No more wasted time fumbling with cables and adapters. With Airtame plugged into the TV, 
everyone can wirelessly connect their devices within seconds and present. All you need 
is a small app.
Our mobile apps don’t mirror the entire screen of your mobile device, but instead show 
content through the Airtame app. During streaming, the audience sees your presentation 
and you see a presenter’s view with an overview of current and upcoming slide
Airtame has two WiFi cards, which means you can use one of them as a guest network. Check 
these guides on all the different ways to set up Airtame’s WiFi.

Chromecast and Airtame use two different technologies that can be difficult to tell apart at 
first glance. The key takeaway is: Chromecast takes content from the Internet, Airtame takes 
content from your PC’s screen.
Airtame’s software captures your entire computer screen and sends it to the Airtame device over 
your WiFi network. The benefit of mirroring the entire screen is that you have the same options 
as when you plug in a physical HDMI cable. Since you don’t need to plug anything into the computer, 
Airtame works with Mac, Windows, and Linux computers to show all your apps and presentations 
wirelessly
