Nutrient AI Assistant

In-viewer document-AI feature for Nutrient client SDKs (Web, iOS, Android, React Native) backed by a Docker service. Users chat with the open document for Q&A, summarisation, translation, redaction, and form filling; from Q1 2026 onward an agents layer plans and executes multi-step edits autonomously under policy-defined approval gates.

Documentation

Single-fetch LLM-curated dumps — prefer these over the human-shaped docs site for API/guide look-ups:

• API reference: https://www.nutrient.io/api/ai-assistant/llms.txt
• Guides: https://www.nutrient.io/guides/ai-assistant/llms.txt
• Cross-product index (other Nutrient SDKs): https://www.nutrient.io/llms.txt

Key Concepts

• Architecture: a Docker container (pspdfkit/ai-assistant, also at public.ecr.aws/pspdfkit/ai-assistant) plus a PostgreSQL database with the pgvector extension, plus credentials for an LLM provider (OpenAI / Azure OpenAI / AWS Bedrock / self-hosted OpenAI-compatible). The legacy pspdfkit/ai-document-assistant image is the pre-rebrand name; new deployments use pspdfkit/ai-assistant.
• Client integration: existing Nutrient SDKs (Web / iOS / Android / React Native) — nothing extra to install; configure an aiAssistant block (Web) or an AIAssistantConfiguration on PDFConfiguration (iOS / Android / React Native), and add the ai-assistant toolbar item (Web) or aiAssistantButtonItem (mobile).
• Current names: toolbar item ai-assistant; Web config block aiAssistant. The legacy ai-document-assistant / aiDocumentAssistant keys predate the rebrand — current docs and examples use the new names.
• Required env vars on the backend: ACTIVATION_KEY, API_AUTH_TOKEN, JWT_PUBLIC_KEY, plus one LLM-provider credential (OPENAI_API_KEY / AZURE_API_KEY / BEDROCK_ACCESS_KEY_ID+BEDROCK_SECRET_ACCESS_KEY).
• Two-JWT pattern: when the client SDK is paired with Nutrient Document Engine, the browser sends one JWT to the engine (authPayload.jwt) and a different JWT to AI Assistant (aiAssistant.jwt). They're signed with different keys, scoped differently, and shouldn't be reused.
• Standalone vs paired: AI Assistant does not require Nutrient Document Engine. Standalone (WASM-only Web SDK) and paired (server-backed against Document Engine for collaborative storage, Nutrient Instant) are both first-class.
