• Document Upload: PDF files are automatically uploaded to LlamaIndex Cloud for processing
• Smart Status Monitoring: The system continuously checks processing status and adapts the workflow based on results
• Conditional Content Extraction: Upon successful processing, extracted Markdown content is retrieved for further use
