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.
