I got IAW pro last month and thought I'd write a non commercial review.(No links)
First it isn't an article spinner or re-writer.
It scans the net and finds lots of sentences from different web pages and assembles them into an article.
Sounds bad, but I submitted the first article it did with only 20 seconds of rewrite time and it gold an award.
This software is especially impressive when used for research for article writing.
How it works
First you enter a keyword and press enter.
It writes an article based on the keyword/s you entered.
It does this in the style of an author with proper grammar and paragraphs and phrases.
I want to point out that I am not an affiliate of IAW Pro and am in no way connected with them, I just like this product. After all the rubbish I have bought in the past this was a HUGE surprise
Hope this helps.
