Bionic Reading Generator

Turn any text into a bionic-reading format that bolds the first part of each word, giving your eyes fixation points that can help you read faster and stay focused. Paste your text, choose the intensity, and copy the result. Everything runs in your browser.

What Is Bionic Reading and Does It Work?

Bionic reading is a formatting technique that bolds the first few letters of each word while leaving the rest in a regular weight. The idea is that your brain can recognise a word from its opening letters, so the bold "fixation points" let your eyes jump from word to word more efficiently, with less time spent decoding each one. Many readers — especially those who find dense text tiring, or who have ADHD or dyslexia — report that it helps them stay focused and read with less effort.

How the Fixation Works

For each word, this tool bolds a leading portion sized to the word's length. Short words get just one bold letter; longer words get more. The three intensity levels change how much of each word is emphasised:

What the Research Says

It's worth being honest: independent studies have produced mixed results on whether bionic reading actually increases reading speed or comprehension for the average reader, and some found no significant effect. What's clearer is that it's a low-cost, harmless aid that some people genuinely find helpful for focus and momentum. The best approach is to try it on your own material and judge by your own experience rather than treating it as a guaranteed speed boost.

It bolds the first part of each word so your eyes have clear fixation points. The theory is that the brain recognises a word from its opening letters, letting you move through text more efficiently. This tool applies that formatting to any text you paste.
Results are mixed. Some readers report better focus and momentum, while controlled studies have found little to no measurable speed gain on average. It's harmless to try, so the best test is your own experience on your own material.
Use "Copy (rich text)" to paste the bold formatting into Google Docs, Word, or email. Use "Copy HTML" to grab the underlying <b> markup for a web page or CMS.
Yes. Pick Low, Medium, or High intensity to bold roughly 40%, 55%, or 70% of each word. Shorter words always get at least one bold letter and never more than their length.
