What’s plagiarism?

This video will certainly let you know many things about plagiarism. I’m also elaborating the thing, so don’t worry.

Note that learning about plagiarism is important because of becoming aware of this thing. So, you shouldn’t skip this portion. First of all, learn about plagiarism and then know how to check and avoid it in your text.

Plagiarism means stealing others words and/or ideas and claim that those are yours. So, when you claim others writing and/or ideas as yours, then you’re going through plagiarism.


Plagiarism is one sort of theft and you should always be away from this illegal act. To bloggers, plagiarism is like a nightmare because many bloggers have already ruined their blogs just by plagiarizing others content.


There are couple of ways you can use others content on your blog or site which are the following –

  • First of all, you need to take the original author’s permission whether you can use his/her writing or ideas on your blog.
  • At the time of using others content, you must give the credit to the actual author of the work.


So, when you use some quote of others, then you must add the source link to that. Similarly, if you share some previously spread ideas, then you should also give the credit to its actual originator. These are all common ways of avoiding plagiarism even though you’re writing others words or ideas.


Suppose that, Neil Patel has shared an idea and then you can also spread the idea by telling that Neil Patel suggested that or gave this idea etc.


You may plagiarize both intentionally or unintentionally. So, it’s always suggested that you use a decent plagiarism checker to detect and then avoid plagiarized work (I’ll also mention some great tools soon).


Why do you need a plagiarism checker?

There are tons of writings on the internet. So, it’s very hard to find out whether there is any matching text available online.


It’s plagiarism checker that can check whether your text is okay from plagiarism or not. Figuring out the thing can confirm you that you’re using a fresh content.


These are the reasons of using a plagiarism checker.


Different types of plagiarism!

In the above video, 10 types of plagiarism have been mentioned. I hope that you could come to know different types of plagiarism just by watching the video, so the video is worth watching.

So, Copyscape has taken this prestigious place that when someone says that his/her content will be passed by Copyscape, then everybody becomes relaxed!


When I was a freelance writer, I also had to write the phrase that I would produce Copyscape pass guaranteed content for you. Not only is that all of my clients used to warn me that they would check my written articles with Copyscape.


Here’s a short cover letter of mine that I used to send to my prospective clients when I was a full-time freelance writer –

So, you can see that I had to mention “Copyscape pass guarantee” in my cover letter to make my clients worry-free about plagiarized content.


All these experiences just made me mad of the tool and I really bought some credits from its premium account. You need to spend per credit for per check. Each time, you can check up to 2000 words in total. The pricing of credits is also very cheap. You can buy 100 credits at $5 only.


So, spending only $5, you could check 100 times for plagiarism.


The use of Copyscape is very easy and you won’t have to learn the rocket science to use it. First of all, you’ll have to visit the website of this great tool. You’ll need to create an account, so use the sign-up button for registering for an account.


If you already have an account, you just need to simply log into that now. On your account, you’ll see that there’s an option for purchasing credits. You’ll have to buy some credits to check your documents for plagiarism as you don’t have any credit after signing up.


Click on this –purchase creditswhich will open up another window for buying credits. You’ll need to decide how many credits you’ll need to buy. To do this, put your required credits in the box

credits of copyscape

After deciding the number of credit now is the time to hit the continue button.

copyscape continue

If you wanna pay with PayPal, then you’ll have to buy at least 200 credits. The validity of your purchase will be for long one year. So, you can use the purchased credits up to 12 months.


Once you buy the credits, you now can start using Copyscape. So, how will you use the tool? Well, I’m showing you the easy process now.


On the account main page, you’ll see a box like this (I’ve snapped the left half portion) –

copyscape check

You can see that this is the box where you’ll have to drop your text or the URL having the text. After dropping your required text or URL, now you’ll have to hit this button –

premium search

You could see whether your text is plagiarism-free or not. There’ll be some preview texts with their source links in the plagiarism report page from which you could visit the source files.


You could also see the plagiarized portions of the source files from the report. This will help you determine how much your given text has been caught for plagiarism. So, the tool is quite effective and easy to use.


Grammarly Review

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 seaming 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 –

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 –

It’ll start analyzing your text for plagiarism detection. You’ll see that the tool is automatically scoring your text between 0 and 100. A score above 95 is quite okay to accept.

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.

Whitesmoke is going like Grammarly by offering its wide range of usability on different platforms. Yes, this tool can be used on a PC, online, on mobile, and as a Chrome extension.

You can see the number of words and pages by leaving your words in the box. On the left side of the homepage of this tool, there are some stats which reveal that this is an awesome tool in this field.


There you can see the number of users and checks from which you can conclude a great notion about it.


The tool has also there different premium plans which I think are quite reasonable. Note that the free trial also needs you to signup first for an account.


Here are the current premium plans of the tool –

  • Light ($5.99)
  • Standard ($9.99)
  • Premium ($25.49)


The primary paid version’s name is Light which is primarily for the beginners. It can check up to 20 pages of your document. There is no daily limit of the number pages. This means that you can consume all the 20-page check in a day or at a time.


The next pan is Standard which is for experienced customers. This plan will allow you to check up to 50 pages. So, by taking this plan, you can save some money on your purchase.

This plan is the best money saving option for you. So, you should go for this plan if you really wanna have the most discount on your purchase.

So, this is the minimalist way of checking your writing for plagiarism. You can also check a web page by dropping its URL in another box had on the site.


To use the tool, first of all, you’ll have to visit its site. Going the site, you’ll see that there’s a box after a few texts. You can also learn how to use the tool for the teachers and the authors separately from the knowledge base of the tool.


There are also many valuable blog posts available on the site, so you can garner many things from them.



This tool is good for the purpose, but I think that it’s over-priced. The tool offers a very in-depth review of your docs so that you can make sure that they’re free of copies and other issues.


So, using the tool paying a bit more isn’t a wrong decision too.


The tool claims that they have around 1 million students registered with their service, so this a large number of users who’re using this tool.


One thing that I should tell you is that the tool also adds the grammar check option for free with its basic operation. This is really great because you won’t have to use any grammar checker tool for the further check of your text.

You can drop the text of at best 1000 words because this is the limitation for 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 of 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.


DustBall Plagiarism Checker

Wow! What a fabulous tool this is! I’m really impressed with the layout of the site. The tool has two different options like free and paid and you can choose any of the options as per your requirement.


Though the free version of the tool is okay to use, you should upgrade to the premium one if you want better results.


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.


Now is the time to click on the button which will open up a blank box for checking your text. You can check your doc in three different ways such as typing, pasting and uploading.


You can upload MS Word file to this tool so that you can check it. Though the tool can be used for free, you can have more accurate results with its premium version.


The cost of the tool is very cheap and it’s only $8 per month. So, you can try the premium version of the tool too as it doesn’t cost much.


This is the link to the tool, DustBall.



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 chek 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 to 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.


But to avail all the awesome features of this tool, you’ll have to go for its premium version. The premium version of PaperRater doesn’t cost much if you buy it for annually.


The current monthly price is only $7.95 if you buy the subscription on a yearly basis. The total one-time payment for a year comes to only $95.40. On the other hand, if you buy it for per month basis, then the charge will be $14.95 per month.


Going for the premium option is a wise decision not for only saving money, but also unlocking so many exciting features.


So, if you use PaperRater, then you won’t have to worry about using other tools for different checks such as punctuation, grammar etc.



Viper has given a nice touch in 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.


However, you’ll surely find the tool a nice one after installing and at the time of using it on your PC.


So, visit the site right now and you’ll see the “Download” option on 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).


It also supports a lot of many other things like WaterMarker, Copyright Bar, Facebook WaterMarker etc. There’s also WordPress plugin available for your WordPress blogs.


All of the premium services will need you to pay as low as $10 per month. By paying $10, you’ll get many of the premium facilities up to one year.


So, this is another great tool that should attract your attention for sure.



This is another tool which needs to be downloaded and installed on a PC before using it. So, first of all, go to the site of this tool and download it on your PC.

This the current plan price. So, you should visit the site yourself to check whether the price has been changed or not.



This tool is very helpful in shaping your text so that you can rank it well on SERPs. If your blog is arranged with plagiarized material, then you shouldn’t expect to rank that. There’s potential risk of getting your blog penalized too.


So, copied content is always hated and to check whether your text is okay or not, WebConf can do so many things for you.


WebConfs comes up with so many great features that are too good to rank your posts within a very short time.

Truth be told, Copyleaks is a great tool for doing everything to ensure whether your text is plagiarized of not. This works fully on the cloud, so the cloud-based functionality has given this tool much more power than you can imagine.


The tool has different options for education and business, so you can choose your preferred one at any time. The education version has also different sections such as for schools, universities, and students.


Business version also offers two different options – one for the publishers and the other one for the SEO agencies. One cool thing about the tool is that it can be used on mobile platforms too. So, if you wanna use it directly on your phone, you can do so just by installing its mobile app.


Copyleaks also works on MS Word, so you can even use the tool while writing on MS Word. The tool isn’t free of cost though you can have a few credits per month for free every month. So, without spending, you can hardly use the tool.


To use the tool, you’ll have to sign-up on its site. So, first of all, visit the site (Click Here). Then, follow the signup button placed on the top-right corner of the site.


Signing up means that you have got an account on Copyleaks. Now you can use the tool.


The tool, Copyleaks, is a good tool, but this tool can only work for plagiarism which makes me a bit disinterested in it. Also, the fees are quite high to me in comparison to other multi-tasking tools like Grammarly, Whitesmoke etc.


By the way, if plagiarism is the only thing that you need for your writing, then this tool will be a solid companion for sure no matter how much you need to pay for it.


After the brief discussion of this tool, I think that you have already got a clear idea about it. The only thing that I can say is that this is a reliable tool when it comes to checking plagiarism in your text.
