What Is a Turnitin Pre Submission Check?
A Turnitin pre submission check (also called a precheck, preview, or draft check) runs your near-final file through Turnitin before the graded submission counts. When set up correctly, you receive the same two report families most Turnitin-enabled courses use:
Similarity report. The headline percentage shows how much of your text matches Turnitin’s database and your instructor’s comparison settings. Turnitin treats this number as a starting point for review, not an automatic plagiarism verdict—properly quoted material, common phrases, and bibliography entries can all contribute depending on assignment filters (Turnitin Guides: Accessing the Similarity Report).
AI writing report. This is separate from similarity. Turnitin states that the AI percentage is independent of the similarity score and that AI highlights do not appear inside the Similarity Report (Turnitin Guides: Using the AI Writing Report). Instructors are expected to apply human judgment and institutional policy; AI detection should not be the sole basis for misconduct findings.
What a preview is not: It does not replace your instructor’s rubric, prove misconduct either way, or guarantee an identical score when you upload to the graded assignment. Database updates, file-format differences, and instructor exclusion settings can shift results between runs. The value is decision time—fix honest mistakes while edits are still cheap.
Students search this topic under many names—turnitin precheck, check turnitin before submitting, turnitin submission test—but the core idea is identical: see Turnitin feedback on your draft while you can still change the file.
Institutional vs Third-Party Paths: Which Preview Fits Your Course?
Turnitin does not give every student a standalone “check my paper” button on the open web. The help center is explicit: students cannot self-check inside Turnitin without submitting to an instructor-created assignment—unless the school enables Turnitin Draft Coach or provides a practice slot (Turnitin Help Center). That leaves two broad families of legitimate pre submission checks:
| Path | How it works | Best when |
|---|---|---|
| Institutional (LMS or Draft Coach) | Your school’s Turnitin license, course assignment, or Google Docs add-on | You have a draft slot, resubmissions, or campus Draft Coach access |
| Third-party official preview | Independent service returns official Turnitin similarity and AI writing reports on a private copy | No LMS practice slot exists and your handbook allows outside uploads |
Institutional path: LMS draft or practice assignment
Most students who preview for free do it through a course-linked Turnitin assignment labeled “draft,” “practice,” or “optional check.” Upload your near-final file there first. On Canvas, Moodle, or Blackboard, open the assignment → submit → wait for the Similarity Report icon (often 5–15 minutes, sometimes longer at peak times). If resubmissions are enabled, replace the file after edits.
This path uses your instructor’s configured filters—what you see is closest to what they will read on the graded upload. The main constraints are timing (single-attempt courses), visibility (some schools hide AI reports from students), and syllabus rules on how many uploads you get.
Third-party path: independent preview with official reports
When your course has no draft slot and Draft Coach is unavailable, some students use an independent preview that returns official Turnitin similarity and AI writing reports on a private copy of the draft. This is a rehearsal on the same report types instructors typically read—not a substitute for the LMS pipeline.
Critical boundaries:
- Confirm your syllabus or handbook allows outside uploads before using any third-party service.
- Skip sellers promising to “clear” scores, remove AI flags automatically, or bypass institutional review.
- Consumer plagiarism sites that are not Turnitin’s reporting stack often disagree with your course tool; identify which detector your course uses and interpret that report—not a pile of unrelated dashboards.
Reddit pattern (community experience): Threads about pre submission checks often split into students who got a practice assignment from a helpful TA and students who panicked the night before because their course had no resubmission slot. The practical lesson is identical: find out which path your syllabus allows during week one, not on deadline night.
If you want to see how similarity and AI patterns show up on your draft—not a classmate’s screenshot—preview your Turnitin reports while you still have a full revision window.

Turnitin Draft Coach: Early Feedback Inside Google Docs
Turnitin Draft Coach is Turnitin’s student-facing add-on for Google Docs and Microsoft Word Online. It is license-dependent: your institution’s Turnitin administrator must enable it; it is not a public download any student can install without school setup (Turnitin Draft Coach FAQ).
When enabled, Draft Coach provides formative feedback on:
- Similarity checking — up to three Similarity Checks per draft document, with guidance on interpreting matches
- Citation checking — unlimited runs for missing references or citations (MLA/APA support)
- Grammar Guide — unlimited grammar, mechanics, and usage feedback
Turnitin documents that running a Similarity Check in Draft Coach does not add your draft to the student paper repository and will not cause your final LMS submission to match itself (Google Docs Draft Coach guide). That makes Draft Coach one of the safest free pre-check tools—if your campus paid for it.
What Draft Coach does not replace: It focuses on similarity, citations, and grammar. It is not a standalone student portal for the full AI writing report your instructor may see on LMS submissions. AI writing detection is a separate licensed feature; do not assume a clean Draft Coach similarity pass tells you everything about AI flags on the final upload.
Strategic use of three similarity checks: Because you only get three Similarity Checks per document, batch revisions between runs—early outline for missing quotes, near-complete draft after citation fixes, final polish before copying into the LMS file.
How to Read Your Similarity Report During a Pre Submission Check
Numbers only help if they change your next hour of work. During a pre submission check, treat the similarity report as a match map, not a pass/fail grade.
Start with the headline percentage—then open the breakdown
The overall similarity score is a summary. Your real work is in the source list:
- Is this a missing citation or a missing quotation mark on a block quote?
- Is the match from your own prior submission stored in Turnitin’s repository?
- Is the overlap from the reference list or common phrases your instructor may already exclude?
A double-digit similarity score is not automatically “bad.” Literature reviews, methodology sections, and heavily cited introductions often cluster matches. Your job in preview is to explain or fix each flagged passage before the graded upload.
Common similarity surprises beginners misread
| What you see | Often means | What to do |
|---|---|---|
| High overlap on the reference list | Bibliography counted before exclusions | Confirm instructor filters; fix if references are duplicated in body text |
| Match to your old essay | Prior course submission in repository | Cite yourself or confirm reuse policy with instructor |
| Match to a group template | Shared outline left in file | Remove template language; rewrite in your voice |
| “Small” percentage with no obvious source | Short uncited paraphrase | Open each match link; fix the worst uncited string first |
File-format pitfall: Previewing a .docx but submitting a .pdf with different pagination can change match boundaries. Use the same export type you plan to upload.
How to Read Your AI Writing Report: *% and 0% Explained
The AI writing report is separate from similarity. Turnitin’s AI indicator scores statistical patterns in qualifying prose—long-form sentences in essays—not poetry, scripts, code blocks, bullet lists, or tables the same way (Turnitin Guides: Using the AI Writing Report).
Display rules beginners should know before screenshotting
When you open the AI writing report, two display behaviors confuse first-time readers:
- Scores below 20% show as *% (an asterisk), not as single-digit percentages like “4%” or “11%”—because the model carries higher false-positive risk in that range.
- 0% is the usual explicit low numeric outcome students see.
Do not treat *% as a free pass or 0% as proof no instructor will ask questions. Read which sentences highlight and compare them to your syllabus AI policy. Instructors may see panels or settings your student LMS view hides.
Read highlights, not only the headline indicator
Walk through flagged passages in order of impact:
- Introduction and conclusion — polished with a writing assistant? Rewrite with your own analysis of why the source matters to your argument.
- Generic summary language — “plays a crucial role,” “in today’s society,” “it is important to note” without specific evidence. Replace with course concepts and named sources.
- Mixed-format essays — prose plus tables or bullet lists may show a gap between the headline percentage and highlighted sentences. Focus on highlighted prose sections.
When AI highlights disagree with your memory: Check short polished sections you machine-smoothed last. Some students report AI flags on paragraphs they edited heavily with generative tools even when similarity is already clean—that is a signal to rewrite in your own voice, not to chase a different consumer checker.
Worked scenario (composite student experience): Sam, a first-year psychology student, ran a course draft slot 48 hours before the final deadline. Similarity sat at 14%—mostly an uncited paraphrase from a textbook until Sam added a page number. AI highlights covered the opening paragraph Sam had smoothed with a writing assistant. After rewriting that section with course-specific examples and re-exporting the same .docx, similarity dropped to 9% and AI highlights moved off the thesis sentence. The preview did not “pass” the paper; it bought time to fix honest mistakes.
Limitations Every Pre Submission Check Has
Understanding limits prevents false panic and false confidence.
Scores can shift between preview and graded upload. File changes, export format, database updates, and instructor exclusion settings all affect results. A clean preview reduces surprises; it does not guarantee identical numbers on the official attempt.
Different detectors disagree. GPTZero, Originality, Grammarly, and other tools often show different AI or overlap signals on the same file. Identify which detector your course uses and interpret that report in context of syllabus policy—not a pile of unrelated dashboards.
Preview does not replace disclosure rules. If your syllabus requires AI use statements, add them using the exact wording your instructor expects—regardless of what the report shows.
Not all content types score reliably. Turnitin’s AI report needs at least 300 words of qualifying prose in long-form writing and caps at 30,000 words. Essays mixing prose with code, poetry, or structured lists may produce partial or confusing highlights.
Institutional visibility varies. Some courses show similarity to students while AI writing stays faculty-only until release. Email your instructor when policy is unclear.
Pre-Submission Checklist Before Your Final Upload
Use this checklist on the file you plan to submit for a grade:
- Confirm the correct assignment slot—draft vs final, correct course, correct attempt number.
- Read the syllabus for rules on outside uploads, AI disclosure, and resubmission limits.
- Export the exact file you will submit (
.docxor.pdf); name the version clearly (Essay_v3_48h.docx). - Run both reports when available—similarity first if uncited quotes drive the problem; AI first if similarity is clean but highlights cover machine-smoothed prose.
- Fix similarity issues—missing quotation marks, page numbers, and reference entries before full paragraph rewrites when matches drive the report.
- Rewrite flagged AI prose with your own analysis; add required AI disclosures using syllabus wording exactly.
- Re-export and re-check if you made major edits and your syllabus allows another run.
- Keep dated drafts in case your instructor asks how you revised.
- Do not post report screenshots publicly if your program treats them as confidential.
- Email before the graded upload if you see high similarity you cannot explain, AI highlights on sections you believed were fully human-written, or your student view hides AI scores but the syllabus references AI review.
Short email template:
Subject: [Course] [Assignment] – question before final upload
Hi Professor [Name], I previewed my draft and saw [similarity/AI highlights] in [section]. I plan to [cite/rewrite/disclose]. Is that approach acceptable before I submit tonight? Thank you, [Name]
Before you upload
Step 4 is where deadline week is won or lost: preview both similarity and AI on the exact file you plan to upload. If you have not done that yet, run your draft once while you can still edit citations and body paragraphs.

FAQ
Can you check Turnitin before submitting without an instructor assignment?
Not inside Turnitin itself unless your school gives you Draft Coach or a practice assignment (Turnitin Help Center). Many students without LMS draft slots use an independent preview that returns official Turnitin similarity and AI writing reports on a private copy—confirm your institution allows outside uploads first.
Is there a free Turnitin pre submission check?
Free-at-point-of-use checking usually means your LMS assignment with resubmissions, a practice folder, or Turnitin Draft Coach if your institution enabled it. Turnitin does not sell a personal student account on the open web. Websites promising unlimited free Turnitin scans without a class ID are often scams—they may store your essay or show fake reports.
What is the difference between a Turnitin pre submission check and the final upload?
A pre submission check runs on a draft or practice slot before the graded attempt counts. The final upload is what your instructor grades. Scores can differ between runs because of file edits, format changes, or database updates—but previewing on the same file type reduces surprises.
How long does a Turnitin pre submission check take?
Similarity processing often finishes in 5–15 minutes inside the LMS but can queue during peak deadline windows. Allow extra time the night before a major deadline in case of processing delays.
What does *% mean on the Turnitin AI report?
When Turnitin’s AI indicator shows *%, the model detected a range below 20% where false positives are more common; 0% is the usual explicit low number. Read highlighted sentences and follow your course AI policy—do not treat *% as automatic clearance.
What is a good similarity percentage on a pre submission check?
Turnitin does not publish a universal “passing” similarity score. Context matters: heavily cited papers, literature reviews, and methodology sections often show higher overlap. Focus on fixing uncited matches and following your instructor’s guidance—not chasing a magic number.
Should I fix similarity or AI first during preview?
Similarity first when uncited quotes, missing references, or pasted summaries drive the report. AI first when similarity is already clean but highlights cover sections you know you polished with a generative tool. Re-check both metrics after major edits.
Is a Turnitin pre submission check cheating?
Previewing your own draft to find missing citations or awkward machine-smoothed prose is generally consistent with academic integrity if your syllabus allows the check and you do not misrepresent authorship. When unsure, ask your instructor or writing center.
Can I run a Turnitin pre submission check online if my course has no draft slot?
Services such as Turnitin0 let you upload .docx, .pdf, or .txt and receive official Turnitin similarity and AI writing reports for pre-submission review; papers are not archived or sent to third-party databases. Confirm your syllabus allows outside checks before uploading.
Will my preview score match my LMS submission exactly?
Not always. File changes, export format, database updates, and instructor exclusion settings can shift results. Previews reduce surprises; they do not guarantee identical numbers on the official attempt.
