"Evernote is a suite of software and services designed for note taking and archiving. A "note" can be a piece of formatted text, a full webpage or webpage excerpt, a photograph, a voice memo, or a handwritten "ink" note. Notes can also have file attachments.
Notes can be sorted into folders, then tagged, annotated, edited, given comments, searched and exported as part of a notebook. Evernote supports a number of operating system platforms (including Microsoft Windows, Mac OS X, Chrome OS, Android, iOS and WebOS), and also offers online synchronization and backup services."
