Earlier today, Google debuted Gemini 2.0. The company says its new machine learning model won't just enhance its existing products and services. It will also power entirely new experiences. To that point, Google previewed Project Mariner, an AI agent that can navigate within a web browser. Mariner is an experimental Chrome extension that is currently available to select "trusted testers."
