Like all other popular websites, ChatGPT provides a dark mode option for its users. Dark mode, which displays light text on a dark background, has several benefits, including reducing eye strain and fatigue, improving readability, and providing a more ambient tone. This wikiHow guide will teach you how to enable dark mode on ChatGPT, whether you're using the app on your Android, iPhone, or iPad, or the website on your computer.

Enabling Chat GPT Dark Mode: Quick Steps

To switch to dark mode in the mobile app, tap your profile icon, go to Personalization, and select Dark under “Color scheme.” If you don't see these options, tap Appearance on the settings menu instead, then select Dark. In a web browser, click your username, select Settings, and choose Dark under “Appearance.”

Tips

Theme settings only apply to the device and platform where you set them. For example, changing the theme on the web won’t affect the mobile app, and changes on Android won’t apply to iOS. You need to adjust the theme separately on each device or platform.^{[2]
