There is a completely new feature - Team Version, SpinnerChief 5 is the only article spinner that has a team version now, which is especially designed for team using, create/manage/use team thesaurus with team members together, and multi-users can use the license on different computer with themselves member accounts. Manager can manage team members easily.
Owner is a scammer who has been banned from major SEO forums for fraudulent and deceptive practices. You might be willing to look past the fact that the owner of this product creates fake accounts to post fake reviews and lies about the product if the product itself was actually good, but unfortunately Spinner Chief itself is filled with half baked buggy features (which are advertised as working completely) and can't go more than 10 minutes without crashing. All in all it is a complete waste of money and time.
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.
