Why use AI for accessibility?

Web accessibility is law in most jurisdictions and table stakes everywhere else. WCAG 2.1 requires every meaningful image on a public site to have alt text; ADA lawsuits target sites that don't comply. An AI image description tool tuned for accessibility produces compliant alt text in the right length, tone, and format — and a longer description for complex images that need more than alt text alone can carry.

The AI image describer returns three forms of the description in one click: a detailed paragraph, a short caption, and a WCAG-compliant alt text under 125 characters. For most accessibility workflows, the alt text is the field you'll use most — but the longer description is there when you need more depth.

Common accessibility workflows

WCAG 2.1 compliance

Every Level A success criterion requires non-text content to have a text alternative. The AI generates compliant alternatives at scale.

ADA compliance for ecommerce

Most ADA lawsuits cite missing alt text as evidence. Bulk-describe your product images to remove the easiest target.

Section 508 (US Federal sites)

Federal sites and contractors need Section 508-compliant content. The AI produces text alternatives that meet 508 requirements.

EAA (European Accessibility Act)

Effective June 2025, the EAA requires accessible digital content across the EU. Alt text on every image is non-negotiable.

Education / LMS content

Course materials, slides, and PDFs are required to be accessible. Alt-text every image in your LMS.

Screen-reader-first publishing

Some publishers (research, government, accessibility-first orgs) draft alt text alongside the image — the AI is a starting point that gets refined by an accessibility editor.

Frequently Asked Questions

Is the alt text WCAG 2.1 compliant?
Yes — concise (under 125 characters), descriptive, no "image of" prefix, no redundant punctuation. Follows the most current alt-text guidance.
What about complex images that need a long description?
The tool returns both: a short alt text for the alt attribute, plus a longer description that you can put in a longdesc, an adjacent <figcaption>, or a separate description page.
Will it pass an automated accessibility check?
Yes — automated checkers (axe, WAVE, Lighthouse) verify that some alt text exists, and this tool produces good-quality alt text. For human accessibility audits, the AI output is a strong starting point that an accessibility consultant can refine.
Can I use it for ADA compliance work?
Yes — for both proactive compliance and remediation work after a lawsuit or demand letter. Bulk-describe images first, then have an accessibility consultant review the output.
Does it handle decorative images?
Decorative images should have alt="" (empty alt). The AI always produces text — override with an empty alt for purely decorative images.
What about charts and infographics?
The AI describes them at a high level. For complex data visualizations, alt text alone isn't enough — pair the AI's description with a data table or long-description page.
Can I bulk-process images for an accessibility remediation project?
Free tool: 3 per day per IP. For bulk: AI Analyzer Pro inside the dashboard (unlimited) or API v2 batch processing for entire site remediations.
