The Chicago Data Portal provides public access to over 600 machine-readable datasets, driving transparency and civic innovation since its 2012 launch.

This is Chicago’s central hub for open government data: a free, powerful resource mandated by a 2012 executive order. The portal hosts over 600 datasets, with many updated daily, covering everything from 311 Service Requests (like rodent baiting) to crime statistics dating back to 2001. Users can access data on Current Employee Salaries, Uber/Lyft trips, and building permits. Data is provided in both human-readable formats and via API (Socrata’s SODA), enabling developers, journalists, and residents to create custom applications and perform deep analysis.

## Recent Public Talks and Demos

### [From Open Data Portal to Real-Time Alerts: Building an AI-Driven Tow Warning System](https://chicago.aitinkerers.org/talks/rsvp_gwiaSHSKNRc)

I’ll demo a system I built at a civic tech hackathon that automatically monitors city tow data and sends real-time alerts to car owners when their vehicles are impounded. The talk will focus on the technical pipeline: data ingestion from civic sources, automation workflows, alert triggering, and the big secret for engineers looking to make something valuable.

### [Building Municipal AI: Natural Language Interfaces for Public Data and Legal Code](https://chicago.aitinkerers.org/talks/rsvp_B3k-2rmF91I)

Take a deep dive into Municodex, an AI system that translates natural language queries into actionable insights from Chicago's Data Portal and Municipal Code. This hands-on demo will apply a combination of vector search, prompt engineering, and API orchestration to create meaningful AI interfaces (agents) for public data. We will walk through live examples, explain how it works, and time permitting dive into the code that powers seamless data retrieval and intelligent text generation. Whether you're looking to build similar applications or enhance your AI projects with data-driven insights, Municodex offers both inspiration and practical knowledge to elevate your AI endeavors.
