Honest by design
Auto-deleted
Your upload and its extracted text are purged the moment your report is ready. We keep only the order record — never your words.
Never added to a repository
Checking your draft here will not make it "match itself" later. Your document is not stored in any database of documents.
No false claims
We are a similarity checker using a licensed third-party engine. We are not Turnitin, and no checker can guarantee the score your university's own system will produce — anyone who promises that is not being straight with you.
Frequently asked questions
Is this Turnitin?
No. MyThesisCheck is an independent service that uses a licensed third-party similarity engine to compare your document against web pages and publications. Turnitin is a separate company that sells only to institutions. Our score is a strong guide to what an institutional check will find, but the exact percentage can differ because databases differ.
Will checking my document here make it flag later?
No. Your document is never added to any repository or database, and it is deleted as soon as your report is generated. A later check by your university compares against published sources and other students' work — not against anything you did here.
What similarity percentage is acceptable?
There is no universal number — every institution and assignment sets its own expectations, and a score built from properly cited quotations can be fine while a lower score with one large uncited match is not. Our guide explains how to read your score: What is a similarity score?
How long does a check take?
Most reports are ready within a few minutes of payment. Large dissertations can take a little longer. Your report page updates itself — keep the link.
What file types and sizes do you accept?
.docx, .pdf and .txt, up to 100,000 words per document. Scanned-image PDFs contain no readable text; if we can't extract text from a file we tell you before any payment.
What do you keep after my check?
Only order metadata: your email, the file name, word count, price, score and timestamps — so we can support your order and keep our accounts. The document and its text are deleted.
