S76 Ep 7The Hidden Trouble with Tables
In this episode of Chax Chat, Chad and Dax tackle one of the most misunderstood areas of document accessibility: tables. While they may seem simple to build, the real challenge is designing them in a way that works for assistive technology. We break down how screen readers navigate tables, why column and row headers matter, and how small design decisions can dramatically impact the user experience. From common pitfalls like overcomplicated layouts and unclear headers to practical tips you can apply immediately, this episode is packed with real-world insight. Whether you create, design, or remediate documents, you'll walk away with a clearer approach to building tables that are not just accessible, but truly usable.
S6 Ep 6The One Remediation Tool You Should Have...
What's the best tool for making PDFs accessible? It's the question we get constantly, and the honest answer might surprise you. There isn't one. In this episode of Chax Chat, Chad and Dax break down how the "best" accessibility tool depends entirely on your starting point. Are you working in Word, InDesign, PowerPoint, Google Docs, or Canva? Do you have a tagged PDF, an untagged PDF, or a scanned document? Each scenario changes the strategy. We discuss why "born accessible" is always better than heavy remediation, when Adobe's auto-tagging can actually help, why tools like MadeToTag and Access Word continue to be game changers, and how platforms like CommonLook, PDFix, PREP, and Grackle fit into the workflow. We also talk about handling scanned PDFs, the realities of screen reader testing, and why bookmarks aren't the navigation solution many people think they are. If you've ever felt overwhelmed trying to choose the right accessibility tool, this episode will help you stop chasing a magic solution and start making smarter decisions based on context. Every other week, we unravel accessibility so you can build more inclusive, compliant, and practical documents.

S6 Ep 5Microsoft's MathML Win and Adobe's AI Alt Text Experiment
In this episode of ChaxChat, Dax Castro and Chad Chelius unpack two very different approaches to accessibility innovation. First, they dive into Microsoft's implementation of MathML in Word and PowerPoint and why it represents a genuine win for accessible math. By carrying MathML through to the PDF export with proper tagging and screen reader support, Microsoft demonstrates what it looks like when accessibility is built into the workflow rather than patched on later. They then turn to Adobe InDesign's new AI-generated alt text feature and explore where it helps, where it falls short, and why turning it on by default raises important concerns. The conversation highlights the difference between proven accessibility solutions and experimental AI features, emphasizing the need for human oversight, informed decision-making, and realistic expectations as tools continue to evolve.
S6 Ep 4Accessible Forms: PDF or Web?
Accessible forms are more than a technical checklist. They require smart decisions about usability, workflow, and long-term maintenance. In this episode of Chax Chat, Dax Castro and Chad Chelius are joined by Walt Zielinski, a web developer with extensive experience building accessible form experiences. The conversation focuses on a key question: when should you use a web form versus a PDF form? Together, they explore real-world considerations like data collection, offline access, cost, maintenance, and who is responsible for supporting the form over time. They also cover common accessibility issues that frequently get overlooked, including error identification, focus order, color reliance, target size, and the correct use of checkboxes and radio buttons. This episode offers practical guidance for designers, developers, and document professionals who want forms that actually work for everyone.
S6 Ep 3What 2025 Taught Us About Accessibility - and What Comes Next
In this episode, Dax Castro and Chad Chelius take a thoughtful look back at the accessibility lessons that defined 2025 and share what they are most excited about heading into 2026, drawing directly from real client work, remediation challenges, and conference conversations. They unpack why tables and forms continue to be the most persistent pain points for document accessibility, discuss hard-earned wins from complex remediation projects, and reflect on where current tools still fall short. The conversation also explores realistic expectations for AI in accessibility, emerging assistive technologies that show genuine promise, and the conferences and community spaces shaping the year ahead. It is an honest, practical discussion grounded in experience, aimed at helping accessibility professionals and content creators learn from the past while preparing for what comes next.
S6 Ep 2The Real Cost of Accessibility: Tools, Time, and ROI
In this episode Dax Castro and Chad Chelius break down the real-world value of accessibility tools. From essential free tools like NVDA and color contrast analyzers to powerful paid solutions like CommonLook, Access PDF, PDFix, and more, they discuss what actually saves time, what improves quality, and what's worth the investment. If you're creating or remediating accessible documents and wondering whether paid tools are justified, this conversation offers practical insights, honest tradeoffs, and ROI-driven advice grounded in everyday accessibility work.
