Grammarly as an online plagiarism checker

Grammarly is not only a tool for grammar checking but also an online plagiarism checker. Yes, Grammarly is an all-in-one tool that can do all sorts of checking for your text with seeming ease.


One thing to know that you can’t use the plagiarism detection option of Grammarly in its free version. You’ll have to go for the premium version for having everything including the plagiarism checking facility.

grammarly extension

As the premium version of Grammarly doesn’t cost much and you’re getting all the necessary things for checking your writing, moving to premium option won’t be a matter for you.


The best thing is that if you purchase the premium version of Grammarly, then you don’t have to use any other tool for plagiarism check.


Note that if you use Copyscape, then you still need another tool for checking your grammatical and other types of mistakes. So, Grammarly is the one-stop solution for checking your writing.


I should say that both Grammarly and Copyscape are good for plagiarism detection, but Grammarly will surely outshine its any competitor because of its multi-featured facilities.


Now, learn how to use Grammarly for the plagiarism check.


First of all, visit Grammarly (Click Here) [affiliate link].


Now, you’ll see the dashboard of Grammarly. You can input your document in three different ways such as writing, copy-pasting and uploading.


Look at this button –

new or upload

Clicking on the “New” button will open a blank panel where you can either start writing your text or paste your copied text.


On the other hand, you can upload your document by following the “Upload” button.


After setting your text now is the time to go for the plagiarism check option. You’ll have to hover over the following button –

From the button, you’ll need to opt for the “Upgrade for Plagiarism” option. Then you’ll see that your text has been checked for plagiarism and detected some plagiarized texts if there’s any.


So, using Grammarly is also very easy.



This is a free plagiarism checker tool which is much popular among freelance writing clients. This tool is free and at the same time, very strict in checking plagiarism.

Though many people rely on this tool, I don’t like this too that much because sometimes, the result comes from this tool is totally absurd.

So, SmallSEOTools can be another choice at the time of checking plagiarism.



You can’t mark this tool as a plagiarism checker free online, though the tool offers you a free trial. So, you can try the tool for free just by signing up on their site.

There are also pricing variations for different categories.


There are many advantages of using this tool which is as follows –

All the plagiarism detection comes with highlighted text so that you can find that easily. The tool also offers fast review which saves time while giving robust plagiarism check.


Another good facility of this tool is that the checking process is completely run on its own server, so if you mistakenly close your browser, then the checking will be still continuing. This is a great benefit that I hardly see on any other tool.


Also, the storage has no limit, that means you can even store tons of checked docs on its server. It’s like your cloud storage that saves all your previously checked documents.


As the tool runs online, you shouldn’t have to worry about installing it on your PC or anywhere else though this facility is with all the online plagiarism checkers.


There are many other facilities which you could experience at the time of using the tool yourself.



This isn’t a free online plagiarism checker, so you can only use its premium version. Good news is that the cost of using this tool isn’t that much, so you can happily use this nice tool.

The DustBall project was launched by Brian Klug which is a successful one.


To use the tool, you’ll have to visit its site. After landing the homepage, you’ll see that there’s the option “The Plagiarism Checker” at the top of the site.

The tool also supports multiple languages, so you can use your native language if that’s available in the language support option.


One of the drawbacks of Plagium is that it takes much time to check even a short text. So, if your requirement is to check things blazingly fast, then you should never approach this tool.


Overall, the tool is very effective, so you can completely rely on this.



This tool is marvelous for rating your text and it’s common to know that plagiarism is one of the major considerations for being a highly rated text.


PaparRater is for checking your writing for so many things like grammar, plagiarism, punctuation etc. So, this is another all-in-one tool like Grammarly, Whitesmoke etc.
