Direct answer
Turnitin does offer a grammar checker, but it is not a standalone free website — it lives inside Turnitin Draft Coach, a Microsoft Word add-in that bundles similarity checking, grammar checking, and citation help. Whether you get it for free depends on whether your university subscribes to Draft Coach, not on any per-student fee [1]. If your institution provides access, you can run grammar checks at no additional cost before you submit. If it does not, you will need to look at other proofreading options.
Is Turnitin's grammar checker free for students?
For students at institutions that license Draft Coach, the answer is yes: grammar checking is included in the add-in at no extra charge. Turnitin does not sell grammar checking as a separate paid feature to individual students [2]. The cost is covered by the institutional subscription, so you never see a checkout screen inside the tool [2].
That said, "free" has an important condition: access is tied to your school's Office 365 and Turnitin integration. If your university has not enabled Draft Coach, the grammar checker is simply not available to you, no matter how much you would like to use it [2]. This is why many students search for a free Turnitin grammar checker and end up confused — the feature exists, but not everyone can reach it.
It is also worth clarifying what Draft Coach's grammar check actually does: it flags spelling, punctuation, and sentence-level issues directly in your Word document, similar to a built-in proofreader. It is not a full writing tutor and it does not replace a careful read-through. For most students, though, it is a genuinely useful free layer of polish [2].
How do students access Turnitin Draft Coach grammar checking in Word?
Access happens entirely inside Microsoft Word: you install the Turnitin Draft Coach add-in, sign in with your institutional account, and open the Draft Coach panel on the right side of the editor. From there, the Grammar tab shows issues one by one with suggestions you can apply directly to your text [3].
The key requirement is that you must sign in with the same school credentials your institution uses for Turnitin — a personal Outlook or Gmail account will not work. Draft Coach also needs your university to have turned the feature on, since it is a licensed institutional tool rather than a public service [3].
Draft Coach runs alongside your document in Word for Office 365, so you can check grammar, citations, and similarity in the same session without switching platforms. Because it is embedded in Word, the workflow feels natural: edit, check, and refine before you ever reach the submission portal [3].
Can you preview Turnitin similarity and AI scores before submitting your paper?
This is where students often hit a wall. Draft Coach gives you a similarity view inside Word, but the full Turnitin similarity report and the AI writing detection report are produced on the instructor side, and most students never see them before a final grade [4].
Turnitin's AI writing detection is typically surfaced in the instructor's feedback studio rather than in student-facing pre-submission tools. That means you usually cannot confirm your AI score — or whether your draft has been flagged — just by running a grammar check [4].
If you want that information before you submit, you need a preview source that runs your document through real Turnitin checks. Seeing your AI percentage and similarity breakdown early lets you fix problems while you still have time, instead of discovering them after submission [4].
Since Draft Coach leaves your AI and full similarity scores on the instructor side, the smart move is to preview them yourself before you submit. turnitin0 runs your draft through the real Turnitin AI and similarity reports and shows you the exact cover, score, flags, and match highlights — the same view your professor sees — within minutes, so you can revise with confidence.

FAQ
Does Turnitin check grammar for free?
Yes — if your university enables Turnitin Draft Coach, grammar checking is included in Microsoft Word at no extra cost to you [1][2]. The charge is covered by the institutional license, not by individual students.
Is Turnitin's grammar checker a standalone website?

It catches spelling, punctuation, and sentence-level issues with in-document suggestions [3]. It is a proofreading aid, not a writing tutor or a substitute for reading your draft aloud.

Not through student-facing tools like Draft Coach — AI writing detection appears in the instructor's report [4]. That is why many students preview their AI and similarity scores with a dedicated service before submitting.
