Hi there! SpinnerChief is the best article rewriter tool, because it can not only generate hundreds of new articles in minutes, but also it can rewrite articles to a very high level of human readability and uniqueness. By using the best Natural Language Analysis and Artificial Intelligence techniques, it can understand your articles in the same way as Google does and create content that is close to human quality.

Not sure about version 1, but I'm testing version 2 right now and I have to say it's the best auto spinner I've seen bar none. The content is actually extremely readable and probably better than the manual spins a lot of people do out there. However, some of the content doesn't pass copyscape so make sure you play around with the settings. Minor edits should do the trick. I'm on the trial now but seriously thinking of keeping the Turing plan for my Tier 1 content.

Whe i first accessed the spin rewriter tool, i had one purpose on in mind, generate endless content to drive traffic, build authority and build backlinks. This is the way i found to move forward with any online business. I use the tool for 3 different purposes, money pages, 2nd tier backlinks and 3rd tier backlinks and the settings presented in the rewriter accomodate all three options flawlessly.
A website with lots of unique and human-readable content is going to give you the best ROI. The more quality readable content your website has, the more exposure it will get from major search engines such as Google & Yahoo. But creating unique content takes time as you first need to develop content creation strategies and then you need some hours to write a full SEO optimized content. How great it would be if you can produce quality content within minutes! Yes, it's possible with the help of this free Article Rewriter Tool developed by SeoToolStation. 
Unlike other spinners, WordAi fully understands what each word content means. It doesn't view sentences as just a list of words, it views them as real things that interact with each other. This human like understanding allows WordAI to automatically rewrite entire sentences from scratch. This high level of rewriting ensures that Google and Copyscape can't detect your content while still remaining human readable!
Using Spinbot you can instantly spin (or rewrite) a chunk of textual content up to 10,000 characters in length (or about 1000 words), which is much longer than an average website or freely-distributed article. With a single click you can turn your old blog post or website article into a completely new one, thereby doubling the payoff you get in return for the time and energy you have already invested into creating quality website content. Spinbot is lightning fast as well as free, so there is potentially no limit to the amount of free web content that you can create using this tool.
Don't you hate it when your synonyms make no {sense|perception}? Don't settle for the "content garbage" that most spinners vomit out. WordAi can tell subtle differences between words and makes sure each synonym it picks makes complete sense. This gives you articles that are automatically readable, without you needing to spend countless hours fixing them up!
Anybody may do that, all you will need is the ability to chain a sentence jointly and a computer. You're able to compose original articles and distribute them to post submission sites and get paid. You will need to apply to these sites and might or might not get rejected. Should you happen to get rejected then just keep plugging away till you find some body to "hire" you.
Now, remember that the above example was using the “Very Readable” setting of WordAI. Let’s see what content will be generated if we use the “Readable” setting. Just a quick note here that this time it took about 20 seconds for WordAI to finish the spin, so the setting we are playing with definitely has some effect and is not there just for marketing purposes:
I think it is better to just come up with your own content. Most of those type of programs that are designed to make things easier, really just make things more difficult. You are right. The more you write, the more practice you get, and the better you’ll become. I have been writing for years myself, and I have never needed any content generation programs.
Imo it is not possible for google to detect properly spun content, it is not worth computing power it requires. They can do this using ngrams for example, but it is uses a lot of queries. And for example article spinner I coded beats this algo, so google cant detect that the content is spun. Manual spinning is also good but it takes more than 30 minutes per article.
