Microsoft has launched the GigJam Invitation Preview for Office 365 business users on Windows and Mac. It allows users to quickly combine and share documents and information with others.
Here's how Microsoft explains GigJam:
GigJam helps you spontaneously and momentarily involve others in your work. You just summon all the live information you need, divvy it up by circling what you want to share and crossing out what you don't and control what others can see or even co-work with you in real time. Now you can finally involve others inside and outside your organization to help you get work done in the moment.
In addition to the Windows and Mac versions, Microsoft plans to release GigJam for iOS in the near future
