Key capabilities include viewing, rendering, annotations, real-time collaboration, form handling, digital/electronic signatures, editing, redaction, OCR, and AI-powered features. 2. **Document Engine** — A self-hosted PDF server for processing documents and powering server-side automation workflows. It operates standalone or as a backend for the SDKs for enhanced performance and collaboration. 3. **Document Web Services (DWS)** — Fully managed, SOC 2 Type 2-audited cloud APIs for high-scale document viewing and processing. Includes DWS Viewer API (for cloud-based rendering), DWS Processor API (30+ action-based APIs for generation, conversion, watermarking, merging, and much more), and DWS Accessibility API (for PDF accessibility remediation). 4. **Workflow Automation platform** — A no-code/low-code SaaS platform to automate business processes centered around documents, forms, and approvals. Features include a process builder, form designer, approval routing, and intelligent document processing with AI. 5. **Low-Code integrations (M365 and Salesforce)** — Advanced document functionality embedded directly into platforms such as Microsoft 365 (SharePoint, Power Automate) and Salesforce. Capabilities include conversion, OCR, watermarking, PDF form handling, and native generation/editing, without requiring plugins or custom code. ## Key differentiators - **Full document lifecycle** — End-to-end capabilities in one platform. - **Developer flexibility** — Clean APIs, extensive customization, and deployment flexibility (cloud, self-hosted, air-gapped). - **AI-native** — Intelligence is embedded across all products for agentic workflows and document intelligence. - **Enterprise trust** — SOC 2 Type 2 audited and WCAG compliant, deployed in regulated industries. ## Primary use cases - Accessibility remediation for large existing PDF libraries. - PDF/UA auto-tagging in document processing pipelines. - Prepublication QA workflows for compliance-sensitive documents. - Standardizing semantic structure before downstream validation and review. ## DWS Accessibility API Nutrient DWS Accessibility API is an HTTP API for accessibility remediation workflows. It helps teams auto-tag PDFs with semantic structure so assistive technologies can interpret document content more reliably. ### Key capabilities - **Auto-tagging for PDF/UA workflows** — Detects structural elements and writes semantic tags into the PDF structure tree. - **Reading-order normalization** — Improves logical reading sequence for assistive technology users. - **Remediation pipeline integration** — Supports document-in, document-out processing through authenticated HTTP requests. - **Scalable operations** — Supports high-volume remediation workflows with quota-based plans. ## API reference API documentation is available at https://www.nutrient.io/api/reference/public/. ## Documentation directory [Accessibility best practices](https://www.nutrient.io/guides/dws-accessibility/developer-guides/accessibility-best-practices/): Practical guidance for producing accessible PDFs in real-world remediation workflows.
