Dark Anchor Reader

Dark Anchor transforms any webpage into a focused, accessible reading environment built around two core ideas: reduce visual noise, and give your eyes something consistent to hold onto.

Dark Mode
Applies a clean dark background with high-contrast text. Brightness is fully adjustable from near-black to soft charcoal.
Semantic Grammar Coloring
Every word is classified and color-coded by its grammatical role, inspired by VSCode's syntax highlighting:

🔵 Determiners — the, a, my, this, their
🟣 Conjunctions — and, but, because, however
🩵 Prepositions — of, in, from, through
🩴 Linking verbs — is, was, can, become
🟡 Proper nouns — names, places, brands, acronyms
🟢 Numbers — numerals and ordinals
🟠 Adverbs — very, quickly, never, probably
🔴 Adjectives — big, cold, important, simple
🧡 Headers — h1–h6 highlighted in warm orange

Dyslexia Assist Mode
Toggle feature applying evidence-based text spacing, increased letter spacing, generous line height, and wider word spacing, without changing the font.

Color-Only Sites
Add any site to a whitelist to keep its original background while still applying grammar coloring. Perfect for sites that already have a dark theme.
