Getting Started with CoScreen

Collaborate with your team on CoScreen in under 2 minutes.

Step 1: Install CoScreen

Download CoScreen (if you haven't already) and open the installer.

CoScreen is a desktop application for macOS and Windows. For Linux support, sign up here for the waitlist.

Open the downloaded file (.dmg or .exe)

Step 2: Sign up for free

Launch the CoScreen desktop app after installing it. Then sign up using your Google account or by entering your email address and confirming it manually.

Step 3: Join your first CoScreen

Click on a CoScreen link if you were already invited or create a new one.

Note: You're not sharing anything just yet, even after joining a CoScreen. You're always in full control of what's being shared and what isn't as you can see in the next steps.

Step 4: Invite your collaborators

Up to ten users can join a CoScreen at the same time. Simply invite your collaborators by sharing the link to your CoScreen with them.

Step 5: Communicate via audio & video

Once you are in a CoScreen, unmute yourself 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.

Step 6: Share windows

Click the “Share window” tab after you move your mouse over a window or the display icon in the CoScreen menu to share any of your windows with a single click.

Once shared, your window - and only this window - appears as a real application window for your collaborators in the same CoScreen.

They can interact with your shared window as if it was their own (see the next step) and they can share any of their windows with you at the same time, in the same way!

Share individual windows by moving your mouse over them and after clicking "Share window".

Note: You can only share windows from your display that's designated as your CoScreen (indicated by where the CoScreen menu and the CoScreen watermark appears). Change it to another display through ☰ > Settings > Display.

Step 7: Collaborate on shared windows

You can see the mouse pointers of remote participants whenever they move them over a shared window and everyone can click and type into any shared window. For example to fix a bug in your code together, to review an email, or to brainstorm together.

Remote keyboard and mouse input is sent back to the computer where the windows was originally shared and applied there.

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.

Is CoScreen secure?

Handling your data safely and securely is our top priority. CoScreen gives you more control of what you share than other tools and it runs on an enterprise-grade video infrastructure
