Nutrient (formerly PSPDFKit)

Nutrient (formerly PSPDFKit) is a cloud-based and self-managed PDF Editors and document processing platform designed for software developers, enterprise IT teams, and application architects. Following a 2024 corporate rebranding that unified PSPDFKit alongside acquired technologies (including Muhimbi, ORPALIS, Aquaforest, and Integrify), Nutrient provides a suite of Software Development Kits (SDKs), hosted APIs, Model Context Protocol (MCP) server connections, and workflow automation tools to embed document viewing, editing, annotation, conversion, optical character recognition (OCR), data extraction, and electronic signatures directly into web, mobile, and server applications.

Embedded SDKs & Self-Managed Document Engine

Nutrient offers client-side and server-side SDKs supporting WebAssembly, browser, mobile (iOS and Android), and desktop environments. Its self-managed Document Engine deploys on-premises or via Docker containers within air-gapped infrastructure, allowing enterprise applications to render, edit, annotate, compare, and digitally sign PDF, Microsoft Office, and image files without transmitting document content to third-party cloud hosts.

Intelligent Data Extraction & Source Grounding

Through its Data Extraction API and machine learning models, Nutrient extracts structured text, tabular data, key-value pairs, and form fields from scanned documents, invoices, and unstructured PDF files. Extracted values carry source citations, match labels, and confidence signals, allowing developers to build verification interfaces where users can inspect source evidence alongside extracted data fields.

Agentic Document Authoring & MCP Server Connections

Nutrient includes Document Authoring tools and native MCP server interfaces that allow artificial intelligence (AI) agents to read, revise, compare, redact, and export documents. To prevent unauthorized or invalid document modifications by autonomous agents, the platform enforces pre-edit argument validation and target checks, giving applications policy-based control over which edits apply automatically and which require human review.

Document Generation, Conversion, & Workflow Automation

The platform provides hosted Document Services APIs and low-code connectors for Microsoft 365, SharePoint, Salesforce, ServiceNow, HubSpot, and Nintex. Organizations can build automated Business Process Automation pipelines that generate PDF documents from HTML templates or database records, convert Office files, apply redaction rules to sensitive text, and route documents through multi-step approval and eSignature workflows.

Enterprise Deployment & Compliance

Nutrient is audited under SOC 2 Type II controls and maintains compliance with General Data Protection Regulation (GDPR) and Cloud Security Alliance (CSA) standards. The vendor states that over 3,000 organizations and 15 percent of Global 500 companies deploy Nutrient software across hosted US and EU cloud regions, processing more than one billion document interactions annually.
