# Bionic Reading Converter

> Bold the leading letters of each word to guide the eye through long text.

Bionic reading bolds the first few letters of every word so the eye fixates there and skims the rest, which some readers find speeds them up. Choose a fixation strength and output as HTML, Markdown or Unicode bold that survives pasting into any application.

## FAQ

### Does bionic reading actually work?

Evidence is mixed. Independent studies have not reproduced the large speed gains originally claimed, though some readers report it helps focus. Treat it as a preference, not a proven technique.

### Is Unicode bold accessible?

No. Those are mathematical alphanumeric symbols, not styled letters, so screen readers either skip them or read them character by character. Use the HTML output on any page that needs to be accessible.
