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.


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).


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 –

plagiarism 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.


Article Checker

If you’re bored with so many tools having almost the same functionalities, then you can try Article Checker. This tool has some awesome options to check your articles or blog posts for different types of copied works.


Visiting the homepage of the tool, you’ll see that they’re claiming that you can get A+ by checking your papers. On the bottom of the homepage, you’ll see the checkbox where you’ll have to put the text that you wanna check for plagiarism.


You can drop the text of at best 1000 words because this is the limitation of word count per search. The tool really works beyond expectation. Yes, I’ve tested a short text and the result was presented in an awesome way.


There were the scores for unique and plagiarized portion in percentage. You can also see the total word count and characters in your given text.


The tool also shows the checking completeness in percentage. By the seeing this as 100%, you can make sure that the check has been completed in full.



This tool has different checking options such as the deep check, quick check, and file comparison services. There’s a blank box which is for checking your text for plagiarism.


To get the blank box, you’ll need to visit the site of Plagium. The charge of the tool to check your doc is very low. So, if you wanna check your file at a low fee, then this tool should be your perfect choice.


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.



Viper has given a nice touch to this tool. To use this tool, you’ll need to download it on your PC. So, if you wanna use it directly on your web browser, then you can’t do that in any way.

So, visit the site right now and you’ll see the “Download” option in the top-right corner of the site. By clicking the button, you could download, install and use it.


Note that Viper isn’t supported in some regions, so if you live in any of the unsupported regions, then it’s really a disappointing thing for you.


The tool is called Viper Plagiarism Scanner which is totally free to use. I think that this tool should get a lot of attraction because of its free offer and use as a browser-less tool.



On this site, you can check whether a text is copied or not just by leaving any site’s URL. You can also have a DMCA sticker from this site to stick on any online publishing.


The sticker is very effective in warning and avoiding many online thieves (LOL).
