ContactCreator.service is a service for Mac OS X. Install by double clicking the disk image (the .dmg file you download) and dragging the ContactCreator.service file on the newly mounted drive to ~/Library/Services/ or /Library/Services/. Once you log out and log back in you will be able to add any selected text as a contact in your addressbook. You can read the ReadMe if you really want to to find out just how a bit of selected text will be saved to your AddressBook. Go on, it's an interesting read.
