How to check your Turnitin score before submitting safely

Students say "Turnitin score" for two different numbers: the similarity percentage and the AI-writing percentage. They are separate. Similarity checks text overlap with sources. AI detection estimates how much writing looks machine-generated.

If you only check one number, you can still be surprised by the other. A ChatGPT-written paragraph may have low similarity but high AI risk. A human essay with many quoted sources may have high similarity but low AI risk.

Option 1: use your school’s draft assignment

Some instructors create draft assignments that let students submit early, read the Similarity Report, revise, and submit again. If your course has this option, it is the cleanest free route.

The catch is visibility and storage. Your instructor controls whether you can see the report, when resubmissions are allowed, and whether the draft is stored. Read the assignment settings before assuming it is a private self-check.

Option 2: use Turnitin Draft Coach if your school has it

Some institutions license Turnitin Draft Coach or a similar student-facing writing workflow. It can help with similarity and citation checks before a final submission. Many schools do not provide it, and it may not include the same AI report your instructor sees.

If you have Draft Coach, use it. If you do not see it in Google Docs, Microsoft Word, your LMS, or your school writing tools, your institution probably has not enabled it for students.

Option 3: run a private no-repository Turnitin check

A no-repository check runs the paper through Turnitin without adding it to the student-paper database. That is the key difference between a safe pre-check and a risky upload that creates a self-match later.

PaperCheck is built around that pre-submission use case: you get the real AI and similarity reports, your file is deleted within 24 hours, and the paper is not stored in a repository. For the storage risk, read whether Turnitin keeps a record of checked works.

Where a free AI checker fits

A free checker can be useful before you pay for the official report. It can flag obvious AI-like writing and help you decide what to revise. But it is still an estimate, and it does not check plagiarism or source matches.

Use the free Turnitin AI checker for an instant first pass. Then use a real Turnitin check when you need the official report.

What to do after you see your score

  • If similarity is high: open the source list, check whether matches are quoted and cited, and rewrite uncited overlap.
  • If AI is high: revise generic passages, add your own analysis, and keep drafts or version history.
  • If both are low: still proofread, check citations, and make sure the final file is the version you intend to submit.

Frequently asked questions

Can I check my Turnitin score before submitting?

Sometimes, but not always. You need an instructor-enabled draft assignment, a school tool such as Draft Coach, or a private no-repository Turnitin check.

Can students see their Turnitin AI score before submitting?

Usually no. Turnitin AI scores are commonly shown to instructors, not students. A private Turnitin check can return the instructor-facing AI report before you submit to school.

Can I check my similarity score before submitting for free?

Only if your school gives students a draft workflow. Free AI checkers do not reproduce the official Turnitin similarity report because they do not have Turnitin’s source database.

Will checking my paper first add it to Turnitin?

A normal Turnitin assignment may store your paper. A no-repository check scans the paper without adding it to the student-paper database, which avoids a later self-match.

What score should I check first: AI or similarity?

Check both when the assignment is important. AI and similarity are separate reports, so a low similarity score does not mean the AI score is low.
