## Two-phase remediation

Structural fixes happen instantly at zero cost. AI-powered semantic tagging adds deep accessibility when you need it.

### 01 Structural Remediation

**Instant, zero AI cost**

- Sets PDF metadata — title, language, creator, dates
- Marks document as tagged (MarkInfo.Marked = true)
- Adds PDF/UA-1 identifier in XMP metadata
- Sets tab order to structure order on all pages
- Creates complete structure tree with role mapping
- Creates parent tree for reverse structure lookups
- Ensures page resources exist for every page
- Generates bookmarks from document structure

**<2s processing time per document**  
**$0 AI cost — all local processing**

### 02 AI Content Tagging

**Deep semantic accessibility**

- Parses PDF content streams (BT/ET operators, text positioning)
- AI semantic analysis identifies headings, paragraphs, lists, tables
- Injects marked content (MCID tags) into content streams
- Builds full semantic structure tree
- AI-generated alt text for images (GPT-4o with Claude fallback)
- Color contrast analysis with WCAG luminance ratios

**30–60s processing time per document**  
**$2 per page — includes all structural fixes**

## Four standards, one API

Every remediated document targets compliance across all major accessibility standards simultaneously.

### WCAG 2.2 AA

The latest Web Content Accessibility Guidelines. Level AA conformance ensures content is perceivable, operable, understandable, and robust for users with disabilities.

### PDF/UA-1

ISO 14289-1 standard for universally accessible PDF documents. Structure trees, tag mappings, and metadata that assistive technologies rely on.

### Section 508

Federal mandate requiring electronic documents be accessible to people with disabilities. Required for all U.S. government agencies and contractors.

### ADA Compliance

Americans with Disabilities Act requires accessible communication. PDF remediation ensures documents meet digital accessibility requirements.
