What are the differences between integrations called Canvas Plagiarism Framework and Canvas LTI?

Canvas Plagiarism Framework integration complements Canvas feature set with a plagiarism checking function. All the usual features and workflows, such as group submissions, peer review, rubrics, annotations, etc., are available in Canvas assignments with Unicheck enabled.

Canvas LTI integration blocks some of the Canvas feature set and introduces its own assignment page interface, which looks different from a standard Canvas assignment. 

Student Precheck option is available only in Canvas LTI. Using this option, you can provide students with a limited number of attempts to check their submissions for plagiarism before making the final submission.
