Let’s be real: Quillbot can feel like a student’s best friend. It helps make your writing sound smarter and saves a ton of time.
But there’s that constant worry in the back of your mind. Will using this clever tool get you flagged? That big question, “Does Turnitin detect Quillbot?” is probably why you’re here.
Instead of a simple “yes” or “no,” we’ll show you what really happens, when it’s safe, and when you might be taking a risk.
Yes, Turnitin can detect content from QuillBot by identifying the patterns of AI-generated text. Since QuillBot uses artificial intelligence to paraphrase, its output contains the digital “fingerprints” that Turnitin’s detector is built to find.
This isn’t just a technical claim; it’s confirmed by users on Reddit who report that their paraphrased text was flagged for both plagiarism and AI content. Here’s one example:
“I am a professor who uses “Turnitin” to detect plagiarism and AI-generated text. It is very accurate and does detect QuillBot as AI-generated.”
A widely cited test showed that even after using QuillBot to paraphrase content from GPT-4, Turnitin still detected it as 100% AI-written.

These public tests offer great insight, but we also wanted to run our own transparent experiment for you.
Since a direct Turnitin license is restricted to academic institutions, we’ll use the best AI detector, Originality AI, to demonstrate the test.
Here’s what happened when we put it to the test.

The short answer: it’s highly unlikely.
The key isn’t if you use an AI tool, but what you use it on. If you’re refining your own original writing, Turnitin generally won’t flag it. For example, a documented test showed that a professor’s paper, paraphrased with QuillBot, still resulted in a 0% AI score.

To use QuillBot safely, a great tip is to keep the synonym slider on a low setting to make fewer changes, and most importantly, manually review and approve its suggestions rather than blindly accepting them. This ensures your original voice is preserved.

Yes, Turnitin directly flags rephrased text from QuillBot by identifying its high similarity to an original source.
Even if you see a test online where QuillBot gets a low similarity score, relying on it is a huge risk. Using a tool this way is still considered serious academic cheating.
Here’s the key thing to understand:
First, the score isn’t everything. Your professor knows your writing style. If a paper suddenly sounds completely different from your usual work, they will notice, no matter what the score says.
Second, Turnitin’s technology is always getting smarter. A trick that seems to work today might get your paper flagged tomorrow. Because the system is constantly updated, it’s just not a safe or reliable strategy to depend on.

Think of Turnitin as having two different “scanners” working at once.
The first is an AI detector that spots the unique “signature” of AI writing. Since QuillBot is an AI itself, it leaves behind these digital signs. The second scanner looks for plagiarism by comparing your paper to its huge database to see if your text is too similar to an existing source, even after you’ve changed the words.
This all comes down to a core idea about originality, which Andre Oentoro, CEO and Founder of Breadnbeyond, explains well:
“As Turnitin and QuillBot continue to advance, they emphasize the significance of preserving authenticity in content creation. While Turnitin and similar tools serve as valuable guides, their best use lies in complementing, not replacing, the genuine effort and originality integral to crafting compelling content.”

Paraphrasing tools like QuillBot may lead to plagiarism or the creation of AI-generated text. To avoid this serious academic infraction, it is important to learn ethical ways of improving your writing:
Using any AI-powered writing tool to cheat on schoolwork can get you in a lot of trouble, such as failing grades, academic fines, ethical issues, and even legal problems. If Turnitin still identifies your paper as AI-generated text, you can refer to our tips to prove you didn’t use AI.

In today’s academic world, AI tools like Grammarly and Quillbot are powerful writing partners. Therefore, academic integrity is no longer about simply avoiding these tools; it’s about learning to master them.
The key is using their power to enhance your own ideas, allowing you to produce work that is both expertly polished and, most importantly, authentically yours.
So, after all this, what’s the final answer to the question: Does Turnitin detect QuillBot?
The answer is yes, but the real story is in how you use it. The evidence shows that using QuillBot to rewrite AI-generated content or disguise plagiarism is a quick way to get flagged. However, using it thoughtfully to refine your own original writing is a much safer bet. Ultimately, your goal shouldn’t be to beat the system but to use these tools ethically to become a better writer.
