2. Grammarly Online Plagiarism Checker
This is by far the best online Plagiarism checker tool which you can use. Grammarly is a well-known tool among writers and also who need to quickly check if the article is original or copied from other places.
If you are a professor and need to check if the research paper is original or copied from multiple sources online, this tool is perfect for you.

This is a multi-feature tool for webmasters to check the originality of the content, check Grammar, and Check the spelling of the article.

3. Quetext
Quetext offers free plagiarism checker as well as a paid option for checking more words. They scan websites, academic papers and books to find for duplicates. They also cite sources which help you to give credit to the original source in case if your author did not add it.

5. Plagium
This is my favorite site to quickly find if the content is original or duplicate. You can paste the content on the homepage and click on Quick search, and within seconds you will have the results with you.
6. Copyscape
Copyscape is one of the oldest and most popular plagiarism checker sites. Here you can find duplicate content by adding the URL. It’s fast and cheap. I’m not a huge fan of Copyscape anymore as the interface is quite old, and they have not even moved to HTTPS, which shows that the people behind Copyscape are not so serious about the tool.
However, for anyone looking to use a free plagiarism checker tool, Copyscape does the job well.
Well, I’ve just narrowed down my list to the top 6. I’m sure there are lots more out there. Let me know which one you currently use or intend to use.

Thanks again Shout me loud for this post.
At this time only a fool will not use a plagiarism checker! Previously I used Copyscape, but now switched to Unplag. It costs not much, but provides many different features, so it’s worth it.
Thanks again Shoutmeloud for this post.
I am a fan of grammarly, but I never used the web version, so I came to learn today about Grammarly’s this feature.
Smallseotools.com is also a great site to check this.
I’ve been a guest blogger for multiple outlets and after a simple google search, saw that some of my work was being plagiarised without my approval. I’ve started to use Copyleaks as it notifies me when others have used my work. Also very cost efficient for different price packages
Thanks, Harsh! Grammarly is an ultimate tool. After panda attack, I’m using this tool to rewrite my contents. Meanwhile, try using Ginger tool which also provides rephrase suggestions, which Grammarly can’t help.
Thanks for all the different options here. I am currently trying out copyscape, but will try the others as well. Once again, fantastic information!!
I never knew these tools until two months ago.
First time I checked my site for duplicate content and even I found duplicate articles in my own site, because I moved all content from blogger blog to WordPress.
Thanks for the list of good tools.
Hey, Mukund! Thanks for sharing!
At this time only a fool will not use a plagiarism checker! Previously I used Copyscape, but now switched to Unplag. It costs not much, but provides many different features, so it’s worth it.
But, anyway, you published an article about 10 tools… and which is the best even so? Which tool do you use for your content checking?
Copyscape and dupli checker seems to be simple….
Copyscape shows the duplicate content from your own website too…
Really helpful for checking the duplicate content!
I find a lot of people using Copyscape which is good but often fail to detect when a few words are tweaked or altered from an original work. To ensure that a work is unique, try entering it in paragraphs or simply divide it into chunks of three or four and check.
TFS the list. I do regular use copyscape for post publishing the content, but the other tools mentioned here could be used for pre publishing as well.
Thanks again.
These are really useful sites to check copied content. Well, I know about copyscape and it’s really a great tool, but it’s good to know more alternatives. Thanks Mukund for this useful post 🙂
I use Copyscape heavily on Guest posts and so should you. Kinda acts like a filter.
@shashank chinchli: Thanks for the comment buddy! Hope you enjoy the other articles as well!
@Asif Ahmed: Well, I’m on your side as well. I use the tools mentioned above to check the guest articles on my blog. Anyway, thanks for the comment Asif!
@rakesh: Well, why don’t you file a DMCA against such blogs, just in case, they don’t remove the article?
some of my contents were copied by joomla site running from USA. I could not do anything except, as we do not have any copyright on that article. Now they are enjoying my content. So what is the fun of these types of websites. We can only send mails to these webmasters and they really does not respond.
Bookmarked it, I have opened guest posting on my blog lately and Got few guest post. I tried searching for Good tools to check plagiarism but got only few. This list will help me Filtering the Good content for my blog. Thanks!
