No Emulators, No Simulators
Accessibility professionals know screen reader emulators and simulations miss critical bugs. For example, the "ChromeVox Classic" browser extension is an easy way to try a screen reader with Google Chrome.
However, it only simulates part of the typical screen reader experience because it reads the DOM directly. It cannot test a native app or any UI outside of the webpage and doesn't call the OS accessibility APIs, like NVDA, VoiceOver, Narrator, and JAWS do. Worse, ChromeVox makes up only 0.3% of surveyed screen reader usage.
Assistiv Labs provides access to real screen readers, like NVDA, VoiceOver, Narrator, JAWS, and ZoomText/Fusion, which covers over 96% of primary screen reader usage, according to WebAIM.
Learn How to Test Screen Readers
Select plans include free training to get you up to speed on how screen readers work and how to use them to improve your website's compatibility with screen readers and other assistive technologies.
Mac to PC Keyboard Shortcuts
If you've ever tried to set up a virtual machine to test screen readers, you've probably been frustrated by screen reader keyboard shortcuts not working. For example, to show the Elements List with NVDA, you use Caps lock + F7. This won't work because MacOS treats the caps lock key differently than Windows.
Assistiv Labs remaps your keyboard shortcuts on the fly, letting you choose alternatives that work out of the box.
