From untagged PDFs to validated PDF/UA – AI‑assisted, not fully automated

The AI handles the laborious structural work – tags, reading order and alt-text suggestions. Expert review and sign-off stay with your specialists. We don't promise full automation, but a transparent path to validated PDF/UA conformance.

PDF/UA + WCAG Transformation with validation and quality reports
One workflow Upload, structure, tags, reading order, and alt text in one pipeline
European & GDPR For organizations with high requirements around privacy and traceability

Not a single tool – a continuous pipeline built for exactly this use case.

01
Pipeline-driven, not piecemeal. From structure to tags to validated PDF/UA – instead of manual work in Acrobat.
02
No black box. The accessible document structure can be reviewed and understood directly in the browser.
03
Humans stay in control. Accessibility cannot be fully automated. Human-in-the-loop review is a fixed part of the process – with a complete quality report.
01
File Upload
Upload any PDF – scanned or digital. The pipeline handles the pre-structuring, the result is then reviewed by people and adjusted as needed.
  • OCR for scanned PDFs – Scans and image PDFs recognized, converted, and prepared with AI assistance.
  • Standard PDF/UA Pipeline – Structure, tags, reading order, and alt text are prepared with AI assistance and presented for expert review in one pass.
02
PDFs are structured with AI assistance
Structure, tags, reading order, and alternative text are proposed with AI assistance – they are then reviewed and adjusted by people as needed.
03
Review the accessible document structure
Check reading order, headings, and alternative text directly in the browser and refine them as needed.
04
Every step is traceable
From AI-assisted remediation to validation — every step remains transparent and reviewable.
AI-assisted workflow
One workflow from upload to validation — with review and refinement before export.
Validated report
Validation results remain transparent, documented and easy to review.
Mandatory under the Accessibility Act

Accessible. Validated. Scalable.

Instead of manual rework, we automate exactly the steps that can be automated transparently – for PDF repositories of any size. People handle the rest: real accessibility does not come at the push of a button.

Background

Accessible documents are now legally required across Europe under the Accessibility Act (BaFG). Yet most PDFs today still aren't compliant – and in Austria alone, 1.3M+ people depend on accessible content. Manual remediation is expensive and doesn't scale.

The results

From upload to validated PDF/UA – AI-assisted processing with expert review to follow

PDF/UA, WCAG & EN 301 549 compliance with full quality report and audit log

Screen-reader compatibility checked, human-in-the-loop review as a fixed step – control and sign-off stay with domain experts
