# Antigravity: Google's NEW Agentic Editor in 7 Minutes Source: https://www.youtube.com/watch?v=wbPpvjcAHew Recap page: https://rapidrecap.app/video/wbPpvjcAHew Generated: 2025-11-23T04:02:51.775+00:00 --- ## Quick Overview The video showcases Google Antigravity, a new agentic editor environment where the AI agent can perform complex, multi-step development tasks, such as building a Next.js application from scratch, interacting with the terminal, editing code, and testing the resulting application live in a browser, all managed through a centralized Agent Manager interface. **Key Points:** - Google Antigravity is an agentic editor that manages complex development tasks, demonstrated by building a 'Developers Digest' Next.js application. - The workflow involves giving the agent a high-level prompt (e.g., 'I want to create a new Next.js application that reads Developers Digest'), which it breaks down into a plan and executes sequentially. - The agent interacts with a simulated terminal environment to run commands like 'npx create-next-app' and package installations, showing output and checking command status. - The environment features an Agent Manager UI allowing users to switch between Workspaces (like 'antigravity' and 'example-space-2'), select different LLM models (like Gemini 3 Pro and Claude Sonnet 4.5), and choose between 'Planning' and 'Fast' modes. - During development, the agent created HTML, CSS, and JavaScript files, and demonstrated browser interaction, including navigating URLs and clicking elements to verify functionality. - The final result was a fully built 'Developers Digest' landing page with modern design elements, which the agent tested by scrolling, hovering, and interacting with forms. - The developer notes that while some models like GPT-4 128k are powerful, they may be rate-limited, suggesting using models like Gemini 3 Pro for high-volume development tasks. ![Screenshot at 0:01: The initial screen showing the 'Google Antigravity' logo and branding, setting the stage for the demonstration of the agentic editor environment.](https://ss.rapidrecap.app/screens/wbPpvjcAHew/00-00-01.png) **Context:** This video provides a demonstration and overview of Google Antigravity, an experimental agentic development environment that allows AI agents to handle entire software development workflows within a unified interface. The demonstration focuses on using the Agent Manager to initiate a project, select execution modes (Planning vs. Fast), and manage multi-step tasks like setting up a Next.js project, writing code, running terminal commands, and verifying the output in a controlled browser environment. ## Detailed Analysis The video introduces Google Antigravity, an agentic editor designed to manage complex software development tasks autonomously. The demonstration begins with the agent being prompted to create a Next.js application called 'Developers Digest' with specific aesthetic requirements (modern, black/white/purple/blue theme). The agent first enters 'Planning' mode (0:57) within the 'antigravity' workspace, develops a comprehensive task list, and then transitions to execution. The agent operates by running terminal commands (3:55), installing dependencies like Tailwind CSS, and managing the Next.js setup process, showing real-time terminal output and status checks (4:07). The agent also interacts with a live browser window to test the generated application, navigating to URLs, hovering over elements, and verifying interactions like button clicks and form submissions (4:35-5:18). Key features highlighted include the ability to switch between different LLM models (Gemini 3 Pro, Claude Sonnet 4.5, GPT-4 128k) and conversation modes (Planning for complex tasks, Fast for simple ones). The workflow is highly transparent, showing the agent's thoughts, actions, and file modifications in real-time within the Agent Manager interface. The final deployed application, a 'Developers Digest' landing page, is shown to be fully functional, demonstrating the agent's capability to execute an entire development cycle from concept to verification. ### Antigravity Overview - Agentic editor for complex development - Agent Manager UI for task/workspace control - Supports multiple LLMs (Gemini, Claude, GPT) ### Project Initialization - Agent tasked with creating a 'Developers Digest' Next.js app - Uses 'Planning' mode to create a detailed task list - Executes terminal commands for project setup and dependency installation ### Agent Interaction & Execution - Agent manages file creation (index.html, styles.css, script.js) - Agent interacts with a live browser to test functionality - Agent executes steps like scrolling, hovering, and form submission verification ### Model and Mode Selection - User can select models like Gemini 3 Pro (High) or Claude Sonnet 4.5 - Modes include 'Planning' (for complex tasks) and 'Fast' (for simple tasks) ### Result Verification - Agent completes the build and provides verification steps, including screenshots, showing the final functional landing page with modern design elements ![Screenshot at 0:02: The agent environment showing the initial file structure setup for the flight tracker project in the IDE.](https://ss.rapidrecap.app/screens/wbPpvjcAHew/00-00-02.png) ![Screenshot at 0:10: The agent demonstrating the 'Flight Tracker' application running in the controlled browser window after initial setup.](https://ss.rapidrecap.app/screens/wbPpvjcAHew/00-00-10.png) ![Screenshot at 0:38: A complex task list view within the Agent Manager, detailing the steps for creating the 'Developers Digest' landing page.](https://ss.rapidrecap.app/screens/wbPpvjcAHew/00-00-38.png) ![Screenshot at 2:24: The agent actively generating and editing multiple source files \(index.html, styles.css, script.js\) for the new application.](https://ss.rapidrecap.app/screens/wbPpvjcAHew/00-02-24.png) ![Screenshot at 4:17: The agent running the development server, indicated by the local address displayed in the browser preview, ready for functional testing.](https://ss.rapidrecap.app/screens/wbPpvjcAHew/00-04-17.png)
