"No Repository" in Turnitin, Explained
"No repository" or "do not store" is a submission setting in Turnitin — and it changes what happens to your draft after it's checked. If your instructor mentioned it, or you're deciding whether to submit a draft, here's what it means in practice.
The standard repository vs no-repository
| Standard submission | No repository | |
|---|---|---|
| Your text is checked | Yes | Yes |
| Your text is stored in the database | Yes — future papers match against it | No |
| Your own resubmission self-matches | Often yes (high similarity vs your draft) | No self-match later |
| Typical use | Final submissions | Drafts, practice checks, thesis chapters |
The classic trap it prevents: you submit a draft for feedback, then submit the final version — and the final report shows 90%+ similarity against your own draft sitting in the repository. No-repository mode keeps that from happening.
What no-repository does NOT change
- Your text is still compared against everything already stored (the internet, publications, the repository as it exists).
- The AI writing score is computed the same way — it's a separate analysis from similarity storage.
- The instructor still sees the report for that submission.
For drafts you'd rather not store anywhere
The most private pre-check is an independent tool with no account and no storage at all. Ours keeps nothing — no repository, no profile, no email — and still gives you the useful part: a score plus the exact flagged lines. Pair it with safe pre-checking habits and the post-submission timeline.
