12 Free & Paid Services To Check For Plagiarism


Every work has a plagiarism rate, and it’s your responsibility to make sure that you are not caught for an excessive rate of plagiarism in your work. Here are a list of features to look out for when deciding which plagiarism tool to use and 12 tools for you to explore.


The interface and the ease of use are highly correlated to the price you pay. If you don’t mind pop-ups and paid ads, then a free service might be worth a shot. Though, it definitely doesn’t add trust and credibility when you know that a service makes money by making people click on their ads and not by doing a proper job checking papers for plagiarism.


Free services might not always be online. Their servers might crash and you won’t be able to check your work. You can always go to a different free service though.


Clearly, paid services are more accurate and up to date. You just call customer support if something is not working and that’s it. That’s the beauty of paying for something that you could otherwise use for free. It’s totally up to you. You just decide if you are willing to pay for guarantees and live support.


There are certain services that occupy the golden middle. They are neither free, nor expensive. Their prices are reasonable as to what you would expect to make sure your work is original. You have to be careful though, as some of these services are for professors only and would get your work submitted into a database. You would want to avoid that, as you work would no longer be original, once it’s in a database.

Free services:

  • Dustball
    Dustball can be used for free, but you could also pay $8 per month for premium for up to 50 uses.
  • Dupli Checker
    Dupli Checker is a free service oriented on postgraduate students.
  • PlagScan
    PlagScan can be free, but there are also pricing options for those who feel that they need more than a free detector. They can pay $16 per month, $13 per 50 000 words. The search is conducted online, and you can also get an app of the service.
  • PlagTracker
    PlagTracker is a plagiarism checker that will check the entire Internet and their own database to ensure the paper you are working on is plagiarism free.
  • PlagiarismChecker
    PlagiarismChecker allows you to enter phrases from a students’ paper and returns search results from Google.
  • Plagiarisma
    Plagiarisma is a free download that you would use locally on your computer.
  • Plagiarismsoftware
    Plagiarismsoftware accepts only notepad files (.txt) so you would have to copy your essay or whatever you’re checking to a text editor and only then paste it into the checker.

Paid services

  • Turnitin
    Turnitin is a platform for submitting feedback on students’ work. It is also a service that most professors use, as the system submits the work into a database, making it impossible that someone else will ever use the work again. It will have already been in a database, and thus it will show as plagiarized. 1 paper credit costs $7.95 and the service is one of the pricier options.
  • PlagiarismDetect
    PlagiarismDetect costs either 10 or 50 cents for one 275-word page checked. The price depends on the pricing plan you choose. It can be either standard or premium. Either is fine, and the standard option should be good for all practical purposes.
  • Canexus
    Canexus requires you to pay a one-time $30 fee. You get to use the service for an unlimited amount of time.
  • WriteCheck
    WriteCheck charges $8 per 1 paper, $30 per 5 papers or $100 per 20 papers.
  • CheckForPlagiarism
    CheckForPlagiarism charges $5 for 5 documents checked or $40 for 15 submissions.

I work as a copyright consultant investigating plagiarism cases on the internet. Cooperation with the companies who develop plagiarism checkers (software and online ones) and educational institutions has brought me great experience, which I would like to share with community. At this point of time we can observe the increase of plagiarism cases, which clearly means that both students and teachers need to know more about it.
