The Problem

Accessibility testing is fragmented.

Every tool catches different issues. Manual audits are expensive. PDFs are ignored. Nobody fixes anything because the remediation workflow is broken.

⚙️axe DevTools / WAVE

Catches DOM-level violations. Cannot audit PDFs, understand semantic intent, or fix anything.

📄Adobe Acrobat

Decent PDF checker. Desktop-only, expensive per seat, no web auditing, no API, no batch processing.

💰Manual Audits

Gold standard for quality. But $5K–$25K per audit, weeks of turnaround, no iterative fix-retest workflow.

🎯PARIS

All engines in one bench. Web + PDF + document auditing. Fix in-browser. Re-test instantly. veraPDF certification.
