CommonLook PDF vs Nutrient DWS Accessibility API

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.

Nutrient DWS Accessibility API processes PDFs to add accessibility tags and check conformance. It returns a tagged PDF with PDF/UA metadata and targets PDF/UA-1 (ISO 14289-1). Tagging covers H1–H6 headings, ordered and unordered lists, table rows and cells, reading order, annotations and decorative artifacts. The API accepts HTTP requests from any programming language, with quickstarts for Java, C#, JavaScript, Python and PHP. Nutrient reports 96.5% PDF/UA conformance across a validation corpus of 3,157 files. Its free plan costs nothing and includes 20 auto-tagged pages and 100 validations per month. Starter costs $79 a month for 200 pages and 1,000 validations; Professional is $249 a month for 1,000 pages and 5,000 validations; Business is $499 a month for 3,000 pages and 15,000 validations. Monthly quotas do not roll over, and requests in a quota category are blocked when that quota runs out unless a larger plan or pay-as-you-go is used. Auto-tagging does not guarantee full accessibility compliance, so Nutrient recommends QA, especially for sensitive or high-stakes documents.
