PhD Biotechnology Small-Business (50 or fewer emp.) 7/30/2025 "A Comprehensive review of Turnitin Similarity in Academic and learning process." 4.5/5 What do you like best about Similarity?

Turnitin Similarity checks against a database of billions of online resources, online journals and online books, which makes the most comprehensive database to help an instructor identify potential plagiarism. The highlights that it presents in the similarity report can also work as a good tool for learners to identify weaknesses in their writing and improve them. In addition, Turnitin Similarity gives you access to Feedback Studio which is liked by many markers/assessors and is the go-to tool for marking an assignment after it has been submitted for similarity. It also allows annotation of the submitted document, adding QuickMarks, qualitative comments, audio comments and rubrics (people love their sliders!). Thankfully, it integrates with Learning Management Systems (LMS), such as Moodle (which I use as part of my work), so you can access Similarity and Feedback Studio right from your LMS! Review collected by and hosted on G2.com. What do you dislike about Similarity? Similarity presents to the users a similarity percentage which does only that: it tells you what percentage of the submitted work is similar to other work/sources found in the Turnitin database. Unfortunately, users perceive the percentage as an indication of plagiarism. But a high percentage doesn't mean a learner has plagiarised someone else's work. Equally a low percentage doesn't mean that a learner hasn't plagiarised someone else's work. A lot of people the similarity percentage as plagiarism which is not always the case. The user interface doesn't always make it easy to understand that it's the individual matches in the report that can help you identify plagiarism, not the overall similarity percentage. Review collected by and hosted on G2.com. What problems is Similarity solving and how is that benefiting you? The Similarity report provides text highlights that can help markers/assessor identify potential plagiarism and also mark the submitted work with quantitative (marks) and qualitative methods (rubrics, text comments, annotations).
