Flood-Gentic Is an AI-powered flood preparedness and response assistant for Metro Manila, helping residents find evacuation centers, check local flood risk and weather, get emergency contacts, avoid flooded routes, and access practical safety guidance in English or Filipino. It combines official information and community reports, with a safety-first approach: emergencies get an immediate fixed 911 response, and the assistant avoids guessing when reliable data is unavailable. Highlights: Hybrid RAG: The document assistant combines semantic vector search with BM25 keyword search, then merges results using Reciprocal Rank Fusion. It uses FAISS and Supabase pgvector to retrieve information from preparedness and other source documents. 15 specialist AI Agent response paths: Emergency guidance, reports, routes, evacuation, contacts, location, flood risk, weather, document search, and flood-photo checks. Most use deterministic rules or verified data; only selected answers use a chat model. Photo and voice input: Residents can ask questions about flood photos, with SAM 3.1 used for flood-water analysis, person segmentation or speak their question for live transcription. Glass-inspired interface: The frontend has translucent panels and a slider for adjusting their frosted-glass appearance. This is a visual UI treatment - for futuristic VR headset or smart-glasses integration. More than chat: The app also offers flood and weather dashboards, evacuation-center and contact listings, weather analytics, community reporting, and staff tools for reviewing reports and assistance requests.
