LexiFont — Dyslexia Font, Reading Ruler & OpenDyslexic

About

LexiFont turns every web page into a dyslexia-friendly reading surface.

Pick from four research-backed fonts — OpenDyslexic, Lexend, Atkinson Hyperlegible and Comic Neue — and they apply instantly on every website you visit: Gmail, Wikipedia, Medium, your company intranet, online courses, news sites, anything in Chrome.

Add a gentle reading ruler that follows your cursor line by line, a soft tinted overlay for readers with Irlen syndrome or visual stress, and fine-grained control over font size, letter spacing, word spacing and line height. All settings sync across your Chrome installs. All processing happens locally. Zero tracking.

WHICH FONT SHOULD YOU USE?
━━━━━━━━━━━━━━━━━━━━━━━━━━

OpenDyslexic (free forever)
Heavily weighted letter bottoms anchor characters on the baseline. Designed specifically to make rotations (b/d, p/q) harder. A good first choice if you rotate or flip letters.

Lexend (Pro)
Built by Thomas Jockin with reading specialist Dr Bonnie Shaver-Troup. Wider proportions, reading-speed research behind every letterform. Great for long articles and technical text.

Atkinson Hyperlegible (Pro)
Designed by the Braille Institute. Every character is drawn to be maximally distinct — 0 vs O, a vs o, I vs l. Excellent for low vision and for dyslexic readers whose issue is letter confusion.

Comic Neue (Pro)
A reading-grade rework of Comic Sans. Informal, open letterforms that many dyslexic readers find calming, without the spacing problems of the original.

PRIVACY
━━━━━━━━━━━━━━━━━━━━━━━━━━

LexiFont was designed so that we literally cannot see what you read. The extension runs entirely inside your browser. No analytics scripts. No tracking pixels. No telemetry.

What stays in your browser:
- Your font choice & slider preferences
- Your per-site rules
- License state (Pro/trial/free)

The only network request LexiFont ever makes is to verify your Pro license key with our payment processor — only if you choose to activate one.
