The best plagiarism removers are lifesavers.

This is especially so when many students would like to use ChatGPT to help them with their homework.

Nearly nine in 10 (89%) of survey respondents reported that they had used the platform to help with a homework assignment, according to research from  

The survey also found that:

  • 48% of students admitted to using ChatGPT for an at-home test or quiz 
  • 53% had it write an essay 
  • 22% had it write an outline for a paper

Even without using ChatGPT, there are still many iconic cases of plagiarism. 

Take Taylor Swift, for example. The pop sensation was sued by Sean Hall and Nathan Butler, who penned “Playas Gon’ Play” in 2000.

The song, which was released by former girl group 3LW, contains similar lyrics to Swift’s 2014 “Shake It Off”, particularly in its chorus. 

Hall and Butler previously sued Swift in 2018 but were dismissed by the judge. Three years later, the lawsuit was reopened. 

One student was also accused of plagiarism after giving a speech at Duke University’s commencement ceremony.

The Chronicle — Duke University’s student-run news organisation — reported that Priya Parkash’s speech was similar to student Sarah Abushaar’s 2014 Harvard University commencement speech.

Abushaar’s speech went: “I saw it in the big and obvious things: We had our own version of the Statue of Liberty, the John Harvard statue; our own embassies, the Harvard Clubs of Boston and London; a tax collection agency, the Harvard Alumni Association; and an endowment larger than more than half the world’s countries’ GDPs.”

Parkash’s speech went: “We also have our own version of Christ the Redeemer — the statue of James Buchanan Duke standing atop an octagonal pedestal to grace Abele Quad. We also have an IRS with its surprisingly bubbly fleet of tax collectors — the Duke Alumni Association. We also have the equivalent of the Federal Reserve, DUMAC, which manages an endowment larger than the GDP of one-third of the countries in the world.”

It’s clear that plagiarism can occur in many different forms —  and even unintentionally. Before we move on to the best plagiarism removers on the Internet to remove copied content, let’s take a look at how plagiarism occurs: 

What is plagiarism and how can it occur even unintentionally?

Plagiarism is presenting work or ideas from another source as your own, with or without consent of the original author, by incorporating it into your work without full acknowledgement, according to the University of Oxford

This covers all published and unpublished material, including material produced with the use of AI. It even includes re-using your own work without citation. 

At times, you might even plagiarise without realising it. Usually, this happens when you’re unclear about the citation format, paraphrasing rules, or improper use of commonly known facts. 

There are also occasions of unintentional plagiarism due to differing cultural norms.

Types of plagiarism

Verbatim (word-for-word) quotation without clear acknowledgement

When you directly copy and paste the source without citing the author, this is known as verbatim plagiarism. 

If you want to use these quotes, you must make it clear to the reader which parts of your own independent work and where you have drawn on ideas and language from another source.


As the name suggests, it involves paraphrasing another person’s work and presenting it as your own.

A passing reference to the original author in the text may not be enough — it may give the wrong impression that the paraphrased wording or sequence of ideas is entirely your own. 

Patchwork plagiarism

Like a mosaic art piece, patchwork plagiarism involves sourcing quotes and phrases from different articles and putting them together as your own work.

Global plagiarism

This type of plagiarism involves taking an entire piece by someone else and passing it off as your own. It could mean getting someone else to write an essay or assignment on your behalf.

Since this involves intentionally lying about the authorship of a work, this is the most serious type of plagiarism, which can bring about severe consequences.


If you use a previously submitted or published work as new content, that is self-plagiarism, even though you might have received recognition for the previous work.

In the most serious case of self-plagiarism, you would submit a paper that has already been presented for evaluation in a different course.

This isn’t allowed unless the uni has granted you permission to do so.

Revisiting old concepts and passages, however, is not considered plagiarism, so long as proper authorisation is obtained and the correct citation is provided to acknowledge the source.

5 best plagiarism removers to remove copied content

Most of these plagiarism removers are only able to remove text-based plagiarism. 

In the case of AI, a plagiarism remover might not definitively determine whether a language model was used to generate a piece of text.

Still, it can help you identify instances of copying or paraphrasing from other sources.

At the time of writing, it can be hard to detect plagiarism by an AI chatbot.

That’s because AI writing tools use natural language and grammar to craft “unique and almost individualised content,” even if the content is drawn from a database, according to Aaron Leong from Digital Trends.
