Getting Started with Atlas

Your Complete Setup and User Guide

Before You Begin

ChatGPT Atlas is currently available exclusively for macOS. Before installation, ensure your system meets the requirements and that you have a ChatGPT account (free or paid) to access the browser's AI features.

Prerequisites

  • Mac running macOS 12 (Monterey) or later
  • At least 8GB of RAM (16GB recommended)
  • 500MB of available storage space
  • Active internet connection
  • ChatGPT account (create one at chat.openai.com if needed)

Installation Process

Installing Atlas is straightforward and follows standard macOS application installation procedures.

Step-by-Step Installation

  1. Visit the Official Download Page

    Navigate to OpenAI's official website and locate the Atlas download page. Always download from official sources to ensure security.

  2. Download the Installer

    Click the download button to get the ChatGPT-Atlas.dmg file. The download is approximately 200-300MB depending on the version.

  3. Open the DMG File

    Once downloaded, double-click the DMG file to mount it. A window will appear showing the Atlas application icon.

  4. Drag to Applications

    Drag the ChatGPT Atlas icon to your Applications folder. This copies the app to your system.

  5. Launch Atlas

    Open your Applications folder and double-click ChatGPT Atlas to launch it for the first time.

  6. Grant Permissions

    macOS may show a security prompt. Click "Open" to confirm you want to run the application.

Security Note

If macOS prevents Atlas from opening because it's from an "unidentified developer," you may need to right-click the app, select "Open," and then click "Open" in the dialog. This is a one-time step.
