ANDI (Accessible Name & Description Inspector) is a "favelet" or "bookmarklet" used by web developers and testers to inspect web content for accessibility.
ANDI provides a simple interface with which to:
- Automatically detect potential accessibility issues.
- Reveals what a screen reader should say for interactive elements.
- Get practical suggestions to improve accessibility.

Ensure that Chrome's Bookmarks Bar is set to always show.

- Unfortunately, Chrome does not offer a simple keyboard accessible alternative.
ANDI is now installed to Chrome and ready to be launched.
Launch ANDI by clicking on the favorite/bookmark labelled "ANDI" that was added to the Favorites/Bookmarks Bar in the browser's toolbar. ANDI will analyze the test page and inject itself onto the top of the page.
Using ANDI is fairly intuitive, however some understanding of HTML is needed. For thorough documentation of all features, visit: ANDI Help.
