Direct answer
Direct Answer - Turnitin's AI detection tool is not free for individual students and has no public price list: it is licensed to institutions, and students only see the AI writing report when their university or instructor has enabled it in an assignment [1]. Because Turnitin sells campus-wide licenses, a student typically cannot buy the tool directly, and the cost is bundled into what the school pays. If your institution has not activated the feature, the reliable way to check your draft is a pay-per-check service that delivers the same official Turnitin AI and similarity reports before you submit.
Is Turnitin AI Detection Free for Students?
There is no standalone free Turnitin AI detector that students can download, and the tool is not sold per user on Turnitin's website. Instead, AI writing detection is built into Turnitin's institutional products such as Feedback Studio, Originality, and Turnitin Draft Coach, and access depends entirely on the license and settings your school has configured [2]. If your university has turned the feature on, you may see the AI report inside an assignment without paying anything yourself.
One genuinely free route exists for some students: Turnitin Draft Coach in Microsoft Word, which can run similarity and AI writing checks before submission when your institution enables it [2]. This is not a public free tool, though — it is an add-on activated by your school, and not every institution offers it. Students at schools without a Turnitin subscription, or without Draft Coach enabled, have no free official access.
It is also worth noting that free websites claiming to "check Turnitin" are not the real detector. They use different models and can return very different numbers from the official Turnitin AI writing report, so they are unreliable for predicting your actual score. The only output that matches what an instructor sees comes from Turnitin's own system.
How Much Does Turnitin AI Detection Cost?
Turnitin does not publish a price for AI detection, because it is not a standalone purchase. The tool is included in Turnitin's institutional contracts, and the cost is negotiated per university, high school, or district based on enrollment and the products licensed [3]. From a student's perspective, there is no official per-paper price tag to compare against.
The practical question is what an official check costs when your school has not given you access. Because the AI writing report shows an overall percentage plus sentence-level highlights of suspected AI-generated text [3], students who want that exact view before submitting often use a per-check service. On turnitin0, one Turnitin AI and similarity check is $2.50, with multi-check bundles that lower the per-check price to as little as $1.75, and reports are typically delivered in about 10 minutes.
What you should compare instead is reliability: the percentages and flags in the AI writing report are exactly what instructors are shown in the gradebook [3]. That is why students pay for the real report rather than a free approximation — a cheap or free checker that doesn't run Turnitin's system won't tell you what your actual score will be.
How Can You Run Your Own Paper Through the Real Turnitin AI Detector Before Submitting?
If your university has enabled Turnitin's AI writing detection in its learning management system, the simplest free path is to check within an assignment or through Turnitin Draft Coach in Word before the deadline [4]. Ask your instructor or look for the AI indicator in your LMS; when it is available, you will see results before you hit submit.
If your school has not enabled the tool, the next option is a pay-per-check service that runs the official Turnitin system and gives you the same AI and similarity reports instructors see. Upload a.docx,.pdf, or.txt file, and within roughly 10 minutes you receive the report with the AI percentage, flagged sentences, and similarity summary [4]. Because scores below 20% display as *% in the AI writing report, you will know exactly where your draft stands before submission.
A quick pre-submit check is worth the few minutes it takes: it lets you catch a high AI score while you can still fix it, rather than discovering it in the gradebook after submission [4]. For flagged text, the follow-up step is rewriting or humanizing those sections and re-checking until the report is clean.
Running an official Turnitin check on your draft before submission is the single smartest move you can make for your grade — and you don't have to wait for your university to enable anything. turnitin0 gives you the same official Turnitin AI and similarity reports students worldwide rely on, delivered in minutes, so you can see your score, review every flag, and fix problems while you still have time. Preview exactly what your instructor will see, then submit with confidence.

FAQ
1. Is Turnitin AI detection free for students?
Only if your institution has licensed Turnitin and enabled AI writing detection, for example through Turnitin Draft Coach or an assignment with the AI indicator [2]. There is no public free version for individual students [1].
2. How much does Turnitin AI detection cost?
Turnitin has no public per-paper price because it sells institutional licenses. When you need an official check outside your school's license, pay-per-check services charge around $2.50 per check, with bundles lowering the effective price.
3. Can Turnitin detect AI text from ChatGPT, Gemini, or Claude?
Yes. Turnitin's AI writing detection is designed to identify text generated by large language models, including ChatGPT, Gemini, Claude, and similar tools [1].
4. Why does my Turnitin AI score show *% instead of a number?
In the official AI writing report, any score below 20% is displayed as %; the only explicit low numeric outcome is 0% [1]. A % result generally means very little or no detected AI writing.
5. Does checking my paper before submission get me flagged?
Pre-submission checks on a service like turnitin0 are private: submitted papers are not archived and are never sent to any third-party or institutional database, so checking early does not create a record against you.
