. Switching it off restores the page exactly as it was, and the extension never alters the sites you visit.
Add Bionic Reader free
Pick your browser. No account, no card.
- Nothing leaves your device
- Works on any site with text
- Switch it off and the page is unchanged

The same reading mode, over your own manuscript
Bionic Reader is free and stays free. The mode it brings to the web is built into NovelOS Studio as well, where it runs over the chapter you are drafting, so you can reread your own writing with fresh eyes and catch what you had stopped seeing.
Plan it, write it, revise it in one place.
NovelOS Studio keeps your plot, characters, world and manuscript in one project on your own device. Write by keyboard or by voice, bring in the draft you already have with Smart Import, work through your revision with margin notes, and see the book as pages in Book Preview before you export it. It costs $45 once, for Windows, macOS and your phone.
