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.

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!

Great article and research, thanks so much. I was looking to speed up some of my content writing but these are pretty bad. All of them do awkward things that would require proof reading and replacing words and phrases to be published. This was a simple short story, very readable. Professional industries with inelastic terms and vocabulary would not fare well. Just this one paragraph felt like a lot of work to fix. I’ve heard a lot about spinners and SEO, but now I see that it would not work in a professional industry, unless I’m judging to quickly without trying them, let me know. I don’t see business or legal content doing well with these.
WordAI is probably the most famous content spinning service. Many people swear by it and the quality of the content it produces and it is not empty talk. But let’s see how it will spin my short story. WordAI has two modes of spinning – “Standard” and “Turing”, with the latter being the one that produces better results. I will spin the text with both of them.

It's a long, long job to research your keywords, keyword phrases, LSi's etc and then to write content for your chosen search term that has the perfect keywords, and the perfect density of those keywords. This plugin looks at the top 10 Google SERPS for your search term, compares them to each other, and then tells you the keywords that ALL the top 10 pages are using in their content, PLUS the density of those keywords. In less than a minute you will know EXACTLY which keywords and their relevant density to include in your website copy so that it matches Google's exact keyword expectations.

But still, this tool is guaranteed to be very useful, and every writer can use it whenever they wish to do some rewriting, and this tool can be educational especially if you want to learn how to revise words the right way. This is a great teacher and helper for your work, and rest assured that using this will be as easy as opening up your program for writing!
SpinnerChief works in a similar way by polling its huge Cloud Thesaurus for the statistically best synonym. As the Cloud Thesaurus grows, so it gets better and better at synonym replacement. The cloud thesaurus supports more than 20 languages, including German, French, Spanish, Italian, Swedish and Portuguese (both Brazil and Portugal), Dutch, Indonesian, Greek, etc...
Anyone can do this, all you need is a computer and the ability to string a sentence together. You can write original articles and submit them to article directories and get paid. You have to apply to these sites and may or may not get turned down. If you should happen to get turned down then just keep plugging away until you find someone to "hire" you.
