Does this prove my site is accessible or ADA/WCAG compliant?

No. This is an automated check, and automated tools only catch a portion of accessibility problems — research puts it at roughly a third to a half. They cannot judge whether content makes sense, whether the keyboard order is logical, or what the real screen-reader experience is like. Treat a clean result as a good sign, not a certificate. Genuine compliance needs manual testing and, where it matters, an expert audit.

Which standard and rules do you test against?

We use axe-core, the open-source engine behind many professional tools, and run the WCAG 2.0, 2.1 and 2.2 rule sets at Levels A and AA — including colour contrast (1.4.3), non-text content / alt text (1.1.1), info and relationships (1.3.1), name-role-value (4.1.2), link purpose (2.4.4) and more. Each finding is mapped to its specific success criterion.

Is my data or the pages I scan stored anywhere?

No. We fetch the public page, run the scan in memory and return the report to your browser. Reports aren't saved to an account or database, and the AI alt-text suggestions are generated entirely on your device. Close the tab and the audit is gone.

How many pages can I scan?

The free plan checks up to 3 pages from the URL you enter, following links within the same site. Full-Site Crawl (up to the page cap) and clean, unwatermarked exports are part of Pro.

Why does the alt-text AI take a moment the first time?

The alt-text suggestions reuse our on-device vision model (about 360 MB), which your browser downloads once and then caches. After that it runs locally — on your GPU when available, otherwise your CPU — with no upload and no API call. It's the same engine as the free AI Alt-Text Generator.

Can you scan a page behind a login?

No. We only load public pages and we don't forward cookies or credentials. Pages that require sign-in, or that block automated browsers, can't be scanned.

Why did a page fail to scan?

Individual pages can time out, block bots, or return errors — when that happens we skip just that page and keep going, and list what was skipped. One bad page never stops the rest of the audit.

Accessibility & Alt-Text Audit

Scan a live web page against WCAG 2.1/2.2 (A & AA), see every issue mapped to its success criterion with a plain-English fix, and generate alt text for missing images with on-device AI.

Uses our secure server — your file is processed, then deleted. Never stored.

Coming soon

The Accessibility & Alt-Text Audit is undergoing final security review before launch. In the meantime, the AI Alt-Text Generator is available for single-image alt text. Check back soon.

⚠️ Automated accessibility testing catches only part of what matters and is not a legal compliance certification. Use this as a fast first pass, then verify with manual and assistive-technology testing.

The Accessibility & Alt-Text Audit scans any public web page for WCAG 2.1/2.2 issues — colour contrast, missing labels, heading structure and missing alt text — and offers on-device AI fixes for images; free for up to 3 pages, no account needed.

Key facts

Checks WCAG 2.1/2.2 Level A and AA criteria
Covers colour contrast, missing labels, heading structure and alt text
On-device AI suggests alt text for flagged images
Free for up to 3 page scans, no account required
Only scans public pages — no data is stored
Automated check only — not a legal compliance certification

Paste a page URL

Enter the address of any public web page you want to check. We load it in a real headless browser — the same engine sites are built for — so the audit sees the page exactly as a visitor's browser does, including content added by JavaScript. We only scan public pages; nothing is saved.

We run a full WCAG scan

The page is tested against the WCAG 2.0, 2.1 and 2.2 success criteria (Levels A and AA) using the industry-standard axe-core rules — including colour contrast, form labels, link names, heading structure, language and image alt text. We crawl politely: we respect robots.txt, throttle requests and cap how many pages we visit. The free plan checks up to 3 pages.

Review issues mapped to WCAG

Every issue is grouped by severity and tied to the exact WCAG success criterion it fails, with the element location and a plain-English fix. You get a score per page and for the whole scan — an honest automated signal, not a legal pass/fail.

Fix images with on-device AI

For images missing good alt text, the same on-device AI from our Alt-Text Generator proposes a draft caption — running entirely in your browser, never on a server. Copy individual suggestions or export the whole list, then export the full report as PDF or CSV.
