House Calls is a Chicago-based house music event brand known for exclusive parties and a mysterious host named Stella. To extend the brand’s identity and create a more interactive fan experience, I built a real-time AI version of Stella that attendees could call and talk to directly. The AI concierge answered questions about upcoming events, shared details about the House Calls community, and even revealed secret event locations for select parties.
