Scoring…

A Verdict is what an independent detector sees. It is not proof of who wrote a text. We cannot predict what Turnitin or any other detector will say.

Long work, checked in sections

Long documents are judged in overlapping slices, and the passages that do not read clearly human are checked sentence by sentence, so you see exactly where the signal comes from. For a whole dissertation, check it chapter by chapter, or use Pro to upload the file.

A Verdict is what an independent detector sees. It is not proof of authorship, and we cannot predict your university's tool.

Questions

My essay is longer than 1,500 words. Can I still check it?

Without an account each Scan takes up to 1,500 words, so check it in parts. A free account takes 3,000 words at a time, and Pro takes 15,000 and reads PDF and Word files.

Do quotations and references affect the result?

Long quotations are someone else's writing and can pull the score either way. Reference lists and tables are left out of what we judge best; paste the body of the essay.

Is my unpublished work safe?

Yes. We never store the text you scan, so there is nothing to leak, publish or train on.
