What is Bionic Reading Converter?
The Bionic Reading Converter emphasises the first half of every word so the eye lands on a strong anchor before the rest of the word. Paste any text and choose HTML or Markdown output. Word order, punctuation, and spacing stay unchanged, and the markup is ready to paste into a blog, newsletter, or reading app.
How does Bionic Reading Converter work?
Each run of letters is matched and split in half, with the first half wrapped in b tags for HTML or double asterisks for Markdown. The split rounds up, so a six-letter word bolds three letters and a seven-letter word bolds four.
Punctuation is never placed inside the emphasis, and words joined by apostrophes or hyphens are treated as a single run. The output is text markup rather than styled text, so it can be pasted into a CMS or editor that accepts HTML or Markdown.

- Bolds the first half of each word, rounded up
- HTML output with b tags
- Markdown output with double asterisks
- Keeps apostrophes and hyphens inside the word
- Leaves punctuation and spacing untouched

Common Use Cases
Adding a reading aid to a blog post
Generate HTML you can paste into a CMS so readers can switch to an emphasised version of an article.
Preparing a Markdown draft
Produce Markdown with bold word starts for a newsletter or documentation page that renders Markdown.
Testing readability with readers
Create two versions of the same passage to compare how a focus aid changes reading speed.
Building study material

Pro Tips
- 1
HTML output uses b tags, which most CMS editors accept but some strip on save.
- 2
Markdown output uses double asterisks, so it works anywhere Markdown is rendered.
- 3
Words with apostrophes keep the punctuation outside the bold section, so don't becomes don bold plus the rest.
- 4
Short words are heavily emphasised because half of a four-letter word is two letters.
- 5
Keep the source text so you can regenerate the markup if you change your publishing platform.
Frequently Asked Questions
What is bionic reading?
Bionic reading is a formatting technique that bolds the first part of each word so the eye has a fixed anchor. It does not change the words themselves, only how the text is displayed.
How much of each word gets bolded?
The first half, rounded up. A five-letter word bolds three letters and a four-letter word bolds two, so short words look proportionally heavier.
Does the converter change my text?
No. Only markup is added around the opening letters. The words, their order, and the punctuation between them stay exactly as written.
Which output format should I use?
Choose HTML for a CMS field that accepts tags, and Markdown for a newsletter, README, or docs site that renders asterisks as bold.
Will the emphasis survive a copy into Word or Google Docs?
HTML pasted into a word processor usually becomes real bold text. Markdown pasted as plain text keeps the asterisks, so render it through a Markdown editor first.
