As a blogger who works online most of the time, it isn’t unusual to stumble upon my work published on websites that I never gave permission to reproduce my work. After all the painstaking effort put in especially in writing my web hosting review articles, it is annoying and frustrating to find my work being irresponsibly copied by other “writers” on other web hosting blogs. Plagiarism can simply be defined as the most “similar imitation” in which a particular work previously and originally done by an author is copied without the author’s knowledge or approval.

Fret no more for there are several good, reliable and free plagiarism checker websites to protect your hard work from being stolen. The top 10 plagiarism checker websites are:

  1. PlagiarismCheck

    The site provides free services such as the checking of an unlimited number of papers and the generating plagiarism reports. What is great about the website is that it accepts all kinds of file formats and it even offers simple and instant ways of downloading plagiarism reports from wherever your location is. However, the fast and smart online plagiarism checker does have its own downside: the products offered do not come with any warranty.

  2. Article Checker

    Unlike PlagiarismCheck where you’d have to register and upload your work beforehand, the Article Checker is amazing as it allows you to check your work directly and instantly by pasting your text/work to make a comparison. There isn’t a need to register or download anything. Check for any possible duplications within seconds, however the results may be dissatisfying at times.

  3. Plagiarism Checker

    This site is especially beneficial to authors and teachers/lecturers alike with different guides given to each author and teacher on how to use the product. At this site, you could check a document, web page, handouts and articles for duplicates and report any plagiarism detected immediately. Unfortunately, Plagiarism Checker doesn’t come free. Other plagiarism detection services are also available but you’ll need to buy subscription.

  4. SearchEngineReports

    This site is extremely simple and all you need to do is to paste your text/work in the text box to compare. The site currently has some unresolved issues with Bing with the latter throwing false plagiarized positives in certain situations.

  5. Tuition

    The site not only provides checking for any plagiarism in English but also provides a comprehensive range of private tuition, tutors and exam preparation services. Unfortunately, the site would most likely benefit only students from Hong Kong.

  6. DupliChecker

    The site offers free online plagiarism detection tool without any registration required. On top of that, DupliChecker also provides a lot of useful tips and information regarding plagiarism but it might take forever to read everything on this site though.

  7. Plagium

    Plagium is another plagiarism checker that is free for all to use. The checking algorithm scans the web and new for similarities and the users can opt to display the summaries, text found, timeline and/or real time results.

  8. Dustball

    The site practically works just like most other plagiarism checker websites. It offers basic checking services for free but if you would like to have more powerful detection at three times more accurate than the free version, you can sign up for the premium version at $8 per month.

  9. SmallSEOTools

    This is a site that provides a wide range of services other than just plagiarism checking. One can utilize the article rewriter tool and use the other features such as link tracker, search engine pingler, backlink maker and Google parerank checked. However, the plagiarism checker is pretty basic but thankfully, it’s free and everyone is welcome to use the product provided.

  10. DocCop

    The site doesn’t take any copyright or ownership of your material nor retains the contents of your files beyond the time taken to generate the report. However, the site is only able to support a few types of file formats, which include PDF and .docx.

All in all, the plagiarism checker websites mentioned above all have their very own pros and cons which you should take into consideration before you decide on the best site that suits your personal needs. If you’re a teacher or lecturer checking up on your students’ works, then opt for the site that caters to people of your profession. Meanwhile, if you’re an author, go for the site that includes or specializes in checking against commercial articles and handouts.

Your bio seems be showing up properly at the end of your guest post. Please let me know if I’m missing something.



Oh, I have a longer description about myself which I entered in my profile in the WordPress admin/dashboard? Sorry, I am actually at a shared computer, so might not be a good idea to login and double check.


Anil Agarwal

I just checked out, you have the same description on profile page as well. If you want me to change it, please email me your detailed author bio. I will add that to your guest post.



Oh, I saw the description at the end of the post. Sorry, I missed that earlier, because usually other blogs put that piece of info in the “Article by” box. :)



I use article checker – it seems the most user-friendly. Even if I try to express my own ideas, for sure that there are several other writers who has similar ideas, so it’s always best to be safe.



This is a great resource, it’s a good idea for content writers to check their work before submitting articles to websites.

Good work but only few of’em are useful for URL check, others are not even OK and they doesn’t seem to be a match of Copyscape or others.
