It can be a bit daunting to make a web application compliant with assistive technologies when you yourself never use them, and you feel like you don't yet know anything about directives like the Web Content Accessibility Guidelines (WCAG). Intelligent guided accessibility tests are one category of tools that help test if you've done the right thing without needing to be an expert on accessibility. These tools are browser extensions that scan your website, summarize how assistive technology would interpret it and then ask you a set of questions to confirm whether the structure and elements you created are as intended. We've used axe DevTools, Accessibility Insights for Web or the ARC Toolkit on some of our projects.
