Short answer

How can I check web accessibility with my AI?

Give your AI a URL and ask it to run an audit. It uses Google Lighthouse to pull real-time data on accessibility violations and best practice failures. You get a clear list of what needs fixing.

Where every issue lands.

Audit outcomes

The AI processes the raw audit data into actionable categories.

VIOLATIONS

Accessibility failures

The AI identifies specific WCAG failures found in the audit. You get a list of elements that break compliance.

BEST PRACTICES

Optimization gaps

Your agent flags areas where the site meets basic standards but misses performance or SEO best practices.

REPORTS

Data summaries

The AI condenses the technical Lighthouse JSON into a readable summary of your site's health.

HUMAN

Manual fixes

The AI points out the errors, but you must go into your code to actually apply the accessibility patches.

The workflow

What your AI does when the URL arrives.

The AI handles the heavy lifting of fetching and interpreting technical audit logs.

  1. Fetch live data
