This bionic reading converter reformats ordinary text by bolding the first part of each word. Those bold openings act as fixation points your eyes can latch onto, so you spend less time scanning and more time reading. Paste anything in, pick how strong you want the effect, and copy the result.
How bionic reading works
When you read, your eyes do not glide smoothly across a line — they jump between fixation points and your brain fills in the gaps. Bionic-style formatting front-loads each word with a bold cue, giving your eyes an obvious place to land. For many readers that means less back-tracking and a steadier reading rhythm.
It is especially popular with people who find dense blocks of text hard to focus on, including some readers with ADHD or dyslexia. It is a reading aid, not a cure — the right setting is whatever feels most comfortable to you.
Choosing an intensity
- Low bolds about the first 40% of each word — a subtle nudge.
- Medium bolds about half — the most common, balanced choice.
- High bolds up to about two-thirds — a strong cue for skim-reading.
Try the same paragraph at each level and keep whichever helps you most. There is no single “correct” amount; readability is personal.
Keep the formatting when you paste
Reading on this page is fine, but you will often want the converted text somewhere else — a study doc, an email, or your notes. Copy formatted text preserves the bold styling as rich text, so it survives a paste into Google Docs, Microsoft Word, Outlook and most rich editors. If you paste into a plain-text-only box, the bold is dropped and you get the original words back.
Private by design
Your text is converted right here in your browser. Nothing is uploaded, stored, or logged — so it is safe to run articles, work documents or personal notes through it.
