The BibMe Plus writing and citing tools go far beyond the basics of just proofreading; they also check your paper for plagiarism and help you build your biography quickly.

Detect Unintentional Plagiarism

Finding out that you’ve accidentally infringed on another’s work the night before your assignment is due can leave you scrambling to rewrite sections of your paper, update your citations, and modify your bibliography at the eleventh hour.

If you find that you have accidentally plagiarized, whether on your first, fourth, or final draft, the BibMe Plus plagiarism tool has got you covered. When the BibMe Plus essay checker scans your paper, it searches the web for passages of similar text and highlights areas that may need attention. You have the power to review each flagged passage, as well as the suggested source, to determine if a citation is needed. If you conclude that you did not plagiarize, you can dismiss the plagiarism suggestion and move on to review the next.

After reviewing the suggested sources and identifying the passages which are missing citations, you can choose to start creating a proper citation right then and there. Not only can you create the citation, but you can both add it directly into your paper as an in-text citation as well as to your bibliography at the end of the paper.

All of the BibMe Plus writing and plagiarism check tools and guides are conveniently available 24 hours a day, 7 days a week. So it doesn’t matter if you finish your paper a week early, or a few hours before it is due; help is here whenever you need it.

How Does the Plagiarism Checker Work?

Before subscription-based and free plagiarism checkers became readily available, figuring out how to check for plagiarism efficiently and effectively was a vexing problem. After all, reviewing every sentence by hand and comparing it all with the entirety of the world’s published works for potential plagiarism would be an arduous and potentially impossible task. That’s why instructors across all levels of education often rely on automated scanning tools (like a paid or free online plagiarism checker)  to check for plagiarism and help them identify instances of academic dishonesty; and why students should, too.

A free plagiarism checker may scan your paper for matching text and merely highlight the problem areas and return a percentage that reflects the amount of unoriginal writing it uncovered. The BibMe Plus paper checker offers a lot more than a free plagiarism site and gives you the information you need to make fully informed and intelligent decisions. Our plagiarism detector reveals any passages that require your review and returns the results to you, along with links to the source that contains matching text.

About the Plagiarism Checker and Grammar Check Tools

You’ve done the research, drafted and revised your paper, and took care to credit all of your sources. The last step before you submit your paper is to proofread it in order to catch any missed errors or citations. A missing preposition, misused adverb, or misspelled interjection might escape you, but you’re unlikely to escape your teacher.

The BibMe Plus grammar checker gives you the feedback you need to help polish and improve your paper before you turn it in, not after. Not only does it flag spelling, grammar, and punctuation errors, but it also gives you helpful tips that explain why the item is flagged so you can correct it, learn from it, and become a better writer.

A quick scan of your paper with the BibMe Plus plagiarism tool will also help to reveal any passages that, while perhaps unintentional, would still be considered plagiarizing. With tailored tips and an easy-to-use interface, our writing tool can help you unlock the magic to more natural, relaxed, and efficient editing to help ensure that your writing is clear, consistent, and properly cited.

The best part about it? Instant suggestions. No further reading, waiting for a human proofreader to respond to you, or racing across campus to get to the writing center before it closes.

The BibMe Plus grammar checker is available precisely when and where you need it. Conduct an on-demand spell check and grammar check at any time of day to validate the integrity of your work, and to generate any missing citations, all in a matter of seconds.

What is Plagiarism?

Committing academic dishonesty could lead to failing grades and even expulsion Knowing the potential consequences of plagiarism certainly makes it clear why you should avoid it. However, without a concrete definition, abstaining from it can prove challenging.

If you’re wondering, “What does plagiarism mean?” an easy to remember plagiarism definition is that it’s the act of using someone else’s work or ideas without giving them proper credit. It’s important to note that this definition is not bound by intention, and students may commit it both knowingly and unknowingly in a research paper.

Learning to define plagiarism is just the first step in developing the awareness necessary to avoid it. Identifying it in its various forms is the crucial next step, combined with consistently utilizing a subscription-based or free online plagiarism checker as a non-negotiable element of your paper-writing process.

Is your paper in need of a plagiarism check?  The BibMe Plus grammar check and plagiarism tool has got you covered! It’s designed to help spot those pesky places in your paper that may get red marks from your teacher, and it couldn’t be easier to use. Simply upload or paste your paper into the online plagiarism checker and, in no time at all, you’ll receive your results and can review any areas of concern. Try it now!

Not ready to check for plagiarism yet? Not to worry–the BibMe Plus plagiarism tool is available 24/7, so you can research, write, and revise when it’s best for your schedule.

Examples of Plagiarism

While it’s critical to understand the plagiarism definition as it’s broadly defined, it’s just as vital to learn the various ways it can occur if proactively preventing plagiarism is your goal.

Direct Plagiarism:

Direct plagiarism is the deliberate act of copying another individual’s work or idea into an assignment without providing any type of acknowledgment. An example of this would be a student copying and pasting text from a source into their project, without using quotation marks or any kind of attribution.

Incremental Plagiarism

Copying bits and pieces from a single sentence and adding them into a project without attribution is a form of literary theft called incremental plagiarism. Just as with direct plagiarism, the incremental form attempts to disguise when a student or writer is taking credit for words and ideas that are not their own.

Patchwriting:

When a writer rephrases another author’s words (and it remains similar to the original words) and includes them without attribution in their work, it is known as patchwriting or mosaic writing.

How does it happen? Perhaps the writer rearranged words in the sentence, subbed out a few adjectives with synonyms, or used bits and pieces of the original wording and mixed it with their own. No matter the method, the original wording is often easy to spot as it peeks through its patchwork disguise.

Self-Plagiarism:

Plagiarizing another author’s words or ideas is an issue that most students recognize as wrong, but many are shocked to learn that reusing their own words can also fit the plagiarism definition. After all, they ask, how can I steal from myself?

Self-plagiarism is less about stealing and more about deceiving. When a student refurbishes or reuses work they completed in the past and turns it in a second time instead of completing new, original work, they are not honest with their teacher. Even reusing portions or paragraphs of your previous work without disclosing it is dishonest.

Do you have a paper you want to evaluate so you can confirm you’ve completed your research responsibly without plagiarizing (by accident)? A quick scan with the BibMe Plus plagiarism tool will help highlight phrases, sentences, or paragraphs in your paper that are found elsewhere on the internet. Each highlighted section has a prompt that will also ask you if you need a reference for it. Even better? If you review the source and determine that you need to add a citation, the plagiarism check tool will guide you through the steps of creating and inserting your reference. Pretty awesome, right? We think so too.

Lesser-Known Examples of Plagiarism

There are quite a few acts of intentional or unintentional dishonesty that students are surprised to learn also meet the definition of plagiarism.

Misleading Citations:

Including misleading citations is a form of academic dishonesty that is just as serious as direct infringement.

To understand how this fits into the plagiarize definition, consider the final result. If this type of plagiarism is undetected, the writer has deceived their audience and created a false belief about the words and ideas in the source material and its author. Whether it occurs intentionally or unintentionally, misleading citations draw a false link between an idea and a source and harm a student’s credibility.

Invented Sources:

While misleading references can occur as a result of not understanding your research, invented sources are more often the result of insufficient research or intentional deception. A student who can’t find a source to back up a point they want to make or who doesn’t want to commit the necessary time to ethically complete a paper might resort to including one or more invented sources in their bibliography. Whatever the cause, an invented source creates an illusion of credibility by tying an idea to a source that doesn’t exist.

An invented source can also be the result of poor note-taking. Perhaps you found the perfect quote to include in your introduction but forgot to write down the source. You know it’s wrong to plagiarize, but unless you invent a source you’ll have to remove the quote, right?

Wrong! Rather than choosing between removing the quote or inventing a reference, let the BibMe Plus plagiarism tool free up some time by helping you find the source and create an accurate citation. It’s quick and easy to scan your paper for plagiarism and, most importantly, it’s the ethical thing to do.

What Is Not Plagiarism

With the definition of plagiarism covering so much ground, it’s easy to raise the alarms and wonder if even the most innocent of acts might be construed as plagiarizing. Our advice? Don’t panic. Instead, sit back, relax, and check out these times when you can write your heart out, worry-free:

Common Knowledge:

Information that is widely known and accepted as fact is considered common knowledge. This can either be information that is known to most people in the world, in your country, in your state, or even just in your field of study, depending on the audience for your work. For example:

J.K. Rowling wrote the Harry Potter series.

This is a fact that is known widely enough that it is considered common knowledge and does not require a citation.

If your statement is considered common knowledge, you can include it in your paper without creating a citation. Keep in mind, though, that research papers showcase new ideas and analysis. Common knowledge is acceptable to include, but make sure you mix in information from outside sources as well.

Attributed Quote or Idea:

To include the ideas of others in your papers, you need only to attribute them to the original author to ensure you safely stay on the side of academic integrity. A proper paraphrase or direct quote with a citation is an excellent way to promote a point in your paper, while also demonstrating that you fully understand the author’s idea and have completed your research responsibly.

While most writers remember to add references for direct quotes, they can sometimes forget to include references when adding paraphrases into papers. A free plagiarism site may only help these writers pinpoint passages, but the BibMe Plus tool also helps you develop accurate references, in Chicago citation style and many others, in all types of situations. Quotes, paraphrases, full references: you name it, our plagiarism checker does it, and does it well.

Now that we’ve learned what is and isn’t plagiarism, let’s look at how to avoid it entirely.

How to Avoid Plagiarism

When you first learn to define plagiarism and realize how expansive the definition is, it can be intimidating to think about all the information you have to cite. That’s where the BibMe Plus online plagiarism tool comes in by helping to spot intentional and accidental plagiarism and flagging any matching text for your review.

When you use the plagiarism tool, or any of our resources, your paper always stays in your control. You’ll be given the potential source for each flagged passage so you can review it and decide whether to create a citation or dismiss the alert.

If you find that you need to add a citation, we’ve got your back. There are BibMe citing tools that can help guide you through the process of creating and styling a citation for your paper.

No matter what tools you use to help complete your work ethically, whether they’re free plagiarism tools or not, you are ultimately responsible for the work that you turn in. Remember, the best time to find errors or unintentional infringement is BEFORE you turn in your paper, not after. When in doubt, run a BibMe Plus plagiarism check to help you find any passages that you may have missed on your own, and use the free tools to create and insert your citations in more styles than even imaginable.
