- I ordered the Scribbr Plagiarism Checker in combination with Proofreading & Editing. When should I start the Plagiarism Checker?
If you purchased a Plagiarism Checker in combination with our Proofreading & Editing service, you can start the Plagiarism Checker anytime at your convenience.
Scribbr recommends using the Plagiarism Checker after you have received your document and gone through all of the edits. Then you can upload the most recent version of your paper and avoid having to manually transfer changes from one document to another.
- Can I buy an annual subscription for the Scribbr Plagiarism Checker?
At the moment we do not offer an annual subscription for the Scribbr Plagiarism Checker. Plagiarism checks can be bought separately — prices depend on the size of your document.
|Small document (up to 7,500 words)||$18.95|
|Normal document (7,500-50,000 words)||$28.95|
|Large document (50,000+ words)||$39.95|
- How long does the Scribbr Plagiarism Checker take?
The Scribbr Plagiarism Checker takes about 10 minutes to finish. For documents larger than 25.000 words it can take a bit longer. You will be shown an estimate at the order overview. As soon as the check has finished we will also send you an e-mail.
- I uploaded the wrong document to the Scribbr Plagiarism Checker. Can I get a free new check?
If you accidentally uploaded the wrong document to the Plagiarism Checker, Scribbr will not refund you for this check or give you a discount for another check. The check starts automatically upon payment, which is why we cannot change your document anymore.
- Can I use the Scribbr Plagiarism Checker to check the same document multiple times?
Yes. Moreover, the results of a previous Plagiarism Check will not influence the results for a later version of the same document.
Please bear in mind that each Plagiarism Check is charged separately.
- What languages are supported by the Scribbr Plagiarism Checker?
Almost all languages are supported by the Scribbr Plagiarism Checker. You can find a complete list of the supported languages below:
- Will the results be the same as the results of the check used at my school?
The Scribbr Plagiarism Checker is optimized for students, which means that you will receive a detailed report with extra information to fix and prevent plagiarism, similar to the report received by your school.
Schools often have their own database of (prior) theses. Scribbr has no access to those databases. When you copy data from another thesis that is not publicly accessible, the Scribbr Plagiarism Checker will neither be able to detect plagiarism nor identify the source of this data.
However, most theses are actually publicly accessible since many universities and schools have public databases. This means that the Scribbr Plagiarism Checker is able to find these theses.
- Which file formats are supported by the Scribbr Plagiarism Checker?
You can use the following file formats:
The format you use doesn’t influence the final result.
- How can I download my Plagiarism Check results as a PDF?
Downloading your results as a PDF is simple. Just follow these three steps:
Step 1: Open your results page and click on the “print” icon.
Step 2: Click on “print” in the top bar.
Step 3: Choose “Save as PDF.”
- What do I do with a found similarity?
Review every similarity for plagiarism, and decide whether or not you need to revise your text.
- Review the similarity, and think about whether or not the match makes sense to you.
- Revise the snippet if necessary. You can do so by paraphrasing or quoting. Always cite your sources.
- What does my similarity score mean?
Your similarity score shows you what percentage of your text is found within sources in the comparison database.
For example, if your score is 15%, then 15% of the content you wrote is unoriginal, as it matches text in the database.
You will have to review each similarity and decide whether or not you need to revise your work.
What is a good score? How do I update my work?
- Will I get a 100% match at my school when I use the Scribbr Plagiarism Checker?
We understand this concern. However, since the Scribbr Plagiarism Checker does not store any documents that it checks in a shared database, it’s impossible for this to happen.
As an added precaution, you can also personally delete your details and documents from Scribbr’s own server as soon as you’ve received the results of your Plagiarism Check.
- What is an acceptable percentage of plagiarism?
Your work should not contain any plagiarism. This means that even a score of 1% is too high.
However, contrary to popular belief, plagiarism checkers do not detect plagiarism, but similarities. Not all similarities found by the Scribbr Plagiarism Checker constitute plagiarism. Our check sometimes flags the following:
- Properly cited quotes,
- In-text citations or your reference list, and
- Commonly used phrases that are obviously not considered plagiarism.
Because of this, you can generally follow these guidelines:
- A score higher than 10% is troublesome.
- A score between 5% and 10% it is not bad per se.
- A score around 5% is reasonable.
Even if your score is 1%, you will need to review each similarity and decide whether it’s necessary to revise your work.
What should I do with a found similarity?
- What does a similarity score of 0% mean?
A similarity score of 0% means that we haven’t found any similarities in your text.
- Will my document be published on a (public) database?
No, the Scribbr Plagiarism Check does not result in your document being published in any public database (unlike other plagiarism checker services).
As soon as you’ve received the result from the Plagiarism Checker, you can directly delete all details and documents from the Scribbr server.
- Which sources are used for the Scribbr Plagiarism Checker?
The Scribbr Plagiarism Checker compares your document against:
- Over 60 billion of current and historical web sources.
- Over 30 million of articles from scientific information sources and journals from the major scientific publishers.
This content database is provided in partnership with Turnitin.
At the result page of your Plagiarism Check you can see in which database the original source is found.
- What to do with a quote found by the check?
Sometimes a quote is found in your thesis and marked as a similarity by the Scribbr Plagiarism Checker, because the quote is also found in another source.
A quote found by our plagiarism checker is not a form of plagiarism. However, it is important that you have added a reference to this quote. Below we briefly explain the rules to write down quotes in APA Style.
Quotes of less than 40 words
When citing a section of text fewer than 40 words, you use double quotation marks directly before and directly after the quote. Next to that, you mention the author, the year and a page number.
Example: Quote of fewer than 40 words
The definition of soccer is, according to Van Persie (2014), “running back and forth with each other and whoever scores the most, wins” (p. 15).
A famous soccer player always said, “playing soccer with each other on a beautiful Sunday afternoon is the greatest thing there is” (Sneijder, 2013, pp. 2-3).
Quote of 40 words or more
If the quote contains 40 words or more, then place the quote in a separate block, which begins on a new line and is indented in its entirety.
Example: Quote of more than 40 words
The second anniversary of Scribbr was widely reported in the press:
Scribbr is now two years old and that is being celebrated with the introduction of a new version of the APA Generator. Now that more and more students make grateful use of the APA Generator, it is high time for a new version, according to the founders. The APA Generator is very popular because the APA Style has many exceptions. As a result, it is difficult for many students to really get the hang of the APA Style. In addition, the APA Generator saves many students a great deal of time (Schlagers, 2014, p. 3).
