Digital Accessibility

We help organizations make their websites, apps, documents, and digital products accessible to people with disabilities.

Our services include audits and Voluntary Product Accessibility Templates (VPATs), which are used to prepare Accessibility Conformance Reports (ACRs), along with Portable Document Format (PDF) accessibility and artificial intelligence (AI) accessibility.

What Is Digital Accessibility?

Digital accessibility means designing and building websites, apps, documents, and other digital experiences so people can interact with them using different ways of access.

It includes how people navigate, read, listen to, understand, and interact with digital content, whether they use a keyboard, screen reader, magnification, voice input, other assistive technology, or no assistive technology at all. Standards such as the Web Content Accessibility Guidelines (WCAG) matter, but so does whether people can actually use what you create.

What We Offer

C4AT offers practical digital accessibility services that can stand alone or work together as your needs evolve.

What Current Research Shows

Two useful resources put automated findings in context and show why human review and user feedback remain essential.

What AI Can Test—and What It Cannot

AI and automated tools can support accessibility work, but they do not replace expert manual review or feedback from people with disabilities.

At a glance: automated findings tell only part of the story. Manual review and feedback from disabled users reveal context, interaction, and usability issues that tools cannot fully assess.
