Plagiarism Checking, in Numbers
Charges and delivery are those of the similarity-check service; limits are from UGC Regulations 2018 and the journal’s own policy.
How to Check Your Paper, Thesis, Book or Assignment
The check is the same; what you look for, and the limit you must meet, depend on the document.
Research paper
- How to check
- Check the full manuscript before submission, references included; the report lets you exclude them. Fix matches in the introduction and literature review first.
- Typical limit
- Journals commonly ask for under 15–20%; JMVRA looks for under 15%.
Thesis or dissertation
- How to check
- Check each chapter as you finish it, then the complete thesis before submission to the university.
- Typical limit
- UGC Level 0 is up to 10% similarity, excluding permitted material.
Book manuscript
- How to check
- Check the whole book, including quoted passages, before it goes to layout. Contributed chapters in an edited book should each be checked.
- Typical limit
- Publishers set their own limit; a clean report before production avoids rework.
Assignment or project
- How to check
- Check the final draft, quote and cite every source, and keep the report if your institution asks for proof.
- Typical limit
- Set by your college or course; ask before you submit.
Check Plagiarism with iThenticate in Six Steps
No account and no subscription — you pay for the one report you need, at jwbook.org/similarity-check (opens in a new tab).
- Prepare the file. Word (.docx) or a text-based PDF. A scanned page has no text to compare. Keep references in; exclude them in the report.
- Choose the page band. Bands are counted at about 250 words a page, so formatting changes do not move a document between bands.
- Submit the request. Open jwbook.org/similarity-check, attach the file and choose the band. You receive an acknowledgement with a reference number.
- iThenticate runs the check. The document is compared with web pages, published journal content and submitted work; AI-writing detection runs too if you asked for it.
- Read the source breakdown. Look at which passages match and where they come from — the breakdown matters more than the single percentage.
- Revise and recheck. Rewrite in your own words and cite properly, then recheck before you submit to the journal, university or publisher.
Best Plagiarism Checker Tools, Compared
The tools researchers and institutions use most. For journals, theses and books, what matters is coverage of subscription journal content — free web checkers do not have it.
| Tool | Made by / for | Strength | How to access | AI writing |
|---|---|---|---|---|
| iThenticate | Turnitin · researchers, journals, publishers | Largest scholarly database; powers Crossref Similarity Check | Publisher / per report (this page) | Yes |

Cheap “Turnitin reports” sold through shared student accounts can store your document in the student repository, so the published version later matches itself. An iThenticate check does not.
UGC Plagiarism Levels for Theses and Dissertations
The UGC (Promotion of Academic Integrity and Prevention of Plagiarism in Higher Educational Institutions) Regulations, 2018 grade similarity in four levels. Universities check theses with the software their institution provides, such as DrillBit under ShodhShuddhi.
Properly cited quotations, references, common knowledge and standard terms are not counted as plagiarism. Check your own university’s rules too.
Plagiarism Check Charges by Page Band
One report per document, priced by length at about 250 words a page. AI-writing detection is available on request. Standard delivery is 1–2 working days; the largest bands take longer.
