# Nutrient — Intelligent document platform for developers > Developer-first SDKs, cloud APIs, and low-code tools for building, processing, and automating document workflows. Our Web SDK (WASM) and Document Engine power high-fidelity viewing, editing, redaction, conversion, OCR, and AI-assisted tasks across web, mobile, and server environments. ## Key pages (start here) - [Web SDK (WASM) overview](https://www.nutrient.io/guides/web/) — Standalone, client-side PDF viewer/editor with annotations, forms, redaction, and more. - [Document Engine (self-hosted server)](https://www.nutrient.io/guides/document-engine/) — Headless PDF server for processing and streaming; integrates with Web SDK. - [.NET SDK — overview](https://www.nutrient.io/guides/dotnet/) — Comprehensive server-side document toolkit (conversion, OCR/KVP, redaction, signatures, forms, barcodes, imaging, scanning, compression). - Viewer option: [DocuVieware — HTML5 viewer for .NET](https://www.nutrient.io/sdk/dotnet/docuvieware/) - API reference: [GdPicture.NET API](https://www.nutrient.io/api/gdpicture/) - [Workflow Automation](https://www.nutrient.io/workflow-automation) — Low-code workflows for requests, approvals, compliance, and more. ## Web SDK (highest priority) - [Web SDK overview](https://www.nutrient.io/guides/web/) — WASM-based PDF rendering in the browser; no server required. - [Browser support and WASM](https://www.nutrient.io/guides/web/pspdfkit-for-web/browser-support/) — Rendering engine, compatibility, and performance notes. ## Interactive demos and Playground - [Web demos](https://www.nutrient.io/demo/viewer) — Interactive demo hub with 80+ live examples and code playground: viewer, annotations, forms, collaboration, signatures, editor, generation, conversion, redaction, OCR, security, comparison. ## Document Engine (with Web SDK) - [What is Document Engine?](https://www.nutrient.io/guides/document-engine/) — Self-hosted/headless service for processing and streaming (server-render → client bitmaps). - [Getting started](https://www.nutrient.io/sdk/document-engine/getting-started/) — Setup, deployment, and pairing with Web SDK. - [Downloads/Docker pull](https://www.nutrient.io/guides/document-engine/downloads/) — Pull from Docker Hub/AWS ECR. ## .NET SDK (server-side) and DocuVieware (viewer option) - **.NET SDK** — Broad capability set for enterprise-grade document workflows: - Conversion (HTML/Office/image↔PDF, PDF/A), merge/split, watermark, linearize - OCR and extraction (full/zonal), key-value pairs (KVP), tables, search - Redaction and security (programmatic/UI, encryption, digital signatures/certification) - Forms and annotations (create/fill/flatten, XFDF import/export, markup) - Imaging and compression (filters, deskew/denoise, MRC, barcode read/write) - Scanning and print (TWAIN/WIA capture, programmatic printing) - Links: [.NET guides](https://www.nutrient.io/guides/dotnet/), [GdPicture.NET API](https://www.nutrient.io/api/gdpicture/) - **DocuVieware (HTML5 viewer)** — Pairs with the .NET SDK for web apps (view, annotate, redact, sign, convert, collaborate). - Links: [overview](https://www.nutrient.io/sdk/dotnet/docuvieware/), [features](https://www.nutrient.io/sdk/dotnet/docuvieware/features/) ## Native SDKs - [iOS SDK](https://www.nutrient.io/sdk/ios/) - [Android SDK](https://www.nutrient.io/sdk/android/) - [React Native](https://www.nutrient.io/sdk/react-native/) - [Flutter](https://www.nutrient.io/sdk/flutter/) - [Node.js](https://www.nutrient.io/sdk/nodejs/) - [Salesforce](https://www.nutrient.io/low-code/integrations/salesforce) ## Integrations and Workflow - [Workflow Automation](https://www.nutrient.io/workflow-automation) — CAPEX, AP, purchase requests, travel, contract approval, etc. - [Document Converter (Muhimbi)](https://www.nutrient.io/low-code/document-converter) — 100+ conversions, merge, watermark, OCR (KVP). - [Document Editor](https://www.nutrient.io/low-code/document-editor) - [Searchability (OCR)](https://www.nutrient.io/low-code/document-searchability) ## AI and authoring - [AI document processing](https://www.nutrient.io/sdk/ai-document-processing/) — Intelligent document processing for classification and data extraction (KVP, tables) across PDFs and images. Implementation: [developer guides](https://www.nutrient.io/guides/ai-document-processing/intro/). - AI APIs: [data extraction](https://www.nutrient.io/api/data-extraction-api/), [AI redaction](https://www.nutrient.io/api/ai-redaction-api/), [OCR](https://www.nutrient.io/api/pdf-ocr-api/). - [AI Assistant](https://www.nutrient.io/sdk/ai-assistant/) — Chat, summarize, translate, and redact inside the viewer UI; works with your model provider. Implementation: [guides](https://www.nutrient.io/guides/ai-assistant/). - [Document Authoring SDK](https://www.nutrient.io/sdk/document-authoring/) — WYSIWYG DOCX editor with PDF-fidelity export. Implementation: [guides](https://www.nutrient.io/guides/document-authoring/). ## Use and licensing (summary) - Commercial/closed source; licensed per bundle ID (iOS), package name (Android/Windows), or domain (Web). - Web SDK runs client-side (WASM). Document Engine is self-hosted or managed. - .NET offers comprehensive server-side processing; DocuVieware is the HTML5 viewer. ## Contact - Email: support@nutrient.io - Security: https://www.nutrient.io/security/ - Partners: https://www.nutrient.io/partners/ - Customers/Stories: https://www.nutrient.io/blog/categories/customer-stories/ ## Optional Use these links to access deep-dive indexes for platform-specific guides, API reference, and blog content: ### SDKs - [Web SDK](https://www.nutrient.io/guides/web/llms.txt) — JavaScript/WASM PDF SDK - [.NET SDK](https://www.nutrient.io/guides/dotnet/llms.txt) — Server-side document processing - [iOS SDK](https://www.nutrient.io/guides/ios/llms.txt) — Swift/Objective-C mobile SDK - [Android SDK](https://www.nutrient.io/guides/android/llms.txt) — Kotlin/Java mobile SDK - [Java SDK](https://www.nutrient.io/guides/java/llms.txt) — Server-side Java SDK - [Node.js](https://www.nutrient.io/guides/nodejs/llms.txt) — Node.js integration - [Flutter](https://www.nutrient.io/guides/flutter/llms.txt) — Cross-platform mobile SDK - [React Native](https://www.nutrient.io/guides/react-native/llms.txt) — Cross-platform mobile SDK - [.NET MAUI](https://www.nutrient.io/guides/maui/llms.txt) — Cross-platform .NET SDK ### Server and Cloud - [Document Engine](https://www.nutrient.io/guides/document-engine/llms.txt) — Self-hosted PDF processing server - [DWS Processor](https://www.nutrient.io/guides/dws-processor/llms.txt) — Cloud document processing API - [DWS Viewer](https://www.nutrient.io/guides/dws-viewer/llms.txt) — Cloud document viewing API ### AI features - [AI document processing](https://www.nutrient.io/guides/ai-document-processing/llms.txt) — Intelligent document extraction - [AI Assistant](https://www.nutrient.io/guides/ai-assistant/llms.txt) — AI-powered document assistant - [Document Authoring](https://www.nutrient.io/guides/document-authoring/llms.txt) — Document creation and editing ### API reference - [Web SDK API](https://www.nutrient.io/api/web/llms.txt) — JavaScript/TypeScript API reference - [iOS SDK API](https://www.nutrient.io/api/ios/llms.txt) — Swift/Objective-C API reference - [Android SDK API](https://www.nutrient.io/api/android/llms.txt) — Kotlin/Java API reference - [Java SDK API](https://www.nutrient.io/api/java-sdk/llms.txt) — Server-side Java API reference - [React Native API](https://www.nutrient.io/api/react-native/llms.txt) — Cross-platform mobile API reference - [.NET MAUI API](https://www.nutrient.io/api/maui/llms.txt) — Cross-platform .NET API reference - [GdPicture.NET API](https://www.nutrient.io/api/gdpicture/llms.txt) — .NET document processing API reference - [DocuVieware API](https://www.nutrient.io/api/docuvieware/llms.txt) — HTML5 viewer API reference - [AI Assistant API](https://www.nutrient.io/api/ai-assistant/llms.txt) — AI-powered document assistant API reference - [Document Authoring API](https://www.nutrient.io/api/document-authoring/llms.txt) — Document editor API reference - [XtractFlow API](https://www.nutrient.io/api/xtractflow/llms.txt) — AI document processing API reference ### Blog - [Nutrient blog](https://www.nutrient.io/blog/llms.txt) — 1,900+ articles on document technology, SDKs, and workflow automation
