If you've worried about accessibility, you've almost certainly been offered the dream solution: a small widget you paste onto your store that promises instant ADA/WCAG "compliance" for a monthly fee. Before you reach for your card, here's the honest picture — because this is one area where the easy answer is the wrong one.
An overlay (sometimes called an "accessibility widget" or "AI accessibility solution") is a piece of code you add to your site. It typically shows a little accessibility icon that opens a menu — bigger text, contrast modes, a dyslexia font — and claims to automatically detect and fix accessibility problems in the background. The pitch is irresistible: paste one line of code, pay monthly, and your compliance worries vanish.
The fundamental problem is that an overlay sits on top of your website and tries to patch issues from the outside, with a script. But many accessibility problems live in the underlying structure and content, where a bolt-on script simply can't reach:
This isn't a fringe opinion. Accessibility experts and disability advocates have widely and publicly criticised overlays — a large group of accessibility professionals signed an open letter against them — and many screen-reader users report that overlays interfere with the assistive technology they already use, sometimes making sites harder to use, not easier.
Here's the part that surprises people: rather than preventing lawsuits, sites using overlays have repeatedly been named in them. Plaintiffs and their lawyers are well aware of overlays and specifically target sites that rely on them, precisely because the overlay hasn't fixed the real underlying issues. So the "compliance shield" you paid for can become a flag that says "this store took a shortcut." An overlay does not, on its own, make a site conform to WCAG.
Accessibility feels overwhelming and technical, so a widget that makes it disappear for a monthly fee is a very appealing story. But there is no script that can read the meaning of your content, restructure your code, or make a custom checkout genuinely usable with a keyboard and screen reader. Real accessibility lives in your site — which means the real work is in your site too.
The honest path isn't as instant, but it's the only one that genuinely helps disabled customers and stands up to scrutiny:
It's more effort than pasting a widget — but it's effort that actually makes your store usable and demonstrates genuine good-faith effort, which is what truly reduces your risk.

So if a tool promises instant, one-click compliance: be sceptical. The honest answer is that you can't paste your way to accessibility — but you can find out exactly where you stand and fix what matters, which is worth far more than a reassuring icon in the corner of your screen.
