  description

  Web Accessibility Checker helps you catch common WCAG accessibility problems on the actual page you’re working on—with one click from the toolbar.
  
  What it does：
  Runs automated checks aligned with WCAG using a bundled axe-core engine (no remote executable code).
  
  Opens a guided audit experience so you can move between scan setup, results, and remediation-oriented views.
  
  Highlights the element related to an issue on the real page, so you’re not guessing which button, link, or heading failed.
  Surfaces plain-language explanations first, with deeper technical details available when you need them.
  
  Supports practical workflows like preset scan levels (for example quick vs fuller coverage) so teams can balance speed and thoroughness.
  
  Why install it：
  Shipping accessible experiences protects users, reduces legal risk, and improves SEO and usability for everyone. This extension makes routine WCAG checks something you can do in seconds during design, development, or QA—before issues reach production.
  
  Who it’s for：
  Developers, designers, content editors, and accessibility champions who want credible, standards-based signals on real pages without juggling separate tools for every small change.
  
  Important note：
  Automated testing finds many issues, but it cannot replace manual checks such as full keyboard paths, screen reader behavior, and real task completion. Use this extension as a high-signal first pass—then validate what matters most with human review and assistive technology where appropriate.

  Find and fix accessibility issues on any web page — without leaving the page you're testing.
  
  AristAI Web Accessibility Checker scans the page you're on for WCAG accessibility problems, shows you exactly where each one is, and gives you clear, copy-ready guidance to fix it. It's built for developers, designers, QA, content authors, and anyone responsible for WCAG 2.1 / 2.2 AA, ADA, Section 508, or EN 301 549 compliance.
  
  WHY INSTALL IT
  
  • Catch issues other one-click scanners miss. Most checkers only see the page as it first loads. This one runs a full scroll-through sweep and safely opens collapsed sections, dropdown menus, and dialogs first — so it also checks content hidden inside accordions, mega-menus, and pop-ups.
  • See problems in context. Every finding is highlighted on the real page; the checker scrolls to where it's visible and re-opens the menu or dialog it lives in, so you're never hunting for a selector.
  • Fix faster. Each issue comes with the exact WCAG success criterion, a reference link, why it matters, and copy-ready fix instructions.
  • Private by default. The accessibility analysis runs locally in your browser, and a scan never clicks through, navigates away, or submits forms.
  
  WHAT IT CHECKS
  
  • Color and contrast (including text recolored on hover/focus)
  • Forms and labels
  • Keyboard and focus — visible focus indicator (2.4.7), tab/reading order (2.4.3), keyboard reachability (2.1.1), and dialog focus
  • Images and media (alt text)
  • Page structure — headings, landmarks, lists, regions
  • ARIA, roles, states, and accessible names
  • Language, tables, media & timing, viewport & touch targets
  • Broken or unreachable links, and spelling in visible copy
  
  Choose a Quick scan, the recommended WCAG A/AA preset, or a Full audit (AAA + best practices). Review results in an Executive Summary with a Health Score, then filter by severity, category, or a specific check.
  
  BUILT-IN TOOLS
  
  • Color Contrast Checker — pick any element with an eyedropper and get pass/fail plus fix suggestions
  • Image Alt Text Checker — review and classify every image's alternative text
  • Heading Structure Checker — see the page's heading outline at a glance
  • Page File Inventory — list every PDF, Office file, image, audio, and video on the page, then export a CSV or download them as a ZIP
  
  Use it as a side panel or an in-page overlay.
  
  Part of the AristAI Accessibility Suite (accessibility.aristai.io), which adds batch checking, remediation, and accessible-format export for PDFs, Microsoft Office files, LMS content (Canvas, D2L, Blackboard), web pages, and video.
