Google Antigravity First Look: The New "Agentic" AI Editor from Google

In this video, I take a first look at Google's brand new AI-powered IDE, Antigravity. Powered by the new Gemini 3 Pro model, this editor claims to be the next generation of "Agentic" coding tools, competing directly with Cursor and Windsurf. I walk you through the entire process—from downloading and installing Antigravity on macOS to building a fully responsive React portfolio website from scratch. We test out its unique "Planning Mode" vs. "Fast Execution," check its ability to fix bugs autonomously, and see if it can handle complex tasks like adding a dark mode toggle and mobile responsiveness In this video, we cover: - How to download and install Google Antigravity - The difference between "Planning" and "Fast" modes - Building a React Portfolio using Gemini 3 High - Testing the AI's ability to self-correct errors - Is it better than VS Code or Cursor?
