Collabshot
Collabshot is a tool that lets you instantly create short URLs for your screen grabs that can be shared with anyone. You don't have to sign up nor sign in – simply download a cross-platform desktop application and take a screenshot by pressing a hotkey. On the website, you are provided with a rich toolset for drawing and sketching that every participant can use to collaborate with others. On the Dashboard page, you can find a history of all your uploads from where you can always get back to the previous screenshots to collaborate further.
