Automated PDF Content Extraction and AI Processing Workflow

This n8n workflow is designed to automate the process of extracting content from a local PDF file, processing it through an AI language model, and saving the generated output back to the disk. It is particularly useful for automating content analysis, summarization, or data extraction from PDF documents without manual intervention.

The workflow begins with the Local File Trigger node, which initiates the process when a specified PDF file is updated or added to the local system. The ‘Read/Write Files from Disk’ node then reads the file contents, passing the data to the ‘Extract from File’ node, which extracts raw text or data from the PDF.

Next, the extracted content is sent to an AI Agent node, which integrates with a language model such as OpenAI’s ChatGPT. The AI processes the content—this could mean generating summaries, answering questions, or extracting key information. The ‘AI Agent’ node acts as the core processing engine.

The output from the AI is then converted into a file format using the ‘Convert to File’ node, preparing it for storage or further use. Finally, the processed file is saved back to the disk with the ‘Read/Write Files from Disk1’ node.

This workflow is valuable for automating document processing tasks like content summarization, data extraction from PDFs, or generating AI-driven insights from uploaded documents, streamlining workflows and reducing manual effort in document-heavy environments.
