PDF Accessibility Hub

PDF Accessibility Hub is a SaaS product built and operated by Innovait Systems that makes PDFs compliant with the PDF/UA-1 accessibility standard. Upload a document, and the engine auto-tags and remediates its structure; automatic point tools then verify the result — a PDF/UA & Matterhorn compliance report, reading-order checks, alt-text generation, and content-integrity analysis — and an editor covers the cases that need fixing by hand.

Standard

PDF/UA-1 (ISO 14289-1) · Matterhorn Protocol

Model

Credit-metered SaaS, self-serve + enterprise

Stack

Next.js · Java (Apache PDFBox, veraPDF) · Supabase · Razorpay

Problem Space

Accessibility regulations (the European Accessibility Act, Section 508, and national equivalents) require documents to be usable with screen readers. Making a PDF conform to PDF/UA is slow, expert work — tagging the structure tree, fixing reading order, adding alt text — and most teams have no way to measure where a document currently stands.

The goal was to turn that specialist workflow into something a non-expert can run in minutes, and an expert can finish by hand.

Solution

  • An engine that auto-tags and remediates a document's structure.
  • Six standalone point tools — compliance report, reading-order verification, content integrity, visual compare, alt-text, and tag cleaner — each returning a report.
  • An interactive editor to fix the tag tree by hand and export a compliant PDF.
  • Credit-metered billing with GST-compliant invoicing, for both self-serve and enterprise customers.

What It Delivers

  • A pass/fail PDF/UA verdict, in the checkpoint terms an auditor uses.
  • Automatic remediation that resolves many common conformance failures.
  • Downloadable compliance reports and a tagged, standards-compliant output PDF.

Engineering

The accessibility engine is built on Apache PDFBox and veraPDF, wrapped in a warm-JVM service for interactive editing. The product surface is a Next.js application on a self-hosted Supabase stack, with metered billing through Razorpay and GST-compliant tax invoicing.
