Getting Started with CoScreen

Step 1: Install CoScreen

Download CoScreen for free (macOS and Windows).

Step 2: Setup CoScreen

Launch the CoScreen desktop app, sign up and follow the onboarding steps.

Step 3: Connect to your first CoScreen

Almost there - you can connect with your collaborators using a variety of ways:

  • Click on a CoScreen link if you were already invited or create a new one.
Creating a new CoScreen or join by ID
Add a collaborator so you can call each other directly

Step 4: Chat via audio & video

Once you and your collaborators (up to 10) in a CoScreen, simply unmute your self to talk to each other and activate your webcam to see each other.

Click on the '☰' icon on the top right of the CoScreen menu to change the video layout.

Turn on your camera if you want to video chat or simply unmute yourself for simple audio chat

Step 5: Share windows

Move your mouse pointer over any of your open windows and click 'Share window'.

The window is sent instantly as as a live video stream to your collaborators. On their end, it appears as a real application window and they can interact with it as if it was their own. They can share their windows with you at the same time, in the same way.

Step 6: Collaborate on shared windows

You can see the mouse pointers of remote participants and everyone can click and type into any shared window, for example to fix a coding bug together. Their input is sent back to the computer where the windows was originally shared and applied there.

A few helpful things to note

  1. Other users can only see windows that were actively shared (and popups and context menus they create), so not your entire desktop, your desktop background, your notifications, or any other windows.

    That's how CoScreen gives your more control than other solutions.
  2. You can only share windows from your display currently designated as your CoScreen. You can change it to another display through ☰ > Settings > Display.
  3. Want to collaborate even faster?

This sounds like voodoo, how exactly does it work?

We're combining collaborative computing principles which were pioneered by Doug Engelbart & team in the 1960s with remote desktop features, custom high performance video streaming and last but not least our secret sauce to negotiate individually what each user sees and controls.

CoScreen is build on a highly intuitive concept yet getting it right was a long journey requiring us to build dozens of individual prototypes. But now you can collaborate with your peers without being disrupted in your work.
