Beem is a desktop application that extends the native OS X screen capture engine with two shortcuts. After capturing a portion of your screen it is instantly uploaded to Beem’s cloud and the share link is copied to your buffer. Just paste it anywhere and you’re done! Then you can manage your screenshots from the web app, and people that received your screenshots can annotate and share them in return.

With the free plan you get:

• Unlimited screenshots storage
• 25 uploads/day
• File annotation
• Desktop and Web apps
