WHAT IS BIONIC READING?

Bionic reading bolds the first part of each word so your eyes can lock onto word shapes and keep a steady reading pace. Paste an article to convert it — handy for skimming long text.

How to use?

  1. Paste any text into the left input — supports Chinese/English mixed content. The bionic preview updates instantly.
  2. Adjust Fixation: Controls how much of each word is bolded (10%–60%). Higher = more bolding.
  3. Adjust Contrast (Opacity): Lower = non-bold text appears more faded, creating higher visual contrast.
  4. Adjust Saccade: "All" bolds every word, "Alt" bolds every other, "Skip" bolds every third — adapt to your reading style.
  5. Choose preview theme: Light / Dark / Sepia (eye-care). Automatically matches your site theme.
  6. Click "HTML" to copy the bold-formatted HTML. Paste directly into Notion, blogs, or any HTML-supported platform.

Frequently asked questions

How does Bionic Reading work?

It bolds the first few letters of each word, guiding the eye to scan faster while the brain completes the rest, boosting reading speed.

Can I adjust the bold ratio?

Yes. A slider lets you control what fraction of each word is bolded.

Can I export the result?

Yes. Export as HTML to preserve the bold formatting.

Bionic Reading is a method facilitating the reading process by guiding the eyes through text with artificial fixation points. As a result, the reader focuses on the highlighted initial letters and lets the brain complete the word automatically.
