Describe all images in a PDF

Description

AI-powered workflow for end-to-end image extraction and intelligent analysis directly from PDF documents

📄 Manually capturing images from PDFs and sending them to AI for analysis is slow and tedious. This workflow automates the entire process — from image extraction to GPT-4o-based interpretation — delivering fast, reliable insights with zero manual effort.

🧠 What Problem Does It Solve?
Traditional image extraction from PDFs involves screenshots, manual uploads, and copy-pasting AI insights into a separate document. This workflow eliminates those steps, saving time and reducing human error by automating both image handling and analysis.

🚀 It automatically processes entire PDF files to:

✅ Extract embedded images
✅ Send them to GPT-4o for rich, contextual analysis
✅ Combine the results into a clean, downloadable .txt report

⚙️ How It Works
📥 Uploads a PDF from Google Drive
🖼 Converts PDF pages into image files using ConvertAPI
🔎 Extracts individual image URLs from the PDF
🤖 Sends each image to GPT-4o for AI-driven analysis
🧾 Merges all image URLs and AI insights
📝 Outputs everything into a formatted .txt file

✨ Key Features
🔁 Fully automated — no manual screenshots needed
🔬 Uses GPT-4o for deep image analysis
🗂 Organizes results by image with URLs + GPT summary
📤 Export-ready: .txt file with analysis included
⚙️ Works with any image-rich PDF
🧰 Customizable for various platforms (Slack, Telegram, etc.)

🛠 Setup Instructions

1. Connect your Google Drive, ConvertAPI, and OpenAI (GPT-4o) credentials

2. Upload your image-heavy PDF to Google Drive

3. Trigger the workflow manually or via automation

4. Wait as it extracts images and processes them

5. Download the .txt file with all results

💡 Tip: ConvertAPI occasionally returns 503 errors — retry after a short delay.

🔧 How to Customize

• Swap the manual trigger for a Google Drive auto-trigger

• Replace GPT-4o with another model if needed

• Output the results to chat apps, databases, or custom dashboards

• Apply this template to PDFs with infographics, charts, scans, or reports
