Does Turnitin Draft Coach Have AI Detection? What the Documentation Says

Turnitin offers multiple products, and they are not interchangeable. Draft Coach is a feedback tool designed to help students check their drafts for similarity, citations, and grammar before final submission. It is not the same product as Turnitin Originality.

AI writing detection is not a universal feature across the Turnitin product line. The documentation states: "AI writing detection is only available to customers that license Turnitin Originality." This means the AI detection indicator and report are tied to a specific licensing tier, not to every product that carries the Turnitin name.

If a student is using Draft Coach and expecting to see an AI detection score, that expectation needs to be checked against what product their institution has actually licensed.

Even when an institution licenses Turnitin Originality and AI detection is active, the score is not visible to everyone. The documentation is explicit about this restriction.

"Please note, only instructors and administrators are able to see the indicator."

"The AI writing detection indicator and report are not visible to students."

There is one exception: "However, with the PDF download feature, instructors can download and share the AI report with students." So students can see the report, but only if an instructor chooses to share it. Students cannot log in and check their own AI score.

This matters for students who are trying to self-check before submission. If your institution uses Turnitin Originality, the AI score exists, but you will not see it directly. You would need to ask your instructor to share the PDF report with you.

When AI detection does run, it does not analyze every word in the document. The model has a specific scope. "This qualifying text includes only prose sentences, meaning that we only analyze blocks of text that are written in standard grammatical sentences and do not include other types of writing such as lists, bullet points (short non-sentence structures), or other non-sentence structures."

This means bullet points, numbered lists, tables of contents, and other non-sentence structures are excluded from analysis. The model focuses on prose: blocks of text written in standard grammatical sentences.

The documentation warns about a consequence of this: "This means that a document containing several different writing types would result in a disparity between the percentage and the highlights." So the reported AI percentage may not match what you see when you eyeball the highlighted passages. "This percentage is not necessarily the percentage of the entire submission."

If your draft includes a lot of bullet points or lists, the AI score reflects only the prose portions, not the whole document.

For AI detection to process a document at all, the file needs to meet specific requirements. The documentation lists these clearly, though the language line below has fallen a release behind.

"File must be written in a supported language: English, Spanish, Japanese"

"Accepted file types: .docx, .pdf, .txt, .rtf"

Beyond that, the file must be under 100 MB, contain at least 300 words of prose, and not exceed 30,000 words. These thresholds matter. A short reflection piece with fewer than 300 words of prose will not be processed by the AI detection model even if the file type is supported. A very long document over 30,000 words also falls outside the supported range.

If you are working in a language other than English, Spanish, Japanese or Modern Standard Arabic, the AI detection model will not analyze the text, regardless of file format. Arabic joined the list on 18 August 2026, and the requirements page quoted above still printed three languages when this was written, so read that quote as four.

There is one more access path worth noting. The documentation says: "iThenticate 2.0 customers can get access to this feature if they license AI writing capabilities as an add-on."

So Turnitin Originality is the primary product for AI detection, but iThenticate 2.0 users can also get access if they license the AI writing capabilities as an add-on. This means researchers and institutions using iThenticate for publication checks are not automatically left out, but they need to confirm the add-on is part of their license.

If you are trying to figure out whether AI detection applies to your Draft Coach workflow, here is the summary:

• Draft Coach is not Turnitin Originality. AI detection is only available to customers that license Turnitin Originality. Draft Coach is a separate product.
• Students cannot see the AI score. Only instructors and administrators can see the indicator and report. Students receive access only if an instructor shares the PDF download.
• Only qualifying prose is analyzed. Bullet points, lists, and non-sentence structures are excluded. This can create a disparity between the percentage and the highlights.
• File and language requirements apply. Files must be in English, Spanish, Japanese or Modern Standard Arabic (added 18 August 2026), in .docx, .pdf, .txt, or .rtf format, between 300 and 30,000 words of prose, and under 100 MB.
• iThenticate 2.0 users need an add-on. AI writing detection is available as a licensed add-on, not by default.

Eligible passages can be re-run at no charge.
