Avoiding accidental plagiarism

You don't need a plagiarism checker, right?

You would never copy-and-paste someone else’s work, you’re great at paraphrasing, and you always keep a tidy list of your sources handy.

But what about accidental plagiarism ? It’s more common than you think! Maybe you paraphrased a little too closely, or forgot that last citation or set of quotation marks.

Even if you did it by accident, plagiarism is still a serious offense. You may fail your course, or be placed on academic probation. The risks just aren’t worth it.

Scribbr is committed to protecting academic integrity. Our plagiarism checker software, Citation Generator , proofreading services , and free Knowledge Base content are designed to help educate and guide students in avoiding unintentional plagiarism.

We make every effort to prevent our software from being used for fraudulent or manipulative purposes.

The Scribbr Plagiarism Checker is powered by elements of Turnitin’s Similarity Checker , namely the plagiarism detection software and the Internet Archive and Premium Scholarly Publications content databases .

Extensive testing proves that Scribbr’s plagiarism checker is one of the most accurate plagiarism checkers on the market in 2022.

The software detects everything from exact word matches to synonym swapping. It also has access to a full range of source types, including open- and restricted-access journal articles, theses and dissertations, websites, PDFs, and news articles.

At the moment we do not offer a monthly subscription for the Scribbr Plagiarism Checker. This means you won’t be charged on a recurring basis – you only pay for what you use. We believe this provides you with the flexibility to use our service as frequently or infrequently as you need, without being tied to a contract or recurring fee structure.

You can find an overview of the prices per document here:

Please note that we can’t give refunds if you bought the plagiarism check thinking it was a subscription service as communication around this policy is clear throughout the order process.

Your document will be compared to the world’s largest and fastest-growing content database , containing over:

  • 99.3 billion current and historical webpages.
  • 8 million publications from more than 1,700 publishers such as Springer, IEEE, Elsevier, Wiley-Blackwell, and Taylor & Francis.

Note: Scribbr does not have access to Turnitin’s global database with student papers. Only your university can add and compare submissions to this database.

Scribbr’s plagiarism checker offers complete support for 20 languages, including English, Spanish, German, Arabic, and Dutch.

The complete list of supported languages:

If your university uses Turnitin, the result will be very similar to what you see at Scribbr.

The only possible difference is that your university may compare your submission to a private database containing previously submitted student papers. Scribbr does not have access to these private databases (and neither do other plagiarism checkers).

To cater to this, we have the Self-Plagiarism Checker at Scribbr. Just upload any document you used and start the check. You can repeat this as often as you like with all your sources. With your Plagiarism Check order, you get a free pass to use the Self-Plagiarism Checker. Simply upload them to your similarity report and let us do the rest!

Your writing stays private. Your submissions to Scribbr are not published in any public database, so no other plagiarism checker (including those used by universities) will see them.

Google’s new ‘Assignments’ software for teachers helps catch plagiarism

google assignments plagiarism checker

Just in time for the new school year, Google’s educational arm, Google for Education, today announced the launch of new tools aimed at helping teachers fight plagiarism. The company this morning is unveiling Assignments , an updated version of the software previously known as CourseKit, which will ship with new features that help instructors check students’ work to ensure it’s properly cited — not stolen from another source.

Students also can take advantage of the new tools, notes Google, as the feature will allow them to run these “originality reports” up to three times before submitting their final work to their teacher.

This gives students the chance to catch and fix any errors, while also saving the teacher time in grading, the company says.

The updated Google Assignments program does more than help catch cheaters, however.

The software combines aspects of Google Docs, Google Drive and Google Search into a new tool that’s focused on the creation and management of schoolwork, including the collection, grading and feedback process — and now, the ability to check for plagiarism, as well.

Other features include a comment bank to save teachers from typing the same feedback over and over; the ability to assign files to students without having to use the copier; the ability to grade assignments for a class with a student switcher and rubric included, and more.

With the plagiarism checker — the feature called “Originality Reports” — teachers can check for missed citations and other issues. When the work is turned in and locked, the feature will check the student’s text against “hundreds of billions of web pages” and “tens of millions of books,” says Google.

Once the feature is enabled on a given assignment, students can only run the check three times. This allows them the chance to fix oversights, but doesn’t let them abuse the feature to rewrite multiple pieces within a longer report to avoid detection.

Teachers will receive an Originality Report attached to the assignments that details any missed citations and notes the source — like a book or a web page.

“Today’s students face a tricky challenge: In an age when they can explore every idea imaginable on the internet, how do they balance outside inspiration with authenticity in their own work? Students have to learn to navigate the line between other people’s ideas and their own, and how and when to properly cite sources,” explains Brian Hendricks, a product manager for G Suite for Education, in an announcement.

The plagiarism-checking feature is launching into beta testing today , with invites rolling out to schools and teachers over the next few weeks. Assignments is a free addition to G Suite for Education.

The software can be used either as a companion to a school’s Learning Management System (LMS) or a school admin can opt to integrate it with the existing LMS, notes Google.
