Overview

End-to-end production platform making government documents accessible for residents who use screen readers and assistive technology. Converts PDFs to WCAG 2.1 AA-compliant HTML in 30–90 seconds (vs. 1–4 hours of manual specialist work). Excel budget exports process in under 1 second with perfect accuracy. Five-layer validation pipeline: axe-core accessibility checks (80+ WCAG rules), numeric integrity verification (every dollar amount and date cross-checked), completeness validation (every section and heading confirmed), quality scoring (0–100, below 90 flagged), and mandatory human review with side-by-side comparison. All processing runs within county Google Cloud infrastructure — zero data leaves the environment. Deployed for Multnomah County to meet the April 2026 federal ADA compliance deadline across thousands of public documents.

Validation Pipeline

1

Accessibility compliance

axe-core runs 80+ WCAG 2.1 AA checks (heading structure, color contrast, table markup, image descriptions, screen reader compatibility)

2

Numeric integrity

every number, dollar amount, percentage, and date cross-checked against the original document

3

Completeness

every section, heading, and content block verified to exist in the output

4

Quality scoring

overall score 0–100 based on WCAG compliance, content integrity, and structural accuracy; below 90 gets flagged

5

Human review

reviewer compares original and output side by side, then approves or rejects; feedback improves future conversions
