  description

  ChatGPT Material Dark transforms ChatGPT into a polished dark workspace with live theme controls, cleaner contrast, and less visual clutter.
  
    Built for people who spend real time in ChatGPT, this extension gives you a better-looking interface without needing to edit CSS or install a separate userstyle manager. Open the popup, pick your colors, save a preset, and
    the theme updates live in your ChatGPT tabs.
  
    Features:
  
    • Custom Material Dark theme for ChatGPT
    • Live color controls for user messages, assistant output, links, headings, borders, and chat background
    • Gradient background support with adjustable colors and angle
    • Built-in theme presets including Material Dark, OLED Black, Deep Ocean, and Deep Forest
    • Custom named presets so you can save your own themes
    • Wide Mode for a roomier chat layout
    • Hide side clutter option for a cleaner workspace
    • No text wrap option for fuller sidebar titles
    • Settings sync across Chrome profiles
    • Works on chatgpt.com and supported ChatGPT login pages
  
    Why install it?
  
    ChatGPT’s default interface is functional, but it is not very personal. ChatGPT Material Dark gives you control over the parts of the UI you look at all day: the chat background, message bubbles, assistant output, borders,
    links, and accent colors.
  
    Use OLED Black for a minimal low-glare setup, Deep Ocean or Deep Forest for a softer themed workspace, or build your own look from scratch with custom presets.
  
    Privacy-first by design:
  
    • No analytics
    • No tracking
    • No ads
    • No data selling
    • No collection of your chats or personal content
  
    Your preferences are stored using Chrome storage so your theme can sync across your signed-in Chrome browsers. The extension only changes the appearance of supported ChatGPT pages.
