What is bionic reading?

Bionic reading is a way of formatting text that highlights the beginning of each word. The first few letters are bold and the rest of the word stays regular, so every word gets a small visual anchor, often called a fixation point. The idea is that your eyes jump from one bold anchor to the next, and your brain fills in the rest of each word from experience.

Skilled readers don’t look at every letter anyway. The eyes make quick jumps (saccades) and pause briefly on parts of words, and bold fixation points are meant to make those pauses easier to land on.

How to use the bionic reading converter

1. Add your text. Type or paste it into the text box, or click Sample text to see an example first.
2. Set the fixation strength. Choose a level from 1 to 5. Level 1 bolds about a fifth of each word, and level 5 bolds about 70%.
3. Choose the saccade. Bold the start of Every word, Every 2nd word or Every 3rd word.
4. Style it for reading. Pick a Font, Font size, Line height and Reading theme, and use Fade the rest if you want the non-bold letters lighter.
5. Read it. The preview updates as you type. Click Reading view to read in full screen.
6. Copy or download. Click Copy formatted to paste with bold into Docs, Word or Gmail, or use Copy as HTML, Copy as Markdown or Download .html.

Features

Five fixation strength levels

The Fixation strength setting goes from 1 (a light touch) to 5 (most of each word in bold). Short words always get at least one bold letter, and longer words get more.

Saccade: every word, every 2nd or every 3rd

Saccade controls how often a word gets a bold start. Every word gives the strongest guide. Every 2nd and Every 3rd look closer to normal text, which some readers find calmer for long sessions.

Fade the rest

Move the Fade the rest slider to make the regular part of each word lighter, so the bold anchors stand out even more. Leave it at Off for normal contrast.

Fonts, size and line height

Choose a Sans, Serif or Mono font, set the Font size from 14 to 28 pixels, and adjust the Line height for more breathing room between lines.

Light, sepia and dark themes

The Reading theme setting switches the preview and the reading view between Light, Sepia and Dark.

Reading view

Reading view opens your converted text in a full-screen, distraction-free layout with comfortable line lengths. Use A− and A+ to change the text size, switch themes from the top bar, and press Esc or Close (Esc) to go back.

Copy into Google Docs, Word and Gmail

Copy formatted copies the text with real bold formatting, so the fixation points stay bold when you paste into Google Docs, Microsoft Word, Gmail, Outlook or most other rich-text editors. Paragraphs and line breaks come with it.

Copy as HTML or Markdown

Copy as HTML gives you clean code with bold tags and paragraph tags, and Copy as Markdown wraps the bold part of each word in double asterisks, ready for Notion, Obsidian, GitHub or any Markdown app.

Download as an HTML file

Download .html saves a standalone web page with your text, font, size and theme, so you can read it offline in any browser.

Smart word handling

• Punctuation before and after a word stays regular, so quotes, commas and periods aren’t bold.
• Words with apostrophes and hyphens are handled properly, like “don’t” and “well-known”.
• Numbers, emoji, web addresses and email addresses are left as they are.
• Accented letters and scripts like Hindi (Devanagari) are split by whole characters, so letters and conjuncts aren’t broken in half.

Does bionic reading really help you read faster?

It depends on the reader. Research on bold fixation points is mixed, and controlled studies haven’t shown a consistent boost in reading speed or comprehension for most people. Many readers still say it helps them stay focused, skim faster or get through long text with less effort. Others find it distracting.

The best way to find out is to try it with your own text. Read a page at different fixation strengths, compare it with the normal version, and keep whatever feels better. It’s a personal preference, not a magic trick.

Who might find it helpful

• Students reviewing notes, textbook chapters and study guides
• Professionals skimming long emails, reports and documents
• Readers who lose their place in dense paragraphs or long lines
• Some readers with ADHD or dyslexia say they find it helpful, though it isn’t a treatment and won’t suit everyone

Tips for comfortable reading

• Start at fixation strength 2 or 3. Higher levels can feel heavy in long text.
• Try Every 2nd word if the page looks too busy.
• Pair a larger Font size with a Line height of 1.7 or more.
• Use Sepia or Dark in the reading view for long sessions.
