Classify Event Attendee Photos with Gemma AI, Drive & Sheets

This n8n workflow streamlines event photo management by providing a shareable form for attendees to upload photos directly from their devices. It splits the process into two branches: one optimizes images for cost-effective AI processing and classifies them using Gemma AI via Featherless.ai's unlimited token subscription, categorizing against predefined tags; the other copies originals to Google Drive for archiving.

Results from both branches merge to append classification details, Google Drive links, and metadata to a Google Sheets spreadsheet, enabling easy sorting, filtering, and analysis. This eliminates manual categorization, reduces processing time from hours to minutes, and caps AI costs predictably.

Ideal for event organizers, conferences, or workshops with high photo volumes. Benefits include scalable handling of attendee submissions, professional organization without custom apps, and integration with familiar Google tools. Use cases: corporate events, weddings, trade shows, or any scenario needing quick photo tagging and retrieval.
