Features

Dark mode

You can toggle dark mode in the View menu or with Command d / Control d.

You can prevent others from looking at who you're chatting with by enabling the “Hide Names and Avatars” feature in the “View” menu or with Command/Control Shift n.

Vibrancy

On macOS, you can toggle the window vibrancy effect in the View menu.

Privacy

You can choose to prevent people from knowing when you have seen a message and when you are currently typing. These settings are available under the Caprine/File menu.

Mute desktop notifications

You can quickly disable receiving notifications from the Caprine/File menu or the Dock on macOS.

Hide notification message preview

You can toggle the Show Message Preview in Notification setting in the Caprine/File menu.

Prevents link tracking

Links that you click on will not be tracked by Facebook.

Jump to conversation hotkey

You can switch conversations similar to how you switch browser tabs: Command/Control n (where n is 1 through 9).

The interface adapts when resized to a small size.

Desktop notifications

Desktop notifications can be turned on in Preferences.

You can toggle whether Caprine stays on top of other windows in the Window/View menu or with Command/Control Shift t.

Work Chat support

Support for Work Chat: Messenger for Workplace. You can switch to it in the Caprine/File menu.

Code blocks

You can send code blocks by using Markdown syntax.

Background behavior

When closing the window, the app will by default continue running in the background, in the dock on macOS and the tray on Linux/Windows. Right-click the dock/tray icon and choose Quit to completely quit the app. On macOS, click the dock icon to show the window. On Linux, right-click the tray icon and choose Toggle to toggle the window. On Windows, click the tray icon to toggle the window.

Note that you can change the behavior of Caprine so that the app closes when the window is closed. For this, you'll need to go to the settings and click on Quit on Window Close.

Quick access to conversations from the Dock menu (macOS only)

Touch Bar support (macOS only)

Custom languages for spell-check (Not for macOS)

Users can select supported languages from Conversation → Spell Checker Language.

macOS detects the language automatically.

Custom styles

Advanced users can modify the colors/styles of Caprine. Click the menu item Caprine/File → Caprine Settings → Advanced → Custom Styles and a CSS file will open up in your default editor.

Menu Bar Mode (macOS only)

You can enable Show Menu Bar Icon in the Caprine Preferences menu to have a Caprine icon in the menu bar. The icon will indicate when you have unread notifications and you can click it to toggle the Caprine window. You can also toggle the Caprine window with the global shortcut Command Shift y.

You can also remove Caprine from the Dock and task switcher by clicking Hide Dock Icon menu item from the menu bar icon. There will then no longer be any menus for the window, but you can access those from the Menu item in the menu bar icon menu.
