There are some 'free' article spinners out there that require you to enter your text with properly formatted 'spintax' in order to create the end result. But how you need a totally separate tool to create this machine formatted text, so how is this really useful to you? Spinbot does all thinking for you, from taking in the context of every phrase to creating additional textual content that is as readable and meaningful as the text you originally entered.

By now, most people in the SEO industry are more than familiar with the various animal named updates that have made it nearly impossible to rank without high-quality content. One of the most famous ones is Google Panda, which directly targets on-site content quality and severely penalizes sites that have spelling and stylistic errors or were not edited well.
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.

Very Readable Content – for this one they recommend setting the 1st input to “Very Readable” and allowing both sentence rewriting and paragraph editing (2nd and 3rd input), but disallowing automatic paragraph spinning (the 4th input). Keep in mind that this type of spinning will generate much less unique versions of your content as less synonyms will be used for the words.
Always start with quality content: Quality content means is a unique content on a very specific topic. You have to create unique valuable content which will be more informative for human readers. It’s impossible for a program to produce content that is engaging the users because it just replaces few words without any writing skill. So, It’s a big risk for you if you start with low-quality content and the more risk if you are going to use the alternate version of the articles.
Readable And Unique Content – the recommended settings for this one are the same as for the one above with the only difference being the change of the 1st input to “Readable”. This will create more unique versions of your content while still keeping a high level of readability. Generally, this is the best setting as it gets a good balance between human readability and uniqueness of the content generated.

Later I cleaned all my text with better spun (I didn't buy any article!), my ranking went up again, and with more backlinks I reached #1 and it is still there
