On Android mobile app you definitely can switch the OS to the night mode and Intercom mobile app will switch to it as well. And for the web app you can use plugins like "dark mode" or any other one https://chrome.google.com/webstore/detail/dark-mode/dmghijelimhndkbmpgbldicpogfkceaj/p>

There is no specific setting inside the platform to switch to the dark mode

Hey @User1055  Shauna here from Support! 

Wanted to update this here - To switch to between dark and light theme, go to a conversation in the Inbox and click the lightning bolt in the composer to open the menu (or use the keyboard shortcut ⌘K for Mac or Ctrl+K for Windows) and type in "dark" or "light", and select "switch to dark\light theme":

You can also switch between dark and light while in the Inbox here:

Note: Dark mode is only available in the Inbox and not in other parts of Intercom.

@Shauna Is it planned to make the other parts of Intercom  available in dark mode? Its kind of confusing to switch between dark/light all the time

Hi @Christian Leo 

This is a feature that a lot of our customers have asked for.

I’ll add your request there, whenever we do release new features, we'll announce it on the Product Changes page, so I'd recommend keeping an eye here!
