AI agents are revolutionizing how cities work around the world. Cities are using smart computer programs called AI agents that automatically help people solve problems and make better decisions about city planning. In Bangkok, Thailand, a system called Traffy Fondue lets people report problems like broken streetlights through their phones. The AI agent automatically reads these reports and sends them to the right city department to fix them. By mid-2025, this smart system handled nearly one million citizen reports. In Singapore, a chatbot named Moments of Life helps new parents get services they need. Instead of filling out 120 minutes of paperwork, parents now finish everything in just 15 minutes. In Buenos Aires, Argentina, a WhatsApp chatbot called Boti helps residents ask questions and report issues through the messaging app they use every day.

These AI agents are also helping cities plan for the future. Singapore built a Digital Urban Climate Twin that uses real data to predict how hot different neighborhoods will get and helps city leaders make smart decisions about trees and cool roads. Sydney, Australia created a digital twin that predicts where car accidents might happen on specific roads, so city planners can decide where to add bike lanes or change speed limits before people get hurt. Barcelona, Spain treats its city data like a public treasure and uses open-source computer programs to keep companies from locking them into expensive deals. These AI agents and smart planning tools are spreading because they help cities give better services to residents while using less money and resources.
