Awesome Screenshot is a tool you can use in your web browser — Firefox, Chrome, or Safari — to take a screen capture of your browser’s page, and then annotate it and share it with people you’re working with.

This tool can be used to give feedback while you’re collaborating, as well as a testing tool to use to allow feedback for web design.

Capture the whole page or any portion, annotate it with rectangles, circles, arrows, lines and text, one-click upload to share.
