This tutorial will show you the steps to switch between themes in ChatGPT, including:

Follow these instructions to modify the theme settings in ChatGPT.
Enabling Dark Mode On Desktop

At a glance: Select your name at the bottom-left corner, clicking on “Settings & Beta” (for free users) or “Settings” for Plus, and choosing “Dark” under the “Theme” menu.
Detailed steps are as follows:
Access Settings:
- Open ChatGPT and click on your profile icon at the bottom-left.
- Choose “Settings & Beta” or “Settings”
- A settings menu will appear.
Changing Theme:
- Find the “Theme” option and click it.
- It might display “System” by default, or “Light” if that’s your current setting.
- Select “Dark” to switch modes.
- ChatGPT will then switch to dark mode.
For syncing with your device’s settings, pick “System,” which will automatically adjust ChatGPT’s theme based on your device’s current theme.
By default, most browser operate in light mode, so Light Mode and System won’t display any changes.
Enabling Dark Mode On Mobile

At a glance: To adjust the theme in ChatGPT on your mobile device, tap the three dots icon at the top left corner, go to “Settings,” then “Color Scheme”, and select one of three available options.
Here’s an extended tutorial on how you can switch to dark mode on mobile:
Settings:
- Open the ChatGPT app.
- Tap the menu icon on the top-left.
- Click on your name in the bottom-left corner.
- You’ll see the settings menu.
Adjusting Color Scheme:
- Tap on “Color Scheme”.
- Choose between System, Dark, or Light.
- For this guide, we switched from “System” to “Dark.”
You can switch back to light mode simply by clicking on light.
Again, System will adapt the color scheme that your mobile phone uses.
For iPhone users, go to “Settings”, then tap “Display & Brightness”. Select “Dark” to turn on the dark mode.
For Android users, it’s similar, i.e., open the “Settings” app, then select “Display”, and lastly turn “Dark theme” on or off.
