CommonLook PDF vs PDFAccessibility.ai

CommonLook PDF helps organizations remediate PDFs for accessibility and compliance. Users can choose an advanced or simplified editor based on their experience and document complexity. AI-driven tagging assists with tables, lists, forms, and other elements, while manual tagging tools and a Fix Wizard support review and correction. The software provides PDF tagging, reading-order, and alternative-text tools, and validates against WCAG, PDF/UA, and HHS standards. It can generate bookmarks from document headings and supply a downloadable Validation Report showing passed, failed, and warning issues. A system of record tracks remediation history and lets users remove older files or download accessible PDFs with their reports. The desktop version is an on-premises plugin for Adobe Acrobat Pro or Pro DC. Allyant offers live and on-demand training and a CommonLook Knowledge Base. The product is designed for users of every ability and organizations addressing requirements such as Section 508, ADA Title II, and the EAA. Pricing is available on request, and a seven-day trial is listed.

PDFAccessibility.ai combines PDF accessibility checks, automated remediation, manual editing, accessible export, and an API for structured PDF data. Its checks report issues against WCAG, PDF/UA, Section 508, ADA, and EN 301 549 expectations. Remediation can tag document structure, adjust reading order, and detect headings and tables. Users can review tags, heading levels, text, and image alt text when automation flags complex items. Batch workflows support file-specific actions and ZIP downloads. The Smart PDF RAG API returns JSON and Markdown with typed elements, tables, reading order, page references, and bounding boxes; its documented workflow uses asynchronous uploads followed by polling. API guidance recommends keeping keys server-side and sending them in an X-API-Key header. The free PDF Accessibility plan includes 10 accessible exports and retains files for seven days. Paid plans start at $29 a month. The privacy policy says uploads are not used to train public AI models, while noting that some processing may send necessary information to infrastructure or AI providers. Complex layouts and other difficult PDFs may need manual review.
