Plagiarism Checker Process


Step 1: Easily upload your thesis.

Upload your Bachelor’s or Master’s thesis or dissertation to BachelorPrint in Word, PDF, OpenOffice or any other common format. It is also possible to upload several documents at the same time. The plagiarism checker automatically detects the word count of your document and selects the right plagiarism package for your thesis. The plagiarism checker will then take care of the rest.

Step 2: Comparison with billions of sources in all common languages.

The text of your academic manuscript will be divided into sections, or so-called phrases. Using special algorithms, these will be checked for identical content in the world’s largest database (World Wide Web). The plagiarism checker can be used no matter what language your thesis is written in.


Step 3: The plagiarism report. Easy to understand. Shows the plagiarism quote and is color-coded using a traffic light color scheme.

You will receive a detailed PDF report allowing you to see at first glance whether a possible plagiarism has been found. Each suspected area of your academic work will be highlighted in a given color and the respective source will be listed at the end. In summary, you will see the overall result as a percentage of matches.

The plagiarism checker scans your whole document, looking for plagiarism. This also includes tables and indexes, as it might happen, that whole tables or indexes are copied. Small similarities might always exist on work cited pages.

A plagiarism check of a bachelor’s or master’s thesis (60-80 pages) normally takes between 10 and 20 minutes. It depends on the number of words submitted. In the case of longer pieces of work (200-300 pages), the plagiarism check can take up to an hour.

Yes! The plagiarism check works in all languages. Regardless of the language or if you’re writing a bachelor’s thesis, or a dissertation, the plagiarism checker will work for you. Many of our services here at BachelorPrint are multilingual.

No! For data protection reasons, we don’t save any of our customers’ uploaded documents. We delete them from our server within 24 hours!

The first step of the plagiarism check is to upload your file. This will be temporarily saved on our server. Then the text content of the uploaded document will be extracted and your original file will be deleted. In the next step, the extracted text will be transferred to a temporary database and will be divided into individual sections according to language statistics.

The plagiarism checker then reads the individual sections and searches the World Wide Web for matches. In the last step, a plagiarism report will be generated in which plagiarized areas are be marked in color and the link to the original source is given. If you’re not sure why something has been marked as plagiarism, check out our blog post to find out more about what constitutes plagiarism. But don’t worry! Becasue 24 hours after using the plagiarism checker online, your data will be deleted – completely in line with data protection requirements!

No! It’s very easy! You can just upload your document, choose your payment method and then use the plagiarism checker without a user account or registering. Start your plagiarism check now!

All publicly accessible online sources will be used in the plagiarism check. Databases where payment is required are excluded. If a book is online in a publicly accessible database, then the plagiarism checker will also find this source. Having trouble organising and citing your sources? Check out our blog posts. We have APA citation, Harvard referencing and more.

The BachelorPrint plagiarism checker doesn’t save any uploaded work for data protection reasons, unlike Turnitin. Accordingly, we don’t rely on the same data base as Turnitin.

However, our plagiarism checker searches billions of publicly available sources on the World Wide Web.

Information: If the work is scanned for plagiarism in advance with Turnitin, and the university also uses Turnitin, there is a considerable potential risk for the writer. As Turnitin saves the uploaded work, this will then be in their database. If the university scans the same work on it, it will then be classified as complete plagiarism. We have already heard this a few times. The student’s work was therefore failed in the first instance and they had to prove that they had written the document saved by Turnitin.

It’s possible that the email from the plagiarism checker has gone into your spam folder. In extremely rare cases, our e-mail with the plagiarism report from the plagiarism detector might have been blocked by your e-mail provider and hasn’t been received. Please contact us at [email protected]. We will resend the plagiarism report right away.

For an overview, only text passages that might contain plagiarism are shown in the plagiarism report. The other pages where no plagiarism is suspected will not be shown. So less pages in your plagiarism report is a good sign!

It’s possible that a section of text is marked as suspected plagiarism even though it has already been correctly cited, for example from a book. This happens if the software finds a further online source. In this case, the suspected plagiarism can be ignored and this serves merely as extra peace of mind. To learn more about properly citing your sources, read our blog post about how to cite a book.

It mostly happens unintentionally. By mistake. Unknowingly. Due to time constraints. Even though every single student knows, or should know, that every source from a different author must be identified in an academic paper. Not complying with this principle is committing plagiarism. Therefore, you should use the online plagiarism checker just to be sure.

There are well-known examples that indicate how rigorously academia deals with plagiarism. Writers of bachelor’s theses, master’s thesis and other academic work don’t have to fear being disqualified from their PhD program or even public exposure. However, this is of little consolation to someone who has failed their bachelor’s thesis because of a few ‘forgotten’ citations.

Why are we including so much information on the topic of plagiarism? Because it’s the most essential service that we can offer you to guarantee the success of your academic work. Simply calculate the number of words in your paper and place the appropriate plagiarism check package in your basket. We’ll take care of the rest. All within 24 hours, max, but probably even sooner.
