A plagiarism check for peace of mind

Plagiarizing the works of another writer is a big deal in school and in life. The first step to avoiding it is knowing what it is.

One plagiarism definition is to steal somebody else’s words and pretend they are yours or to use someone else’s words and not give them credit. While this definition labels such actions as intentional theft, they can sometimes be accidental — innocent oversights.

Most teachers ask you to cite the works of others so you learn to be an ethical researcher who does not plagiarize. However, with so many assignments, chores, friends, and other parts of life going on, it can be difficult to keep track of everything.

That’s why using a plagiarism checker can save you from forgetting to cite sources. It’s simple to use and can make the difference between a stellar and a failing grade.

Easy citation creation

Let’s be honest, citations are a hassle. Nobody knows that better than we do; in fact, it’s the reason we created Citation Machine Plus! We wanted students and authors to have a one-stop shop when it comes to citing—a citation creation tool at your beck and call.

And now you do!

In addition to our paper checker, we have citation tools! Citing sources not only makes your work more professional, it is generally required for any formal papers or research projects. Any time you use the words or direct concepts of others, it’s vital to give credit where it’s due, and a proper citation is the means to do that.

Our program makes it easy as pie to type in the title or ISBN of your book and instantly create a correctly-formatted citation for APA format or MLA format citation styles. ** We have completely taken the hassle out of citing your sources, and—trust us—you will notice the difference.
** The APA and MLA are not associated with Citation Machine, but our citation services follow their styles.

Why Citation Machine Plus is the answer to your writing problems (well, mostly…)

Hypothetical situation (or is it?): You have just finished writing a paper for class. Maybe you spent hours writing it, maybe you only spent an hour on it. Either way, wouldn’t you feel better turning in your paper if it was proofread and reviewed first?

Everybody wants an A+. The only way to get there is through practice, hard work, and learning. Citation Machine Plus’s online grammar checker and spell checker can help you develop your writing skills by identifying potential errors in your paper. That way, you can simultaneously improve your paper while learning what grammatical points to focus on in the future.

Maybe you didn’t even know there was such a thing as an online grammar check and spell check program. But you do now!

Citation Machine Plus lets you perform a free grammar check on any text you plug into our smart proofreader box. A simple copy and paste or paper upload, a few clicks, and it’ll start reviewing your paper. Is an adjective used incorrectly? Is a determiner in the wrong spot? We’ll highlight any errors, plus more! In fact, Citation Machine Plus can sometimes even tell you why your mistakes are mistakes and help you correct them.

As it’s more than just an essay checker, Citation Machine Plus has a few more tricks up its sleeve! As the name implies, we are built for equipping you with simple, easy-to-use citation tools to help you build a bibliography for your paper.

You need MLA format help? We got you covered! How about APA format instead? No problem! We’re all over that, too! In fact, we have many more styles.

In addition, Citation Machine Plus can help you look for passages that might contain plagiarism. As we mentioned above, that’s when someone tries to pass the ideas of others off as their own original concepts or ideas.

Remember the Golden Rule? Do unto others as they would do unto you? Most of us would not want others to take credit for our ideas, so we don’t intentionally steal someone else’s words. But with so much information in the world, it can easily occur by accident.

Unfortunately, it happens both intentionally and unintentionally enough that teachers often take student work and run it through a scan to make sure the content is original. That’s right, even teachers sometimes use online tools from a subscription-based or free plagiarism checker. That being said, no teacher really wants to flag any student’s paper, and no student wants to be flagged. That’s one reason citations are so important and a vital part of ethical research and writing.

Here’s a detailed article if you’d like to learn more about avoiding plagiarism.

So now’s the time to stop stressing over grammar, accidentally plagiarizing others, and citation concerns. Let Citation Machine Plus help you write well!

Whether you need a quick check of your conjunction, noun, or verb usage, a thorough plagiarism scan, or reliable help citing sources, invest in a subscription to what we believe to be one of the most user-friendly citation tools online—Citation Machine Plus!
