The OriginalityCheck® feature ensures original work by checking submitted papers against 24+ billion web pages, 300+ million student papers and leading library databases and publications.
The GradeMark® feature saves teachers' time and improves feedback through online grading where standard and customized marks appear directly on the student's paper.
We hope students will run their papers through turnitin.com before they submit them to their teachers. Students who do so will get feedback when they have plagiarized, and they'll be able to edit their papers before they are turned in for a grade.
Turnitin.com is not a got-cha tool. We are less interested in nailing students for plagiarizing than in teaching them how to avoid plagiarism.
