Direct answer
Turnitin does not sell a standalone grammar checker app that you download, but it does bundle real-time grammar checking into Draft Coach, an add-in for Google Docs and Microsoft Word that also covers citations and similarity [1]. That means most students access Turnitin's grammar feedback from inside their word processor rather than through a separate program [1]. Draft Coach is made available through your school's Turnitin license, so grammar checking, similarity screening, and citation help live in the same workflow you already use to write [1].
Does Turnitin Have a Grammar Checker App or Built-In Grammar Checking Feature?
Turnitin's grammar checking is built into Feedback Studio, the grading environment instructors use, where e-rater-powered grammar feedback appears in a dedicated Grammar tab next to similarity and rubric marks [2]. It is not a consumer app: students reach it through an institutional Turnitin subscription, and instructors decide whether grammar feedback is enabled on a given assignment [2]. If your professor uses Feedback Studio, the grammar comments you see there are generated by the same engine that powers Turnitin's grammar checking elsewhere [2].
For students, the grammar feature typically shows up in one of two places: as e-rater comments inside Feedback Studio after submission, or as live feedback inside Draft Coach while you are still drafting [2]. In both cases the feedback flags issues like punctuation, spelling, and sentence structure rather than rewriting your text for you [2]. The key point is that Turnitin's grammar checking is a feature of its academic tools, not a separate downloadable app [2].
Access depends on what your institution has licensed and enabled [2]. A classmate at a different university may see grammar feedback on the same assignment while you do not, because Turnitin features are configured per school [2]. If you cannot see a Grammar tab or Draft Coach in your account, check with your instructor or library about what is turned on [2].
How Does Turnitin's Grammar Checker Compare With Grammarly?
Grammarly is a general-purpose writing assistant that works across browsers, apps, and documents, while Turnitin's grammar checking is tied to academic submission workflows [3]. Turnitin explains that the two tools serve different jobs: Grammarly polishes everyday writing, whereas Turnitin's e-rater feedback lives inside the grading and originality tools your university already uses [3].
Grammarly offers continuous, real-time suggestions as you type, while Turnitin's grammar feedback appears when you run Draft Coach on a draft or when an instructor grades your submission [3]. That makes Grammarly more convenient for daily writing but less aligned with the specific feedback your professor sees in Turnitin [3].
The bigger difference is scope: Turnitin combines grammar feedback with similarity checking and AI writing indicators in one academic report, which Grammarly does not provide [3]. If your goal is to match the exact checks your university runs, Turnitin's own grammar and originality features are the more relevant reference point [3].
How Can Students Preview Their Turnitin Grammar, Similarity, and AI Writing Reports Before Submitting?
Turnitin Originality is the product Turnitin designed to give students visibility into their own similarity and AI writing reports before the due date, so problems surface while there is still time to fix them [4]. It is a shift from the old model where students only saw feedback after submission [4].
When your institution enables Originality, you can open a similarity and AI writing view on your own draft before you submit, and combine that with Draft Coach's grammar and citation feedback [4]. This lets you fix flagged passages, citations, and grammar in one drafting loop instead of discovering issues in a graded report [4].
The practical takeaway is that a full Turnitin picture — grammar, similarity, and AI — is available to students before submission when the right tools are enabled [4]. If your school has not turned these on, you can still check your draft against Turnitin's own detection using a private Turnitin check before you submit [4].
If you want to know exactly how your final draft will look in Turnitin's own reporting — grammar aside, the similarity score and the AI writing indicator are what professors act on — turnitin0 lets you run a real Turnitin check on your paper before you ever click submit. You upload your.docx,.pdf, or.txt file and get the same similarity and AI writing reports instructors see, delivered in minutes, so there are no surprises on results day.
