Benchmark conducted on identical 1,000-document corpus. Full-service firm times represent manual remediation workflows. All scores independently verified.

Methodology

How we test

Our benchmark methodology is designed to be reproducible, comprehensive, and aligned with real-world accessibility auditing standards.

Test Corpus

47,000 PDFs sourced from 12 industries: higher education, government, healthcare, finance, legal, insurance, manufacturing, K-12, nonprofit, energy, retail, and real estate.

Validation Pipeline

Every document passes through veraPDF for PDF/UA-2 conformance, axe-core for WCAG 2.2 AA compliance, and a manual audit sampling protocol with inter-rater reliability of 0.94.

Scoring Model

A 7-dimensional weighted loss function evaluates technical validation, content fidelity, reading order, heading hierarchy, table structure, alt text quality, and navigation efficiency.

Document Handling

Built for complexity

Most tools break on anything beyond simple text. Able Layer handles the documents other platforms reject.

Assistive Technology

Real screen reader testing, not just tag checking

Compliance tags alone don't guarantee usability. We test every remediated document with actual screen readers to verify the experience is correct.

Audit Trail

Every remediation is fully auditable

Complete transparency at every step. When auditors or legal teams ask "what did you do and how?" — you have a definitive answer.

Before / After Comparison

Every remediation includes a side-by-side diff showing exactly what changed: tag structure, reading order, alt text, heading hierarchy, and table relationships.

Detailed Change Log

A machine-readable JSONL audit log records every patch applied by the repair crew, including the rationale, affected elements, and validation results for each change.

Compliance Certificate

Every completed remediation includes a veraPDF validation report confirming PDF/UA-2 conformance and a signed compliance certificate with document hash verification.

Executive Report

A PDF executive summary with WCAG 2.2 AA breakdown, before/after scores, issue categories, remediation actions taken, and time-to-compliance metrics.
