What you'll learn

  • Master the Google Antigravity IDE: Transition from a manual "Coder" to a "Software Architect" by learning the interface, shortcuts, and "Agent-First" workflow.
  • Build a Complete AI SaaS ("QuizGenius"): Create a fully functional Flashcard App with React, Vite, and TailwindCSS without writing the boilerplate yourself.
  • Orchestrate Multi-Agent "Swarms": Learn how to run parallel agents (Backend, Frontend, Logic) simultaneously to build complex features in record time.
  • Implement Fullstack Logic: Connect your app to a Supabase Database for persistence and integrate the Google Gemini API to generate dynamic content.
  • Master Context Engineering: Learn how to use @Mentions (@Codebase, @Docs, @Files) to guide the AI with surgical precision and prevent hallucinations.
  • Automate DevOps & Git: Let the Agent handle version control, write semantic commit messages, and manage your GitHub repository.
  • Deploy to Production: Take your project from "localhost" to a live URL by deploying to Vercel with a production-ready build configuration.

Course content

3 sections • 13 lectures • 1h 38m total length

  • Installation & Onboarding: Getting into the Cockpit3:25

    Install anti-gravity on your operating system, onboarding with a hands-off approach as you manage a team of agents to build backend and frontend for saas apps.

  • Project Scaffolding: Setting Up the Environment9:38
  • The Command Center: Interface & Customization10:06

    Explore customizing the anti-gravity agent by setting privacy rules with a gravity ignore, selecting models and quotas, and building reusable workflows and rules for workspace-specific tasks.

  • Mastering Context: How to Use @Mentions Correctly10:50

    Enhance ai agent prompts by embedding context using mentions, code files, directories, and terminals, enabling precise references to functions, errors, and workspace problems.

  • Warm-up Project: Building a Web App Calculator9:14

    Create a web app calculator with the anti-gravity agent, using the agent manager to track tasks, test in-browser, and review changes and walkthroughs.

Requirements

  • A Google Account: Required to access the Antigravity IDE and Gemini API keys.
  • Free Developer Accounts: We will use GitHub, Supabase, and Vercel. All of these offer free tiers, and we will set them up together in the course.
  • No AI Experience Needed: You do not need prior experience with LLMs or Prompt Engineering. We start from the very basics.

Description

Are you still writing code line-by-line, or are you ready to start orchestrating? Welcome to the era of "Agentic Coding".

Software development has changed forever. With the release of the Google Antigravity IDE and Gemini, your role is shifting from a "Code Writer" to a Software Architect. In this course, you won't just memorize syntax—you will learn how to command an army of AI Agents to build complex, production-ready applications in record time.

In this hands-on masterclass, we will build "QuizGenius" together—a fully functional Fullstack SaaS application.

We start from zero and go all the way to a live deployment. The twist? You will write almost no code manually. Instead, you will master the revolutionary "Swarm Workflow", where we run Backend, Frontend, and Logic Agents simultaneously to build features in parallel.

Here is exactly what you will master:

  • Google Antigravity Mastery: Navigate the new IDE, understand the "Agent-First" interface, and learn how it outperforms traditional editors like VS Code.

  • Context Engineering: Learn the art of using @Mentions (@Codebase, @Docs, @Files) to give the AI surgical context and eliminate hallucinations.

  • The "Swarm" Workflow: Orchestrate multiple agents at once. Watch a Database Agent write SQL while a Frontend Agent designs the UI—all under your command.

  • Pain-Free Fullstack Development:

    • Frontend: React, Vite & TailwindCSS (generated and styled by AI).

    • Backend: Supabase Database setup & Row Level Security policies.

    • AI Integration: Connecting the Google Gemini API to generate dynamic content.

  • Agentic DevOps: Let the Agent manage your Git repository, write semantic commit messages, fix build errors, and deploy your app to Vercel.

Why this course?

Most AI coding courses only show you how to generate small snippets. This course teaches you how to manage entire projects. You will learn the strategies to go from a raw idea to a deployed product by leading the AI as your "Junior Developer team".

This course is perfect for you if:

  • You are a Developer looking to 10x your productivity and automate the boring parts of coding.

  • You are an Entrepreneur or Indie Hacker who wants to build MVPs fast without getting stuck in technical weeds.

  • You want to future-proof your career and stay ahead of the curve in the Agentic AI revolution.

Stop typing. Start building. Join the course and become an AI Architect today!

Who this course is for:

  • Developers & Engineers who want to stop typing boilerplate code and start architecting complex solutions 10x faster.
  • Entrepreneurs & Indie Hackers who need to build and deploy MVPs (Minimum Viable Products) in hours instead of weeks.
  • Beginners & Students who find syntax frustrating and want to focus on building real, working applications immediately.
  • Early Adopters who want to stay ahead of the curve by mastering the "Agentic Workflow" before it becomes the industry standard.
