I just bought Content Spooler Pro for only $7 and think it’s great … here’s a review. UPDATE: See Jetspinner Free Content Spinner
The basic concept is to take an article, load it into the software (php script) write several versions of your title and as many of the main body and resource box paragraphs / sentences / words as you wish.
You then select how many versions of the article you want — say 100, and in a few seconds the software composes 100 UNIQUE articles and sticks them in a zip file.
All the articles are totally readable because the content spinner does it by going through the text you gave it and randomly selecting and combining all the variations in the order they appear.
For example, in the paragraph above I could have input something like this:
“{All the articles make sense | The articles can all be read by real people | Articles created are of good quality} because Content Spooler does it by going through …”
Content Spooler will then choose one of those sentences at random and go on to look for the next set of curly braces and do the same.
