Frequently asked questions

What is bionic reading?
Bionic reading is a way of styling text where the opening letters of each word are bolded and the rest is left light. The bold parts act as fixation points your eyes jump between, and your brain fills in the rest of the word, which can make scanning a block of text feel quicker and less tiring.
Does the bold formatting survive when I copy it?
Yes. The copy button puts the text on your clipboard as rich text, so the bolding pastes straight into a word processor, email or notes app. There is also an option to copy the underlying HTML if you want to drop it into a web page or a CMS that accepts markup.
Does bionic reading actually make you read faster?
Results vary from person to person. Some readers find the bolded word-starts help them skim and stay focused, while formal studies have been mixed on whether raw reading speed improves. The honest answer is to try it on your own text and keep using it only if it helps you.
Is my text sent to a server?
No. Everything runs locally in your browser. Your text is read and processed on your own device, nothing is uploaded, and nothing is logged or stored. Once the page has loaded, it keeps working even if you go offline.
