Accessibility Statement
accessibility.chat is committed to ensuring digital accessibility for all users, including people with disabilities. We continually work to improve the user experience and apply the relevant accessibility standards.
Conformance Standard
We aim to conform to the Web Content Accessibility Guidelines (WCAG) 2.1 Level AA. These guidelines explain how to make web content more accessible to people with a wide range of disabilities, including visual, auditory, physical, speech, cognitive, language, learning, and neurological disabilities.
Measures We Take
- 18px root font size with minimum ~16px for all text site-wide (no text smaller than text-sm at 0.875rem)
- Color contrast ratios targeting WCAG AA (4.5:1 for normal text, 3:1 for large text)
- Visible focus indicators for all keyboard-interactive elements
- Semantic HTML with proper heading hierarchy
- Skip navigation link on every page
- ARIA landmarks (banner, navigation, main, contentinfo) on all pages
- Descriptive alt text for informative images; decorative images properly marked
- External links indicate when they open in a new window
- Support for reduced motion preferences
- Support for high contrast mode
- Keyboard-accessible interactive elements including our chat widget
AI-Generated Content
Our articles are generated by AI analysts and pass through a 6-stage editorial review pipeline before publication. Each article includes a transparency disclosure identifying the AI analyst and their analytical lens. We enforce accessible content standards in our generation process, including proper heading hierarchy (H2 and H3 only), descriptive link text, and fact-checked external links.
Luke Tool Coverage
Luke is a free screening and triage assistant. Depending on the request and available evidence, it combines source-linked conversation, deterministic document checks, veraPDF PDF/UA validation, and four labeled web passes: Axe, Aberio, Luke Lens, and Web Audit Lite. Results help users understand risk and next steps before formal remediation, certification, or a manual audit.
| Capability | Luke Can Help With | Still Requires |
|---|---|---|
| PDF text review | Policy language, ADA/504 risk signals, remediation guidance, and summary memos. | Verification that the PDF has a usable text layer and that extracted text is complete. |
| PDF inspection | Text-layer checks, deterministic PDF/UA checks, veraPDF findings, structured QA, and remediation planning. | Visual, reading-order, assistive-technology, OCR, and remediation review. A Luke result is not PDF/UA certification. |
| Web assessment | Axe, Aberio, Luke Lens, and Web Audit Lite findings, labeled by engine with page and rule evidence. | Complete keyboard, focus, contrast, reflow, browser/AT, task-flow, and manual user testing across the site. |
Known Limitations
Despite our efforts, some content may not yet be fully accessible. In particular:
- Some older articles may contain heading hierarchy issues that predate our current editorial standards
- Automated results can miss context-dependent failures, including meaningful alt text, reading order, task completion, and assistive-technology behavior
- Third-party embedded content and browser notification behavior may have accessibility gaps outside our direct control
Feedback & Contact
We welcome feedback on the accessibility of this site. If you encounter any barriers or have suggestions for improvement, please contact us:
We aim to respond to accessibility feedback within 2 business days.
Assessment & Review
This site is reviewed using automated checks, AI-assisted analysis, and targeted manual review. We publish limitations rather than treating automated output as proof of conformance. Luke assessments identify their engines, scan mode, evidence, and remaining human-review requirements when those details are available.
