Yes, you can check an assignment for plagiarism before you submit it. Upload the PDF or Word file or paste the text: the first 1,500 words are checked free, with no sign-up and no name, and the whole assignment is €7 once. Your sentences are compared word for word with Wikipedia, open-access academic papers and the open web, including a live web search, and you get a similarity percentage with every matching passage and its source. Your reference list is looked up in public catalogues too. It does not compare with paywalled journals or other students' work, and it does not detect paraphrase, so your university's own report is still the one that counts.

Why Check an Assignment for Plagiarism?
Lost references
The most common problem is not copying on purpose: it is a quotation whose reference disappeared during editing. Matching passages show you where.
Sources everyone uses
When a whole class cites the same article, the same passages match for everyone. Quoted and cited, they are fine; uncited, they are the first thing a marker sees.
Group work
In a merged group assignment nobody knows which paragraph came from an open browser tab. Check the final document, not each part.
Before, not after
The course report arrives after submission, when nothing can be fixed. A check beforehand is for the passages you can still correct.
How the Plagiarism Check Works
- Upload a PDF or Word file, or paste the text. At least 300 words are needed.
- Your sentences are compared, word for word, with Wikipedia, open-access academic papers and the open web, including a live web search for selected sentences.
- You get a similarity percentage and every matching passage with the source it matches.
- Every entry in your reference list is looked up in public catalogues, so you can see which ones were found.
- Standard academic phrasing that recurs across many papers is shown separately: common academic language, not copying.
Clean Citations Under Time Pressure
- Paste every source together with its reference, in the same step.
- Highlight anything you pasted 'to rewrite later' and search for the highlight before submitting.
- Quote and cite a shared course text rather than rewording it to avoid a match.
- Cite lecture slides and course readers like any other source.
- Check the final version you will upload, not a draft.
Frequently Asked Questions
The first 1,500 words are free, with no sign-up and no card. The whole assignment is €7 once, with 14 days of re-checks, and the same payment unlocks the AI check.
Wikipedia, open-access academic papers and the open web, including a live web search. It does not compare with paywalled journals, other students' submissions or essay sites, and it does not detect paraphrase. A university checker such as Turnitin compares with collections we cannot access, so its report is the one that counts; this check comes before it.
Not by itself. A quotation in quotation marks with its reference is a match and is fine. What matters is whether borrowed wording is quoted and cited. The result shows every matching passage so you can check exactly that.
The check runs on our servers. For the web search, isolated sentences, never the whole document, the file or anything that identifies you, are sent as search queries to a web search provider, as our Privacy Policy (§ 2.1.4) explains. We never ask for your name or university.
No. The fixes it points to are the ones a writing centre would give: quote and cite what you borrowed, and write the rest in your own words. Rewording a borrowed passage to hide it is still plagiarism.
