HTML accessibility tree

Paste HTML and see its accessibility tree — the roles and accessible names a screen reader works from — computed locally in 22.79 kB of WebAssembly.

Copy

The tree is Markdown: one list item per accessible node, role then accessible name. Content that produces no accessible node — wrapper divs, unlabeled decoration, aria-hidden subtrees — simply doesn't appear, which is the point: if a control is missing here, a screen reader can't reach it either. Handles documents up to 256 KiB.
