Key Points

• Download Availability
  Anti-Gravity is completely free and available from Google at antigravity.google/download. It runs on macOS (both Apple Silicon and older Intel processors), Windows (64-bit), and Linux—covering a wide range of systems including computers as old as 10 years.
• Installation Process
  Follow the prompts and accept the defaults during installation. Kimberly recommends installing on a drive separate from your main operating system for organization, but you can place it wherever you're comfortable.
• Initial Setup Mode
  When first launched, Anti-Gravity asks how you want to use the agent. This simply determines your initial settings and can be changed later. Kimberly recommends "agent assisted development" and starting with higher security settings until you're comfortable with the program's power.
• Opening a Workspace Folder
  After installation, open any work folder on your computer—it can be entirely new or existing. This becomes your workspace where Anti-Gravity will read and write files.
• Two Main Windows
  Anti-Gravity has two primary views: the Editor (bottom window) with a file explorer, preview pane, and chat window, and the Agent Manager (explored later). The file explorer syncs with your Windows/Mac folder—anything dropped in appears in both places.
• Available AI Models
  The application offers multiple AI models including Gemini 3 Pro High (fast thinking), Gemini 3 Pro Low, Gemini 3 Flash (almost as good as Pro but faster and cheaper), Claude 4.5 Sonnet (thinking and non-thinking modes), and Opus. There's also GPT-OSS (open source, limited usage).
• Free Usage and Limits
  You can use Anti-Gravity completely free by logging in with your Google account. Free users have weekly limits, but usage resets every five hours. On the Pro subscription ($20/month), you rarely run out, and if one model's quota is exhausted, you can switch to another.
• Claude Access Advantage
  Anti-Gravity offers more free Opus 4.5 usage than even the paid Claude subscription provides—making it an exceptional value for accessing Claude's capabilities.

Summary

In this session, Kimberly walks students through downloading and installing Anti-Gravity, explaining its availability across Mac, Windows, and Linux platforms—even on older machines. She guides viewers through the installation prompts, initial security settings, and opening their first workspace folder. Kimberly then introduces the main interface, highlighting the file explorer, preview pane, and chat window where you interact with the AI. She covers the impressive array of available AI models including Gemini and Claude variants, explaining the free usage model with weekly limits that reset regularly. The key takeaway is that Anti-Gravity is completely free to try, offers more Claude access than paid subscriptions, and allows users to switch between models when one runs out—making it an accessible and powerful tool for writers at any budget.
