Bionic output

The human brain is an extraordinary pattern-matching machine. When you read, your eyes don't glide smoothly across the page — they leap from point to point in rapid movements called saccades. Your brain predicts the rest of each word based on just a few key letters.

Bionic Reading works with this natural process. By bolding the first letters of each word, it gives your eye an anchor point to land on. Your brain recognises the word instantly and moves on, reducing the cognitive effort required to process each line.

Research suggests that this technique can increase reading speed by 20 to 30 percent while maintaining or improving comprehension. It is particularly effective for people with dyslexia, ADHD, or those reading in a second language.

Try pasting your own text above and adjusting the fixation level to find what works best for you.

How it works

  1. 1 Paste any text into the input — articles, books, emails, or study notes.
  2. 2 The converter bolds the first few letters of every word, creating a visual anchor point.
  3. 3 Your eye lands on the bold segment; your brain predicts the remainder, speeding up recognition.
  4. 4 Adjust the fixation level, font, and size to find the setting that feels most natural to you.
  5. 5 Copy the HTML to use in a CMS or email, or copy plain text for other editors.
