Who it's for

Who Is It For?

The browser extension is for individuals who need accessibility features on the websites they visit every day — not website owners who want to add accessibility to their site. For that, see the Angstroma Widget.

The extension is designed for people who:

Have low vision and need larger text or higher contrast on any website

Have dyslexia and benefit from specific fonts and reading guides

Are sensitive to motion and need to stop animations on websites that do not respect OS settings

Use keyboard navigation and want a clearer visible focus indicator

Have any combination of needs and want them applied consistently everywhere they browse

No account, no subscription, no sign-in. Preferences are stored locally on your device.

Features

High contrast mode

Toggle high contrast for better text visibility on any website

Color inversion

Invert all colors for extreme contrast or light-sensitive needs

Dyslexia-friendly font

Switch to a font designed to reduce letter confusion

Text size adjustment

Increase text size beyond what native browser zoom provides

Reading guide

A horizontal mask that follows your cursor to help reading focus

Text to speech

Select any text on a webpage and have it read aloud

Focus highlight

Enhanced focus indicators for keyboard navigation

Reduce motion

Override websites that ignore prefers-reduced-motion

Pause animations

Stop CSS animations and GIFs on any website

Monochrome mode

Remove all colors for users sensitive to color stimulation

Letter spacing

Increase letter spacing for better readability

Line height

Increase line height to reduce visual crowding

Privacy

The browser extension:

Does not require an account — use it anonymously

Stores preferences locally — on your device only, not on our servers

Does not track your browsing — we do not collect URLs you visit or content you view

Does not inject ads or analytics into websites you visit

Does not communicate with Angstroma servers unless you explicitly sign in to sync preferences

Our extension is open about exactly what permissions it requests and why. We will publish the required permissions list and their justification in the Chrome Web Store listing.
