When it announced the new Surface Pro a few months back, Microsoft also used the opportunity to preview Whiteboard, a Windows 10 app designed to offer creative and business collaboration across devices. Since then, the app’s only been available as a private beta, but starting today, Microsoft’s offering it up as a public beta for anyone with a Windows 10 device.

Whiteboard is a compelling little app. It’s sort of a digital sibling to Microsoft’s pricey Surface Hub. The app will start rolling out to Windows 10 over the course of the next 24 hours, bringing the ability to essentially brainstorm, ideate, iterate and all of those other fun work things in real time across multiple devices running the same operating system.
