What It Actually Does

A series of DOM transformations that simulate screen reader behavior.
Content Removal: Removes elements hidden from assistive technology (aria-hidden="true", role="presentation"). Removes decorative images and SVGs.

Content Replacement: Replaces images that have alt text with visible text labels. Replaces aria-labelledby elements with their referenced text.

Content Surfacing: Identifies and highlights all visually hidden elements (.sr-only, clip patterns). Surfaces hidden text that only screen readers can access.

Two Configuration Options

On activation, you choose how deep the simulation goes.
Include element roles? Appends [link] and [button] role labels to interactive elements, showing how a screen reader announces them.

Strip all styles? Removes every stylesheet on the page. Reveals sections that are currently invisible but would be announced by screen readers. Useful for catching content hidden behind JavaScript show/hide toggles.

What You'll Find

Run it on any page. Common issues it exposes instantly.
Images without alt text - flagged visually so you can see exactly which ones.

Decorative images with non-empty alts - screen readers read these unnecessarily.

ARIA labels that don't match - visible text says one thing, aria-label says another.

Hidden content announced to screen readers - text that sighted users never see but assistive technology reads aloud.
