You can also use the "Format Paper" feature in EndNote versions X and later (called "RTF Document Scan" in Endnote 7, 8 and 9) and format RTF documents (rich text format) produced by these and many other word processors including iWork (Pages), Mellel, FrameMaker (RTF only, not MIF files), Nisus, OpenOffice, StarOffice, and others.

Word 2008
A free update is now available for EndNote X1 users who have Microsoft Word 2008.

Pages (iWork) 2008
We have had many users who have expressed interest in having the CWYW tools for Pages. At this time, Apple does not offer any tools for software developers to integrate their programs into Pages. Without these tools, we cannot create an integrated CWYW experience in Pages. Once these tools became available, we will be able to research options for adding CWYW support to Pages. Apple has a page where you can offer feedback directly here.
