Problem Solved

This workflow addresses the challenge of manually extracting images from PDF files and analyzing them using AI. It automates the entire process, saving time and reducing human error. Users can quickly retrieve insights from images without the need for extensive manual intervention.

Workflow Steps

  • Manual Trigger: The workflow starts when the user clicks the ‘Test workflow’ button.
    2. Get PDF File: The specified PDF file is downloaded from Google Drive.
    3. Extract Images: The workflow sends a request to Convert API to extract images from the PDF.
    4. Get Image Data: The extracted images are split for further processing.
    5. Get Image URLs: The URLs of the extracted images are collected for analysis.
    6. Analyze Images: Each image is analyzed using the GPT-4o model, generating detailed insights.
    7. Compile Analysis: The results from the image analysis are compiled along with their corresponding URLs.
    8. Integrate Content: All the analysis results are merged into a single content string.
    9. Output to Text File: Finally, the compiled content is saved as a .txt file for easy access and sharing.

    • Customization Guide

    Users can customize this workflow by:
    - Modifying API Credentials: Update the credentials for OpenAI, Convert API, and Google Drive to use their own accounts.
    - Changing Input PDF: Replace the PDF file ID in the Get pdf file node to analyze different documents.
    - Adjusting Analysis Parameters: Modify the text prompt in the Analyze image node to tailor the analysis according to specific needs.
    - Adding Additional Nodes: Users can insert more nodes for additional processing, such as sending notifications or integrating with other applications.
    - Changing Output Format: Modify the Output content to a .txt file node to change the format or location of the output file.
