The Accessibility Gap in AI Interfaces Nobody Is Shipping Around
Most AI teams run accessibility audits on their landing pages. Almost none run them on the chat interface itself. The gap isn't laziness — it's that the tools don't exist. WCAG 2.2 has no success criterion for streaming content, no standard for non-deterministic outputs, and no guidance for token-by-token delivery. Which means every AI product streaming responses into a <div> right now is operating in a compliance grey zone while breaking the experience for a significant portion of its users.
This isn't a minor edge case. Blind and low-vision users report information-seeking as their top AI use case. Users with dyslexia, ADHD, and cognitive disabilities are actively trying to use AI tools to reduce reading load — and the default implementation pattern actively makes things worse for them.
