Automated Multimodal Content Analysis with Google Gemini
detail.loadingPreview
This n8n workflow demonstrates the power of Google Gemini's multimodal capabilities by automatically fetching and analyzing content from images and PDFs. It efficiently converts various file types into a format consumable by Gemini, providing insightful descriptions and data extraction.
About This Workflow
This robust n8n workflow automates the analysis of diverse content types, including images from sources like Unsplash and PDF documents, leveraging the advanced multimodal capabilities of Google Gemini. It efficiently fetches these files, transforms their binary data into a Base64 format, and then intelligently dispatches them to the Gemini API for deep content understanding. The workflow also integrates n8n's AI Agent nodes, enabling more sophisticated processing and interpretation of the analytical results, making it ideal for automating content review, data extraction, and insightful reporting across various media formats, streamlining complex content workflows.
Key Features
- Multimodal AI Processing: Analyze both images (JPEG) and PDF documents using Google Gemini 2.0 Flash.
- Automated Content Ingestion: Fetch media files directly from URLs, including multiple images from sources like Unsplash.
- Binary Data Transformation: Seamlessly convert fetched binary files (images, PDFs) into Base64 for AI API compatibility.
- Google Gemini API Integration: Direct and secure calls to Gemini's
generateContentendpoint for comprehensive analysis. - AI Agent Orchestration: Utilize n8n's Langchain AI Agent nodes for enhanced decision-making and content interpretation based on Gemini's output.
How To Use
- Configure Google Gemini Credentials: Set up your Google Gemini (PaLM) API credentials and HTTP Query Authentication for the Gemini API calls. Replace placeholder credentials as needed to connect securely to your Google Cloud project.
- Adjust Content Sources: Modify the 'Get image from unsplash' and 'Get PDF file' nodes to point to your desired image or PDF URLs. You can also integrate other data sources like cloud storage or webhooks.
- Customize AI Prompts: Update the "text" parameter in the 'Call Gemini API' and 'AI Agent' nodes to specify the exact questions or analysis tasks you want Gemini to perform (e.g., "What's on this image?", "Summarize this PDF", "Extract all dates from this document").
- Run the Workflow: Click 'Test workflow' to initiate a manual run and observe the AI's content analysis in the output. Review the results to ensure they meet your analytical needs.
- Integrate with Other Services: Connect the output of the Gemini analysis nodes to other n8n nodes to automate follow-up actions, such as saving descriptions to a database, sending notifications via email/Slack, or updating content management systems.
