Module 1

Installation & Setup

Download, install, and set up Google Antigravity on your Windows computer.

⏱️ Estimated time: 20 minutes

In this module, you will download Google Antigravity, install it on your Windows computer, and take a tour of its main features. By the end, you will be ready to start building your first app.

Step 1: Get a Google Account

Antigravity requires a personal Google (Gmail) account to sign in. If you already have one, you can skip to Step 2.

  1. 1Open your browser and go to accounts.google.com/signup
  2. 2Fill in your name, choose a username (this will be your email address), and create a password.
  3. 3Follow the on-screen instructions to complete the setup.
  4. 4Make a note of your email and password — you will need them in the next step.

Step 2: Download and Install Antigravity

  1. 1Open your browser and go to antigravity.google/download
  2. 2The website will detect your operating system. Click the "Download for Windows" button.
  3. 3Once the download is complete, find the file in your Downloads folder (it will be called something like AntigravitySetup.exe).
  4. 4Double-click the file to start the installer.
  5. 5If Windows asks "Do you want to allow this app to make changes?", click "Yes".
  6. 6Follow the installer steps — the default options are fine for most people.
  7. 7When the installation is finished, Antigravity will open automatically.
Go to Official Download Page

Important ⚠️

Only download Antigravity from the official website (antigravity.google/download). Do not download it from other websites — they may not have the latest version or could contain harmful software.

Step 3: First Launch Walkthrough

When Antigravity opens for the first time, it will guide you through a few setup steps:

  1. 1Sign in with your Google Account. A browser window will open for you to log in, then you return to Antigravity automatically.
  2. 2If Windows shows a blue "Windows protected your PC" warning (because the app is new), click "More info" and then "Run anyway". This is safe when you downloaded from the official website.
  3. 3Choose a theme (light or dark) — you can change this later in Settings.
  4. 4That is it! Antigravity opens and you are ready to create your first project.

How the AI agent works 💡

In Antigravity, the AI works as an agent. You describe what you want, and the agent plans the work, writes the code, runs it, and can even test it in the browser for you. You mostly watch and give feedback — no coding needed.

You stay in control. You can approve steps as they happen, and later, in Settings, you can change how much freedom the agent has — from asking you before every action to a faster, more hands-off mode once you feel confident.

Step 4: Understanding the Interface

The Antigravity interface has four main areas. Here is what each one does:

Google Antigravity
Explorer
Search
Settings
Main Editor Area
This is where Antigravity shows the files
and code it creates for your app.
You do not need to edit code here —
the AI does that for you.
Agent Manager
You type here
Tell the AI what to build
Artifacts
Plans, task lists, code
Terminal — Shows logs and command output
Sidebar (left) — Shows your project files and folders. Like a file manager for your app.
Main Editor (center) — Displays the code and files the AI creates. You usually do not need to touch this area.
Agent Manager (right) — This is where you talk to the AI. Type your instructions here and see the AI's plans and progress.
Terminal (bottom) — Shows technical output and logs. Useful for checking if things are running correctly.

Where to Find Settings

Finding Settings 💡

Click the gear icon in the bottom-left corner of the sidebar, or press Ctrl + , (comma) to open Settings.

From here, you can change the theme, switch AI models, manage projects, and configure security settings.

Choosing an AI model 💡

Antigravity can use different AI “brains” (called models). By default it uses a fast Google Gemini model (currently Gemini 3.5 Flash), which is great for everyday building. For harder tasks, you can switch to a more powerful model such as Gemini Pro or Claude using the model dropdown near the chat box.

For this course, the default model works perfectly — there is no need to change it.

Connecting Tools and Extensions (MCP Servers)

Antigravity can connect to external tools and services using something called MCP (Model Context Protocol) servers. Think of these as plug-ins that give the AI extra abilities.

For example, MCP servers can connect Antigravity to:

  • Google Cloud services (BigQuery, Cloud SQL)
  • Databases (like Supabase or Firebase)
  • Code hosting (GitHub)
  • Deployment tools (Netlify, Vercel)
  1. 1Open Settings (the gear icon), then find the "MCP" section under Customizations.
  2. 2Browse the available MCP servers and add the one you need.
  3. 3Some servers ask for a login or a key — just follow the on-screen steps to connect.
  4. 4Once added, the AI can use that tool automatically when you ask it to.

You do not need MCP right away 💡

For this course, you do not need to set up any MCP servers. We will mention them in Module 3 and 4 when we connect to external services. For now, just know they exist.

Language Support

Can you use Antigravity in your own language? 💡

Interface language: Yes! Because Antigravity is built on VS Code technology, you can install language packs to change the menus and buttons to your language. Go to Extensions (Ctrl+Shift+X), search for your language pack (e.g., “Japanese Language Pack”), and install it.

Prompting in your language: Yes, you can type your prompts in many languages and Antigravity will understand them. However, it works best with English. If you want the AI to always reply in your language, add a rule like “Always reply in Spanish” in your project rules file.
