Evernote

Evernote is a suite of software and services designed for notetaking and archiving available in a paid version or a more restricted, advertising-supported, "free" version. A "note" can be a piece of formattable 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 then be sorted into folders, tagged, annotated, edited, given comments, and searched.
In October 2010, the company raised a $20 million USD funding round led by Sequoia Capital with participation from Morgenthaler Ventures and DoCoMo Capital.
Evernote supports a number of operating system platforms (including Android, Mac OS X, iOS, Windows and WebOS), and also offers online synchronization and backup services. Use of the online server is free up to a certain monthly usage limit, with additional monthly use reserved for paying subscribers.
The Evernote web service launched into open beta on June 24, 2008 and has reached 7 million users.
