How the check works
Paste the address of any public page.
We load it in a real browser at desktop and phone size and run more than 40 automated checks.
You get a score, every problem grouped by type, and the exact fix: code before and after, steps for your platform and a prompt for AI tools.
What the ADA means for websites
The Americans with Disabilities Act (ADA) prohibits discrimination against people with disabilities. For websites, two parts matter. The ADA Title II rule requires US state and local government websites and apps to meet WCAG 2.1 AA, with deadlines that depend on the size of the body.
Title III covers businesses open to the public. It names no technical standard; WCAG 2.1 AA is the level courts and settlements commonly refer to.
Overlays and widgets add a script on top of a site and do not change the code that causes the barriers. AccessibilityBrief shows what to change in the code itself, and the results mark which problems concern WCAG 2.1 AA so you can fix those first.
What the checker tests
Each check links to a guide that explains the problem, who it affects and how to fix it.

What an automated checker cannot tell you
Automated tests can check whether an image has a text alternative, but not whether the text describes the image well. They cannot judge keyboard flow or how a screen reader announces a complex widget. Every report includes a manual checklist for these parts.
Questions and answers
Can this checker tell me whether my website meets the ADA?
No tool can. The ADA is a law, and whether it applies and is met depends on your situation. The checker shows the WCAG 2.1 AA problems automated tests find on your pages, which is the technical level ADA cases commonly refer to. Manual testing and, if needed, legal advice cover the rest.
Which WCAG level matters for the ADA?
The ADA Title II rule names WCAG 2.1 AA. For Title III no standard is written into the law, but WCAG 2.1 AA is the level courts and settlements commonly refer to.
Does an accessibility overlay solve ADA issues?
Overlays add a script on top of your site; they do not change the code that causes the barriers, and disability advocates have criticised them. AccessibilityBrief never adds a script to your site.
Is the checker free?
Yes. Checking one page is free and needs no account. A one-time audit of a whole site costs $19, and monitoring plans start at $19 a month.
How can I keep a record of what I fixed?
Paid reports include a PDF, a WCAG evaluation report and the scan history, so you can show what was found and fixed over time. The statement generator drafts an accessibility statement for your site.
Check the whole site, not just one page
A one-time audit for $19 scans up to 300 pages and unlocks every fix, the PDF report and the WCAG evaluation report. Monitoring plans rescan on a schedule and tell you when new problems appear.
