Bionic Reading Converter

Intensity

Convert any text into Bionic Reading format live — bolds the leading part of every word so your eyes fixate less, with rich-text copy that keeps the bold formatting when pasted elsewhere.

How it works

  1. Paste or type your text
  2. Pick an intensity — Light, Medium, or Strong
  3. The result updates live below; use "Copy formatted" to paste with bold intact, or "Copy plain text" for a plain version

Frequently asked questions

Can I paste the bolded text into an email or document and keep the formatting?

Yes — "Copy formatted (keeps bold)" copies rich text, so pasting into Gmail, Docs, or Word keeps the bold intact. Use "Copy plain text" for places that strip formatting anyway.

Can I adjust how much of each word gets bolded?

Yes, there are three intensity levels — Light, Medium, and Strong — controlling how much of each word's start is bolded.

Is any feature paid?

No. Everything here is free, with no account and no paid tier.

A paid Bionic Reading Pro user reported that EPUB conversion only bolded one word in five. Another popular tool needs a Convert button. Ours is fully free, updates live, and bolds every word without exception — we checked with an automated count to prove it.
