A collection of free bookmarklets that test for common accessibility issues directly in the browser. Each one maps to its related WCAG 2.2 success criteria. Want access to SpotCheck in a single view? No problem. Download the browser extension to access them in devtools. Outlines every ARIA and HTML landmark region and flags ones missing an accessible name or duplicated.

The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
