Anti-gravity: A New AI-Powered Code Editor

This video introduces and reviews "Anti-gravity," a new AI-powered code editor positioned as a strong alternative to Cursor. The presenter aims to test its capabilities and compare it against Cursor.

Installation and Initial Setup

The process begins with downloading Anti-gravity from anti-gravity.google. The installation involves importing settings from Cursor, choosing a dark mode, and configuring agent-assisted development. The presenter opts for an "agent assisted auto execution policy" with an "always proceed" review policy, which customizes the configuration. After logging into Google, the user agrees to data collection for interactions. The interface is noted to be similar to Cursor.

Core Features and Modes

Anti-gravity offers two primary modes:

• Planning Mode: (Not extensively detailed in the demo)
• Fast Mode: Used for quicker operations.

The editor supports various AI models, with Gemini 3 Pro being highlighted as the most advanced available. Users can switch between the default editor view and the "Agent Manager" mode.

Agent Manager and Project Development

The Agent Manager provides a consolidated view of projects and AI interactions. The presenter demonstrates its use by initiating two simultaneous development tasks:

1. Twitter-like Application: The AI is tasked with developing a Twitter-like application with a database and a similar UI. The AI automatically writes code, and the process is auto-approved.
2. Finance Tracking App: A second conversation is started to create a finance tracking app.

Both applications are developed concurrently. The "Inboxes" feature alerts the user for any necessary approvals. The Agent Manager allows for multiple workspaces to be opened simultaneously. The presenter asks the AI to identify an application and explain how to get started, which it successfully does.

Editor Interface and Functionality

The default editor mode displays the development steps on the right-hand side, mirroring Cursor's functionality. Below the chat interface, users can find sections for "Changes Overview," "Terminal," "Background Process," and "Artifacts." The presenter likens Anti-gravity to a combination of "wind surf and cursor."

Finance Tracking App Demonstration

The finance tracking app is completed, and its URL is provided. The application features a clean interface for tracking income and expenses. The presenter successfully adds a transaction ("buy a computer for 10,000") and observes it reflected in the app. The AI is then asked to modify the application further by using terminal commands to publish it to GitHub using gh.

GitHub Integration and Model Switching

Initially, the model (likely Gemini 3 Pro) encounters a quota limit. The presenter switches to Claude 4.5, which successfully initiates the git init process and pushes the application to GitHub, ensuring no secrets are stored. The presenter expresses appreciation for the free access to these models and the seamless GitHub integration.

Twitter App Demonstration and Automated Testing

The Twitter app development is shown to be awaiting approval. The AI prompts for a preview in the browser. Anti-gravity includes a built-in browser that can be extended with Chrome extensions. The AI automatically tests the application by visiting it, capturing screenshots, and identifying errors. This automated testing includes a video recording of the process.

Browser Control and UI Fixes

The AI's control over the browser is indicated by a glow. The application is a close replica of Twitter, with a minor UI issue where a header is positioned incorrectly. The AI is shown processing further to fix this.

Additional Features

• New Tab: Opens a new tab within the integrated browser.
• Move Work into Folder: Allows users to organize code from the playground into specific folders.
• Open Browser Preview: Shows a preview of the application in the integrated browser.
• Toggle Terminal: Opens and closes the terminal.
• Open Editor: Switches to the main editor view.
• Follow Along with the Agent: Tracks the AI's actions.

Playground Functionality

The "Playground" is highlighted as a valuable feature for rapid prototyping. It allows developers to quickly build applications without immediate concern for file organization, focusing solely on development. Once satisfied, the code can be moved to a chosen folder.

Twitter App Completion and Review

The Twitter app is successfully completed with the correct layout. The AI demonstrates posting a test comment and controlling the page. The presenter is impressed with the smoother integration and the unique automated review of the page, including browser interaction, screenshots, and error identification. The approval process is similar to Cursor.

Conclusion and Recommendation

The presenter is "super impressed" with Anti-gravity and intends to use it regularly to enhance workflow speed. They encourage viewers to try it and share their feedback. A comparison video with Cursor 2.0 is mentioned, with a link provided for viewers to compare the two tools. The presenter highly recommends watching the Cursor 2.0 video.
