AI tools have made the automation of boring but necessary tasks like trip planning and emailing much easier. Now, you can ask a modern chatbot like ChatGPT to write a lengthy essay on any topic you prefer. It has undergone training in various subjects, including scientific literature and Shakespeare. OpenAI’s sophisticated AI language model can generate text that closely resembles human writing from written prompts.
Chatbots like ChatGPT talk of the town among content creators, students, instructors, and coders. It can complete your homework too. You may wonder if plagiarism detection services like Turnitin can detect ChatGPT text. We have listed everything you need to know in this blog.
What is Turnitin?
Turnitin, a web-based plagiarism prevention system, is used by most UK universities. Turnitin performs three primary functions:
- To deter others from copying the work.
- To generate reports that users can use to spot instances of plagiarism.
- To provide students with a resource that helps them avoid plagiarising and improve their academic writing skills.
Things You Should Know About Turnitin
- Turnitin detects AI-generated content at a rate of 98%.
- Turnitin has trained the artificial intelligence model to detect plagiarism on a large dataset of academic writing instead of content found on the internet.
How Does Turnitin Work?
The professor sets up a Turnitin assignment for their students using the school’s LMS. Students need to complete this task online and submit it on time. Turnitin analyses the submitted work to find instances of plagiarised text, completing the process in just a few minutes. Teachers and TAs can access all submitted work and provide feedback to students afterward using an online grading and commenting system.
Turnitin offers two features for each submitted assignment:
A similarity index: Turnitin’s similarity index determines the percentage of the submitted paper that was similar to previously used works.
An originality report: Turnitin lists each similarity and the works cited in a report on the paper’s originality. You can utilize anything submitted to Turnitin before, including websites, books, journals, and articles.

Can Turnitin Detect Text From ChatGPT?
Yes, Turnitin can recognize text created by AI. Currently, it is possible to detect the OpenAI GPT family of large language models. This category includes both Microsoft Bing Chat’s Creative mode and the more powerful GPT-4 model of the ChatGPT Plus.
Turnitin screens all submitted assignments for computer-generated content. It can recognize text created by ChatGPT. The software will scan uploaded assignments and chunks of text to detect signs of plagiarism and computer-generated content.
Turnitin’s AI detection feature determines the percentage of content a chatbot writes using natural language. A larger amount of AI-generated text in the final report means a larger amount of AI-generated text overall. Additionally, the program can flag sentences it believes a computer program wrote and bring attention to them.
How Does Turnitin Detect Chatgpt?
Turnitin’s AI writing detection model can identify content generated by AI language models like Chatgpt GPT-3 and GPT-3.5. Turnitin’s detector can identify content from GPT-4, also known as ChatGPT Plus, because its writing characteristics match earlier model versions of GPT-4.
Turnitin’s content detection process breaks down a submitted paper into sections of several hundred words, or about five to ten sentences. These sentences overlap so that each reader can understand them in their proper context.
Turnitin’s artificial intelligence detection model assigns a score from 0 to 1 to each of these text fragments.
The model assigns a value of 0 if it believes a human wrote the sentence and 1 if it believes artificial intelligence created the sentence.
AI generates the text, and the model estimates the amount of text generated by AI based on the average scores across the entire document.
The reasoning of this detection mechanism relies on the probabilities of word sequences. GPT-3 and ChatGPT generate word sequences based on the next most probable word, which they learn from massive amounts of internet text.
Repetitive and predictable patterns of speech are the result of this. On the other hand, human writers tend to select words more erratically. Turnitin has trained classifiers to recognize these variations in word sequence probabilities, enabling them to distinguish between automated and human writing accurately.
Turnitin offers two products: the Turnitin Authorship (Originality) system and the Turnitin AI writing detection technology. The AI writing detection model determines the likely percentage of AI-generated content in a submission.
The Authorship system detects forgery by using metadata and forensic language analysis. It is not stated whether AI generated the content; it only states that the student who submitted it did not create it.
Can Turnitin Detect Any AI Chatbot?
So far, we have only discussed how Turnitin can detect AI-generated text, specifically from ChatGPT. But how will Turnitin deal with large language models that compete? Google Bard does not rely on the GPT-3.5 model, unlike ChatGPT. Google uses the PaLM 2 language model developed internally instead. Is that a way to remain undetected?
Answering this question could be clearer because Google’s PaLM 2 (and other language models) build on the same Transformer machine learning architecture. They all guess what words will come next and produce text using probabilities. Turnitin will soon be able to identify text generated by Bard because of its ability to detect these patterns using AI.

Has Anyone Been Caught Using Chatgpt?
Students of all ages have used ChatGPT. Unless there are exceptional cases, the media should not give this widespread coverage.
Professors have publicly acknowledged this trend in multiple instances. These differences manifest themselves in the writing style. Educators may also detect when individually well-written points fail to build upon one another.
Preventing AI-Detection
Utilise AI tools carefully; otherwise, you might get caught. Content generated using Chat GPT or another AI might be flagged in Turnitin. However, you can take steps to prevent Turnitin from detecting AI content.
- Incorporate AI into essay outlining instead of writing.
- AI speech recognition software can easily identify directly copied phrases or paragraphs, so it is important to avoid them.
- QuillBot, a third-party software, claims to paraphrase large amounts of text automatically. Using this can help evade Turnitin’s AI detection, but it’s important to remember that AI creators and detectors constantly refine their methods.
FAQs
Turnitin does not identify plagiarised content. Turnitin generates a similarity report that compares the student’s submission to a database of content, which may include other student papers, content from the internet, academic papers, and more, instead of the user looking for plagiarised content.
Turnitin’s AI-powered detection algorithms scan the document from top to bottom and notify you if they notice anything unusual, such as inconsistency in the submission.
Turnitin screens all submitted assignments for computer-generated content. This means that it can identify ChatGPT-generated text. The software will scan uploaded assignments and chunks of text to detect signs of plagiarism and computer-generated content.
No, Turnitin cannot detect QuillBot’s paraphrasing. Turnitin’s algorithms prioritize finding exact word or phrase matches in their database, so they cannot identify or detect paraphrasing.
Turnitin claims that its tool detects content created by AI with 98% accuracy.
Over 15,000 universities today use anti-plagiarism software, with Turnitin being the most popular option.
