The landscape of software development has shifted dramatically. We’ve moved from manual coding to AI-assisted coding, and now, we’ve entered the era of "Vibe Coding" with Google Antigravity. This revolutionary tool allows anyone to build complex, functional applications using nothing but natural language prompts.

In this guide, we’ll explore how to master Antigravity, look at real-world success stories like MoneySense AI and MenuGo, and provide you with the tips and tricks needed to separate yourself from the beginners.

What is Google Antigravity?

Google Antigravity is an agent-first development platform that acts as your personal software engineering team. It doesn’t just suggest code; it plans, writes, executes, and tests applications autonomously.

The Core Architecture

To truly master Antigravity, you must understand its "Mission Control" setup:

Component	Function
Agent Manager	Your communication hub where you describe tasks and monitor the agent’s progress.
Editor	A VS Code-like interface where you can see the project files and terminal commands in real-time.
AI Agent	The "worker" that uses models like Gemini 3 Pro, Claude, or GPT to build your app.
Browser Agent	A built-in Chrome instance that the agent uses to test your app just like a human would.

Real-World Success Stories

Antigravity isn’t just for toy projects. It’s being used to refine and build professional-grade applications.

1. MoneySense AI (Refined with Antigravity)

MoneySense AI is a sophisticated financial management tool. While the core logic was established, the developers used Antigravity to refine the user experience and visual interface. By feeding the agent existing code and brand guidelines, they were able to:

• Implement complex data visualizations for spending trends.
• Refine the responsive layout for mobile users.
• Debug edge cases in the transaction categorization engine.

2. MenuGo

MenuGo is a brilliant example of a "Vibe Coded" success. It’s a digital QR code menu generator for restaurants. Built with the speed and efficiency of Antigravity, MenuGo features:

• AI Menu Extraction: Upload a PDF, and the AI extracts items, prices, and descriptions.
• Dynamic Pricing: A feature that allows restaurants to adjust prices based on demand.
• Multilingual Support: Instant translation for international guests.

MenuGo demonstrates how Antigravity can handle not just the frontend, but also complex backend integrations and AI-driven features.

Pro Tips & Tricks for Antigravity

To get the most out of this tool, you need to go beyond simple prompts. Here are the "Hidden Features" used by pros:

1. The Power of .md Context Files

Don’t just type a long prompt into the chat. Create dedicated Markdown files in your workspace:

• gemini.md: Detailed technical requirements and feature lists.
• brand_guidelines.md: Define your colors, typography, and UI "vibe."

# System Instructions: Personal Finance Dashboard

## Goal
Build a modern, responsive **Personal Finance Dashboard** application for tracking income, expenses, savings, and budget. The application must be visually appealing and adhere strictly to the provided `brand_guidelines.md`.

## Core Features

### 1. Dashboard Page
- **Header:** Display "Welcome Back, [User Name]" and a quick summary of **Total Balance**.
- **Key Metrics Cards (4 Cards):**
- Card 1: **Total Balance** (Current available funds)
- Card 2: **Total Income** (Last 30 days)
- Card 3: **Total Expenses** (Last 30 days)
- Card 4: **Total Savings** (Year-to-date)
- **Budget Tracker:** A visual component (e.g., a progress bar or donut chart) showing monthly spending against a set limit.
- **Recent Transactions:** A table listing the 5 most recent transactions (Date, Description, Category, Amount).

### 2. Transactions Page
- **Transaction History:** A filterable and searchable table of all transactions.
- **Add Transaction Form:** A modal or form to input new transactions, including:
- Type (Income/Expense)
- Amount
- Description
- Category (e.g., Food, Bills, Salary, Investment)
- Date

### 3. Wallet Page
- **My Cards Section:** Display simulated card details (Card Name, Last 4 digits, Expiry).
- **Card Management:** Functionality to "Add New Card" (simulated input).

### 4. Goals Page
- **Savings Goals:** Display a list of active savings goals (e.g., "Vacation Fund").
- **Goal Progress:** A visual indicator (e.g., progress bar) showing how close the user is to reaching the goal.
- **Add Goal Form:** Form to set a new savings goal (Goal Name, Target Amount, Current Saved).

## Technical Requirements

- **Framework:** Use a modern, component-based framework (e.g., React/Next.js) for the frontend.
- **Data Storage:** Use local storage or a simple JSON file structure for data persistence (no complex database required for this MVP).
- **Responsiveness:** The application must be fully responsive and look excellent on both desktop and mobile devices.
- **Testing:** The agent must run a full browser test suite to verify all navigation links and the "Add Transaction" functionality work correctly.
- **Code Quality:** Ensure the code is clean, well-commented, and follows modern best practices.

# Brand Guidelines: JM Solutions Finance Dashboard

## Brand Identity

- **Brand Name:** JM Solutions
- **Logo Usage:** A clean, minimal icon representing growth (e.g., an upward-trending arrow or a simple leaf/chart icon). The logo should be placed in the top-left corner of the navigation bar.
- **Logo Don'ts:** Avoid overly complex or cartoonish logos. Do not use the logo on the main dashboard area.

## Color Palette

| Name | Hex Code | Usage |
| :--- | :--- | :--- |
| **Primary Color** | `#007BFF` (Dark Blue) | Main call-to-action buttons, navigation bar background, key metrics highlights. |
| **Secondary Color** | `#28A745` (Success Green) | Income and positive growth indicators. |
| **Tertiary Color** | `#DC3545` (Danger Red) | Expense and negative trend indicators. |
| **Neutral Color** | `#F8F9FA` (Light Gray) | Backgrounds, card borders, and subtle separators. |
| **Text Color** | `#343A40` (Dark Gray) | Primary text for readability. |

## Typography

- **Primary Font:** Sans-serif (e.g., Inter, Roboto, or system default).
- **Headings (H1, H2):** Bold, Primary Color.
- **Body Text:** Regular weight, Text Color.
- **Data/Metrics:** Monospace or a slightly heavier weight for numerical data.

## UI Elements and Vibe

- **Vibe:** Clean, professional, minimal, and data-focused.
- **Cards:** Use a light gray background (`#F8F9FA`) with a subtle shadow. All corners should be slightly rounded (e.g., 8px border-radius).
- **Buttons:** Primary buttons should use the **Primary Color** (`#007BFF`) with white text. Secondary buttons should be outlined.
- **Data Visualization:** Charts and graphs should use the Primary, Secondary, and Tertiary colors to represent balance, income, and expenses, respectively.
- **Spacing:** Maintain generous white space to ensure a clean, uncluttered look. Use a consistent 8-point grid system for all spacing.
- **Icons:** Use a modern, line-based icon set (e.g., Feather or Heroicons) for navigation and feature indicators.

The agent will reference these files constantly, leading to much higher quality outputs.

2. Master the "Planning Mode"

For complex apps, always use Planning Mode. This forces the agent to write out its steps before execution. If the plan looks wrong, you can correct it before a single line of code is written, saving you time and rate limits.

3. Leverage MCP Servers

The Model Context Protocol (MCP) is Antigravity’s superpower. You can connect your app to:

• n8n: For complex backend automations.
• Slack/Google Sheets: To pull or push data externally.
• Custom APIs: To give your agent access to any service you need.

4. Configure "Always Proceed" for Speed

If you’re confident in your instructions, go to User Settings > Agent and set the review policy to "Always Proceed." This allows the agent to work autonomously while you grab a coffee, coming back to a finished (or nearly finished) product.
