About OpenDyslexic for Chrome
OpenDyslexic for Chrome is the plain version of a dyslexia aid: it replaces the fonts on a web page with OpenDyslexic, a free typeface designed to make reading easier for people with dyslexia. Each letter has a heavier bottom, which the project says keeps letters steady and reduces confusion.
There is little to learn. Install it, toggle it on, and pages are reformatted in that font, with an optional low-contrast setting. The listing says it is open source, and the code is on GitHub. The Chrome listing has 225 ratings averaging 4.3, was last updated on 30 July 2026, and says the developer will not collect or use your data. The listing credits Robert James Gabriel, who also founded Helperbird, as maintainer.
Its simplicity is also the limit. It replaces all fonts on a page rather than offering fine control. It offers none of the rulers, tints or reading aloud that Helperbird adds. We cannot say a particular font helps every reader, so try it for a few days. The README mentions Firefox and Edge versions, but we could not confirm store listings. If a font swap is all you need, it is free and easy.

Permissions
It runs a script on web pages so it can override their fonts, and asks only for the active tab and storage permissions.
