Overview

The way people use AI has fundamentally changed. What was once a simple back-and-forth with a chatbot has evolved into a grand variety of autonomous agents capable of executing complex, multi-step workflows. Drawing on Ethan Mollick's guide on Agentic AI, this course breaks down the three elements you need to understand to choose the right AI setup: models (the underlying intelligence), apps (the interfaces you interact with), and harnesses (the systems that let AI use tools and take real action). You'll learn the practical differences between leading platforms from OpenAI, Anthropic, and Google: not just which models are "smartest," but which apps and harnesses actually deliver results for research, coding, data analysis, and document work. Through hands-on demonstrations, you'll see tools like Claude Code, Claude Cowork, and NotebookLM in action, and learn how to transition from prompting AI to managing it as a capable digital worker.
