Summarize Docs, Images & Spreadsheets with Gemma 3 on Ollama

This n8n workflow revolutionizes file management by automatically detecting and analyzing files dropped into a monitored folder. Powered by Ollama's Gemma 3 model running locally, it handles diverse formats: visual descriptions for images, text extraction and summarization for PDFs, and structural insights for spreadsheets like CSVs and XLS. No cloud dependency ensures privacy and speed.

Key benefits include instant AI-driven insights without manual effort, multi-format support saving hours on analysis, and organized outputs as named text files. It's ideal for researchers, analysts, or anyone dealing with mixed media files, enhancing productivity in content review, data auditing, or quick overviews.

Use cases span document-heavy workflows: summarize reports from conferences, analyze travel photos for key elements (despite category), or extract trends from expense spreadsheets. Prerequisites: Install Ollama, pull Gemma 3:4b model, run the service. Setup: Clone workflow, set folder path in Local File Trigger, configure credentials, and test with sample files.
