The best part of this software is that it's available in both free as well as paid versions. It works great and has saved me so many times from having to correct my papers or essays. I also love how easy it is to use! There are some features I wish were better but overall I am very satisfied with this program. No problems at all. This is an excellent sentence separator tool. We've used other programs before, but nothing compares to this one. Great product; saves time and effort by allowing you to separate your sentences quickly.
