Students across Sri Lanka need real Turnitin Similarity and AI reports before final submission — but many free or student-mode tools permanently index your draft. That creates self-plagiarism when you re-upload a revised version to your university portal.
What “No-Repository” means
Turnitin can run a submission in a mode where the paper is analysed but not stored in the institutional or global repository. Instructor accounts can enable this setting. Your text is compared against the database; it is not added as a new source for future matches.
Why standard student checks are risky
- University LMS or student-mode uploads often store papers permanently.
- Your own draft becomes a matching source on the next scan.
- Revisions can show 80–100% similarity against yourself.
- You lose control over who can see your unpublished research.
Safe workflow for Sri Lankan students
- Finish a draft (thesis chapter, assignment, or research paper).
- Run a private No-Repository Turnitin check (Similarity + AI).
- Fix citations, paraphrasing, and AI-flagged sections.
- Re-check if needed — still without indexing.
- Only then submit through your official university portal.
What you receive
You get official PDF exports: a Similarity Report (highlights + sources) and an AI Writing detection report from Turnitin Feedback Studio — the same family of reports lecturers review.
