There are a few very specific tasks like re-writing content at lower reading levels that you might utilize AI for. But remember that you’ll still need to read and edit this content — the AI tools don’t always get everything right. You’ll still also have to make sure (either manually or with a plugin like Accessibility Checker) that the H-tag structure is semantically nested correctly.
But be really wary of AI-based js “overlay plugins” for accessibility. They often make the pages LESS accessible by conflicting with the user’s existing tools, only find about 30% of issues (for instance, they can tell you that you HAVE alt text, but not whether it’s good alt text), and there are some issues they CAN’T fix (like keyboard navigation issues). Additionally, there are some growing concerns about those plugins and privacy compliance. You can find more info on those overlay plugins here: https://overlayfactsheet.com/
