BahaBantay ("flood watch") turns messy Filipino flood reports into a clear next step for residents and a verified, ranked action queue for barangay responders. The Philippines gets about 20 typhoons a year, and during floods "baha na dito!" posts end up scattered across chats, so people end up guessing which roads are passable and who needs help first. Residents send a 3-step report (photo, street, water level). Meta SAM 3.1 estimates the water depth from the photo, and Muse Spark reads Filipino, English or Taglish notes for hazards and people at risk. The reporter confirms or corrects the Al's suggestion before anything is published. Reports add up into 250 m confidence cells across all 42,010 PSGC barangays, with time-decay (a report's weight halves every hour and it expires after 6 h), per-browser dedupe and community "still flooded / already clear" votes. The emergency-first Home tab shows a barangay alert, Get help with 911 and hotlines, and EN/ FIL and dark mode. The Responder tab ranks incidents with their evidence and drafts bilingual advisories plus a 160-character SMS. Fixed safety rules stop the app from ever calling an area "safe" from one photo or marking anything as verified from AI alone.
