Check for Plagiarism

Why use Quetext over other
plagiarism detection tools?

Trust, but verify

Teachers want to give their students the benefit of the doubt, but that doesn’t mean they shouldn’t still verify their work. After all, plagiarism carries serious consequences (especially the older you get), making this process a valuable learning opportunity.

Our free plagiarism checker for professors and teachers uses ColorGrade™ feedback and DeepSearch™ Technology to show instances of exact vs. fuzzy matches, providing insight into whether you're dealing with unoriginal work, intentional or otherwise.

Helping your students avoid plagiarism


Identify what counts as plagiarism

Students don't always come into your classroom with a complete understanding of what counts as plagiarism.

This is especially true if they've gotten away with paraphrasing for their entire academic career, believing that they don't need a citation if they're putting it "in their own words."

Give your students clear examples of plagiarism in all of its forms, especially those that seem less obvious. Stress the point that it's always better to cite the source when in doubt of whether or not attribution is required.

When in doubt, cite the source

Citations can be a challenging topic for students. In addition to all the rules they have to follow in citing information accurately, they might struggle to decide if or when attribution is necessary.

One of the most common mistakes detected by plagiarism software is paraphrased information that doesn't reference the source. Students may believe that paraphrasing counts as "putting it in their own words" and don't think that this type of writing requires a citation.

With the Quetext citation generator, students can follow the "When in doubt, cite the source" rule without the added pressure of manually formatting each citation.

Always use a plagiarism checker

Even accidental plagiarism can come with severe consequences. When students use the same plagiarism detector their teachers are using, they can avoid potentially questionable material before it becomes a bigger problem.

So, how do teachers detect plagiarism and encourage their students to create original work?

Quetext generates real-time results, using a powerful algorithm designed to identify duplicate content (accidental or otherwise) quickly. Using the same exact tool, students are empowered to be stronger writers, and teachers have the most effective tools to verify their work.

Plagiarism Checker for Teachers FAQ

What do teachers use to check for plagiarism?

Oftentimes, teachers’ instincts alone will alert them right away to suspicious vocabulary, turns of phrase, or complex concepts that seem out of step with a student's typical work.

But more often than not, they turn to online tools like Quetext to verify their suspicions, as well as pick up on all instances of duplicate work that they might not catch on their own. Plus, relying on an automatic plagiarism checker that’s designed to identify these cases in a matter of seconds is going to be much faster and more effective than manual verification and intuition.

How do teachers check for plagiarism?

Teachers can't assess the actual quality of a student's work if a paper consists of a lot of copied content. Luckily, the process for identifying what content is original versus plagiarized can be automated and save teachers a lot of time.

All they have to do is enter their students' text into the Quetext plagiarism checker, which immediately begins evaluating for copied content. It then returns a plagiarism score, along with a ColorGrade™ report of exact matches (red), fuzzy matches (orange), and original content (green).

Educators can see at a glance exactly where there are instances of unoriginal work, the level of plagiarism involved, and where citations are required but missing.

How do you tell if a student plagiarized?

It can be challenging learning how to tell if a student plagiarized, especially if you’re trying to do it without an online plagiarism checker. How do teachers catch plagiarism when paraphrasing and rewriting some of the words makes it harder to find exact matches?

Students may not even be aware that their "patchwork" or "mosaic" plagiarism violates academic standards for copied content.

There are a few red flags that teachers look out for:

  • Word usage and language that doesn't align with a student's typical writing
  • Concepts that go far beyond the scope of the class or seem overly sophisticated
  • Incorrect or inconsistent citations, especially from research sites not typically endorsed by educational institutions
  • Content that appears too similar to another student's paper or written previously by the same author

Even with those signs of plagiarism in mind, it's easy to miss paraphrased text that should be cited but isn't. With Quetext, educators can skip the manual scan and rely on the best plagiarism checker for teachers to automatically provide the most accurate evaluation.

What types of plagiarism are teachers looking for?

Students often believe that the only way to plagiarize is to copy another person's work word-for-word. In reality, teachers are also on the lookout for:

  • Self-plagiarism, where an author's previous work is quoted without proper citation.
  • Patchwork and mosaic plagiarism, which involve pulling together bits and pieces of paraphrased content into something that might seem "new" but is plagiarized.
  • Accidental plagiarism, which is a form of plagiarism that often goes unnoticed by students who are not well-versed in proper academic citation standards. This could be anything from forgetting to include an in-text citation to listing the incorrect author as the source of a quote. While these seem like minor offenses, universities often adopt a "no tolerance" policy for unintentional copyright infringement.

Is there a free plagiarism checker for teachers?

Teachers want to focus on their students’ work from an academic perspective, without worrying whether or not they have copied content. That said, they need a way to check for plagiarism without having to scour search engine results for matching phrases or rely on their own intuition and memory.

Quetext is a free online plagiarism checker for teachers that scans billions of search engines, web pages, and papers from all over to help teachers identify cases of plagiarism and copyright infringement in their students' written work.

Once Quetext has completed the check, teachers receive a plagiarism report generated by our sophisticated algorithm and proprietary DeepSearch™ Technology.

Which free plagiarism checker is best?

There are several plagiarism tools available for teachers, students, bloggers, and copywriters. However, Quetext offers the most advanced algorithm on the market at the best rate. Not to mention, it’s far more accessible than its most common competitors, Turnitin and Grammarly.

Quetext helps both sides of the academic relationship (teacher and student) by quickly detecting any and all instances of exact vs. fuzzy matches, color-coding them, and then providing the built-in tool to generate and add citations where necessary. The free plagiarism checker is a must-have tool for anyone that needs to verify their work, but most teachers eventually upgrade to the Pro version to cover all their plagiarism evaluation needs.

How can I help students avoid plagiarism?

Helping your students avoid plagiarism starts with explicit instruction on what it is. Students should understand that both accidental and intentional plagiarism carry the same consequences, regardless of their intentions.

It helps to emphasize how crucial academic integrity is for their growth as a learner and their future as a professional. Discuss real-life examples of plagiarism impacting a student's reputation within the academic community or even instances of plagiarism that affected best-selling authors.

Teachers can also welcome students to join in on informal writer's workshops with their peers to work through the writing process in a safe space. This can eliminate a common plagiarism trigger—the belief that a student can't do well, so they must resort to cheating to pass the assignment.

Finally, it’s possible that students aren’t sure where to find the right tools and are asking “What do teachers use to detect plagiarism?” Encourage your students to use the same platform you use as a teacher to verify their work. This helps build trust, as students are equipped with the same tools to check their writing before handing it over to the teacher who will then do the same.

Quetext DeepSearch™ Technology sets the standard of excellence for plagiarism detection tools. Show your students how simple it is to paste their text into the plagiarism checker, and we'll get to work comparing billions of sources for plagiarized content.

In no time at all, they’ll have a report containing contextual analysis, fuzzy matching, and conditional scoring they can use to optimize their writing for pure originality and correct source citation. When it comes time to submit their work, they can breathe easier knowing they've done their due diligence.
