Welcome to Bionic Reader

Paste any raw text or markdown on the left. The right side re-renders it with the leading letters of each word bolded so your eyes can jump between fixation points faster.

• Tune the fixation strength to bold more or fewer letters.
• Switch fonts — including a dyslexia-friendly option.
• Pick a theme that's easy on your eyes.
