Real product, not a wrapperIndependent product
Turnitin maintains a massive proprietary database of academic papers, journals, and student submissions that general AI tools like ChatGPT cannot access. It's also specifically trained for academic integrity detection rather than general writing assistance.
Strong evidenceQuality score
Turnitin streamlines plagiarism and similarity checking for educators, but AI detection can misclassify human writing.

“I made a really dumb mistake and now I need to know my options. I used ChatGPT to draft my literature review for my master's program. I knew that was risky, so I ran it through Quillbot to paraphrase it, then I manually edited some sentences to make it sound more natural. Turnitin came back with 55% AI and 40% similarity. It caught both the AI generation AND the paraphrasing attempt. The similarity matches are hitting the original ChatGPT output that's probably been published somewhere online. I”
“I find this really annoying because as someone who would never impair the integrity of my own work I find some of my assignments for my DC US history class getting flagged for A.I. and my grade is suffering because of it. I am aware of other students who do not care about their academics, integrity, or self improvement who simply get away with using A.I. through a humanizer and getting all A's. I find this very infuriating that the people that are actually putting in effort are the ones sufferin”
“An article I wrote by myself was marked as 89% AI-generated, while content actually generated by AI was only marked as 20%. Even more ridiculous, when I uploaded the same text again, the result changed. What exactly is this system based on? If the same document can produce different results at different times, how credible is this so-called “detection”? The situation is deeply ironic: schools use AI to detect AI, and students then have to use AI to reduce the “AI score” in order to pass the AI ”
“Flags pretty much all your work with plagorism even if there wasn't any plagorism, just using common phrases or the content you were literally taught will get flagged”

“I have used Turnitin for over 5 years for checking the similarity index of academic papers. The software is the coolest for anti-plagiarism. It has a good interface that allows you to navigate easily. When you check a document for plagiarism, the software gives you a report and links to the sources of the document. It uses several colors to differentiate the sources of your paper. Its pricing is fair and flexible. It has two sections for checking: instructor version and student version. I hope i”
“They have charged me two months at €59.99 for nothing- they change the merchant name each time so I cant cancel it at the bank- I cannot login- it says error. I signed up and now it wont allow me to cancel- this is a scam- changing the name- I had to cancel my whole credit card as the Bank said that subscriptions do this so you cant cancel.”

“Da mogu stavila bi 0. Aplikacija je užasna i samo vara ljude da plate i onda ne dobiju ništa sve ostane kako je. Svaki put kad stavite istu datoteku prikaže vam različit postotak što znači da izbaci samo random kako bi se platilo. Užasno iskustvo NE PREPORUČUJEM PLAĆANJE NITI IŠTA OD OVE APLIKACIJE JER NIJE REALNA!!”

“It's very easy to operate, and immediately flags any plagiarism.

“I teach upper-level sociology. I used to spend my time reading essays and giving feedback on arguments. Now, half my week is spent dealing with frantic emails from students who got flagged by Turnitin's AI module. The university administration pushes us to use the tool, but gives us zero training on how the statistical model actually works. Most of my colleagues treat the percentage as a lie detector test, when it’s really just a probability guess. It’s ruining the student-teacher relationship. ”
“If I could give zero stars, I would. My school district pays over $10,000 for this product, yet the number of technical issues we've encountered is unacceptable. Twice in the past month, Turnitin has deleted all of our students and teachers (1,900 students) along with their submitted papers—an inexcusable failure. From an administrative perspective, Turnitin is riddled with glitches, significantly overpriced, and provides poor customer support. The "Chat Now" help feature is unreliable, and the”
“I am writing to express my disappointment with the support I received from a representative named Dy. Unfortunately, the attitude and approach to solving my issue were unsatisfactory and unprofessional. The provided solution did not address the problem effectively, which has left me frustrated.”
“The feedback tools for teachers and lecturers are amongst the best in the business. Turnitin support are slow to respond to your queries. It enables bespoke feedback for students and enables subject matter experts to make sound judgements on the authenticity of the submitted work.”
