## Product suite

Nutrient’s interconnected product lines include:

1. **SDKs** — Developer-first, cross-platform development kits for embedding PDF functionality into native and hybrid applications (Web, iOS, Android, React Native, Flutter, and many more). Key capabilities: 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 the DWS Viewer API (for cloud-based rendering) and DWS Processor API (30+ action-based APIs for generation, conversion, watermarking, merging, and much more).
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. **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
