PDFAccessibility.ai combines PDF accessibility checks, remediation, manual editing, accessible PDF export, and a structured-data API. Its checks report issues against WCAG, PDF/UA, Section 508, ADA, and EN 301 549 expectations. The remediation workflow tags document structure, improves reading order, and detects headings and tables to prepare files for assistive technology. Users can edit tag types, heading levels, content, and image alt text when automation flags complex items. Batch workflows provide per-file actions and ZIP downloads. The Smart PDF RAG API returns JSON and Markdown with typed elements, tables, reading order, page references, and bounding boxes; documented API processing uses asynchronous uploads and polling. The free PDF Accessibility plan includes 10 accessible exports, unlimited checks, and seven-day file retention. Paid plans start at $29.00 USD per month. The privacy policy says uploads are not used to train public AI models, though some workflows may send necessary information to infrastructure or AI providers. Complex layouts, unusual tables, scanned pages, or ambiguous reading order may need manual review.

The record

What it does

The platform combines PDF accessibility checking, remediation, manual editing, accessible PDF export, and a Smart PDF RAG API.

Accessibility checks

It reports issues against WCAG, PDF/UA, Section 508, ADA, and EN 301 549 expectations.

Automatic remediation

The remediation workflow tags PDF structure, improves reading order, detects headings and tables, and prepares documents for assistive technology.

Manual editing

Users can review and edit tag types, heading levels, content, and image alt text when automation flags complex items.

Batch workflows

Batch remediation supports per-file actions and ZIP downloads of ready accessible PDFs.

RAG output

The API returns structured JSON and Markdown with typed elements, tables, reading order, page references, and bounding boxes.

API integration

The documented API accepts PDF uploads at an asynchronous parse endpoint and uses polling for completed output.

API key handling

The docs advise keeping API keys server-side and sending them in an X-API-Key header.

API limitation

The API documentation identifies polling as the current baseline and says not to design around webhook delivery unless a supported integration is enabled.

Security and privacy

The privacy policy says uploaded documents are not used to train public AI models and describes administrative, technical, and organizational safeguards.

Data processing

Some workflows may send necessary information to infrastructure or AI providers for document analysis, accessible text generation, or document intelligence.

Retention limit

The free PDF Accessibility plan retains files for 7 days; the policy says retention can vary by plan, workflow, workspace configuration, and operational needs.

Accuracy and review

The FAQ describes automatic remediation as about 90% accurate across common PDFs and says complex layouts, unusual tables, scanned pages, or ambiguous reading order may need manual review.

Intended users

The pricing page identifies compliance teams, agencies, education, government, legal, and healthcare teams as users for PDF remediation, and developers and AI teams for structured PDF data.
