Benchmark Results
Independent benchmark results
We tested identical document sets across all four remediation approaches. Able Layer achieves best-in-class scores across every dimension.
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.

Navigation Efficiency
Average 3.2 tab stops to reach content in Able Layer-remediated documents, compared to the industry average of 12.4 tab stops. That's a 74% reduction in navigation effort for keyboard and screen reader users.

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.
