AI Media Analysis Workflow with n8n and Google Gemini

This workflow demonstrates multiple methods to analyze various media types—images and PDFs—using n8n integrated with Google Gemini’s AI models. Triggered manually with a ‘Test workflow’ button, it showcases five different approaches: 1) Quick analysis of a single image, 2) Customized analysis for multiple images, 3) Standard item processing with direct API calls for multiple images, 4) PDF content analysis, and 5) Image analysis with advanced control. The workflow fetches images from Unsplash, transforms media into base64 format, and sends them to Gemini for descriptive insights. It also retrieves a sample PDF for content understanding. Practical scenarios include media content description, visual data summarization, and document analysis to enhance digital content management, user engagement, or automated content tagging.
