BioRead

About

BioRead makes reading on the web easier and more comfortable.

Unlike other extensions that use a fixed bold percentage, BioRead uses an adaptive algorithm that adjusts emphasis based on word length. Short words get lighter treatment, long words get stronger anchoring, and common filler words fade into the background. The result feels noticeably smoother than flat-ratio bolding.

Reading Modes:
- Standard: balanced bionic reading for everyday browsing
- ADHD: narrower width, increased spacing, focus dimming to reduce overwhelm
- Dyslexia: OpenDyslexic and Lexend fonts, increased letter and word spacing for easier decoding
- Speed: aggressive bolding and tight layout for fast scanning
- Focus: paragraph spotlight that dims everything except what you're reading
