Nutrient Document Processing (OpenClaw Native)

Best for OpenClaw users. Process documents directly in OpenClaw conversations — PDF conversion, text/table extraction, OCR, PII redaction, digital signatures, and watermarking via native nutrient_* tools.

Installation

Preferred install flow inside OpenClaw:

openclaw plugins install @nutrient-sdk/nutrient-openclaw

Configure your API key:

plugins:
  entries:
    nutrient-openclaw:
      config:

Data Handling

nutrient_* operations send the file or extracted document content to Nutrient DWS for processing.
Review Nutrient's Processor API security and privacy details before using production or sensitive documents.
Nutrient documents its hosted Processor API as using HTTPS for data in transit and as not persistently storing input or output files after processing; confirm that matches your organization's requirements before uploading sensitive material.
Start with non-sensitive sample files and a least-privilege API key.
