How to Check Your Thesis in Turnitin Before Submitting

To check your thesis in Turnitin, submit it through your university's thesis or dissertation assignment, ask your library or graduate school for a pre-submission check, or use a Turnitin report checker that does not store your file. Theses are long, so watch the AI report's 30,000-word limit and exclude your reference list. Here is each route and what to look for.

Three ways to check a thesis in Turnitin

Route	Pros	Watch out for
University thesis submission	Official result	May be stored; often only one attempt
Library or supervisor pre-check	Free, often allowed for drafts	Waiting times; AI report may be hidden
Our Turnitin report check	Both reports usually within minutes, not stored	$3.99 per document

Step by step

1. Save as .docx or text-based .pdf, under 100 MB and 800 pages.
2. Check length. AI detection covers up to 30,000 words of prose. For longer theses, check chapters separately.
3. Submit and open the similarity report. Exclude the bibliography and quotes if you can.
4. Review match by match, starting with the largest sources.
5. Open the AI writing report and note any highlighted sections.

Common thesis issues

• Matches to your own published papers or proposal: ask your supervisor to exclude them. See will Turnitin detect my own work.
• Long literature reviews and methods sections often score higher on AI. Rewrite them in your own analytical voice.
• Standard method descriptions match many papers. Cite them and paraphrase properly.
