The extracted text is stored in your output variable:

{{document_content}}

Differences from OCR Node

Best Practices

• Use for digital documents with embedded text
• For scanned documents or images, use the OCR node instead
• Handle large documents by chunking if needed
• Combine with LLM nodes for document analysis
