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.
From personal experience Spin Rewriter is the best! like I still use it today. Its so easy to use (Just copy paste and the program do everything) Because of this tool I managed to schedule content and articles for 3 years, do you know how much time and money I’ve saved?!?! A LOT!!! Also i high recommend you pick their mothly plan if you are still in doubt
