No ARIA is better than bad ARIA

Something I'm desperately keen to see is AI-assisted accessibility testing.

I'm not convinced at all by most of the heuristic-driven ARIA scanning tools. I don't want to know if my app appears to have the right ARIA attributes set - I want to know if my features work for screenreader users.

What I really want is for a Claude Code style agent to be able to drive my application in an automated fashion via a screenreader and record audio for me of successful or failed attempts to achieve goals.

Think Playwright browser tests but for popular screenreaders instead.

Every now and then I check to see if this is a solved problem yet.

I think we are close. https://www.guidepup.dev/ looks extremely promising - though I think it only supports VoiceOver on macOS or NVDA on Windows, which is a shame since asynchronous coding agent tools like Codex CLI and Claude Code for web only run Linux.

What I haven't seen yet is someone closing the loop on ensuring agentic tools like Claude Code can successfully drive these mechanisms.

Not a joke. If truly you want a properly functioning website for blind/bad sight/ Step 1 would probably be to put on a blindfold and go through your website with a screenreader (cmd + f5 on a mac).

I'd argue it's pretty hard on Windows.

NVDA hasn't worked for me since Windows 11.

Narrator + IE and Narrator + Chrome basically work but make ARIA look like vandalism. It will just be reading the text and blurt out "LANDMARK WILL ROBINSON!" in the middle of the text for no obvious reason and doesn't do it the same very time. It's basically possible to use either one of those but Narrator + Firefox is especially spastic and blurts out random landmarks and ARIA junk to the extent that it's really difficult to evaluate.

I mean, that's part of the problem, there is a spec for how HTML is supposed to be rendered, but ARIA is not specific about how ARIA markup is rendered which might means tools could bend to meet users' needs but it also means there is no such thing as "I've convinced myself that my ARIA markup is proper and will work for everyone with mainstream tools"
