Ethni-CITY: The New Travel App

Ethni-CITY is a travel app that analyzes uploaded photos using Gemini 3.1 Pro to identify locations via landmarks and cultural motifs, then connects travelers' social media posts with local artists' music to help monetize their craft. The app uses Cesium JS with Google Cloud photorealistic tiles for immersive storytelling and implements a three-tier Gemini model fallback system for resilience.
