Antigravity Browser 🛡️✨

The Local-First AI Browser.

Antigravity is a concept browser that runs advanced AI models entirely on your device. No cloud, no subscriptions, no data leaks. Just you, the web, and a powerful neural engine running in your browser tab.

Features

• Local Intelligence: Powered by WebLLM and WebGPU, running models like Llama 3 and Gemma 2 locally.
• Privacy First: Your chats and browsing data never leave your machine.
• Premium UI: A sleek, dark-mode interface designed for focus and flow.
• Instant Answers: Ask questions about the web, summarize content, and generate ideas without latency.

Getting Started

Prerequisites

• A modern browser with WebGPU support (Chrome 113+, Edge, or others).
• A GPU with at least 4GB of VRAM (recommended for decent performance).

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/antigravity-browser.git
   cd antigravity-browser

2. Install dependencies:

   npm install

3. Run the development server:

   npm run dev

4. Open http://localhost:5173 and start browsing!

How it Works

Antigravity uses WebLLM to download and execute Large Language Models (LLMs) directly in the browser's runtime using WebGPU. This means the "backend" is actually running inside your frontend application.

Roadmap

• Context Awareness: Allow the AI to read the current tab's content (DOM).
• History & Memory: persistent local vector database for long-term memory.
• Extensions: Support for standard web extensions.
• Multi-Model Support: Switch between Llama, Gemma, Phi, and more.
