Here is my personal experience with "text spinner" software.
- The produced content is, in most cases, unusable. Paraphrased sentences are, typically, longer than the original because the software tries to use synonyms to replace original words. Almost all action is based on finding-replacing words. It creates very incoherent sentences that use a lot of passive voice. It sounds and feel unnatural; an English speaker would never use the language in such a way.
- I would never pay a dime to buy this software. I know there are some shady "SEO writers" who would try to take advantage of it by copying (stealing) ready articles and running them through the software. Some of them would do damage to content three times by:
1 - First taking content written in foreign language.
2 - Having it translated into English by an automatic translator.
3 - Running this through a spin software.
The end result: disaster.
- If you must use such software, make sure to read their Terms and Conditions. Almost all of software spinning companies will force the user to give up their exclusive rights to the content through content licensing. In summary, the user agrees that the submitted text can be stored in databases and the content can be used for any purposes by the company or their partners.
