Semantic QA

Not only PDF/UA-compliant. Also semantically checked.

barrierefrAI does not only generate formally valid PDF/UA files. The processing also checks whether the accessible structure matches the visible document: reading order, tables, lists, links, image content and complex layouts.

Reading order

Multi-column documents, legal sub-items and visible reading sequences are checked for plausibility.

Tables & pseudo-tables

Real data tables, table-like layouts and tables embedded as raster images are handled differently.

Links, QR codes, status

Visible URLs, QR context, checkboxes, status chips and form-like areas remain understandable.

Beyond PAC

Technical validation is complemented by semantic stress tests that expose typical AI remediation errors.

Tested on complex real-world documents, including multi-column insurance conditions with a table of contents, tables, lists, exclusions, references and a glossary.
