Overlay widgets vs source-level accessibility
Ecommerce teams under ADA and EAA pressure often get sold the same promise: install a widget and “get compliant.” That promise usually means an overlay — a script that draws assistive UI on top of pages without fixing missing labels, alt text, or keyboard traps in the source.
What overlays do (and do not do)
Overlays can offer user-facing tools (contrast, font size, menus). They do not rewrite the HTML your CMS, Shopify theme, or headless storefront serves. Screen readers and keyboard users still hit the underlying markup.
AccessioAI does not sell overlay “instant compliance,” and we will not claim a single scan or widget makes a site fully conformant.
What source-level monitoring does
- Find issues against WCAG 2.2 AA on real public URLs
- Prioritize by severity for remediation backlog
- Fix what the origin serves with human review of AI suggestions
- Monitor so new pages and SKUs do not reintroduce the same defects

Bottom line
If a vendor’s primary story is “no code changes required” or “compliant in minutes,” treat that as an overlay pitch. Prefer tools that show source findings and require human review of AI output.
