One of the most common problems teachers encounter is a high amount of plagiarized papers submitted by their students.

Luckily for them, there are a lot of free plagiarism software out there that will help users check their content.

You might be surprised, but people very often search for plagiarism detection software in Google.

These plagiarism checkers are usually paid but there are some free and freemium ones that are also useful.

Let’s see some of the best plagiarism checker tools on the internet, their features and how they work.

  1. Turnitin

Turnitin tool is among top of its class and is mainly used for teachers and professors.

In terms of complexity, it is among the most well rounded with options such as:

  • Add a comment (allow professor to add a note to the document)
  • Original insights (shows the blog on which student found data)
  • Feedback (feedback for section of text)
  • Engage students (gives professor chance to grade work).

After you check for plagiarism, you are able to upload a report with all the details that will help student improve its writing.

  1. Grammarly

Grammarly is a bit different as it isn’t mainly focused on plagiarism.

This tool allows you to find all the mistakes you have in your text. It works rather easily and you can get reports from the website in no time.

Grammarly makes it even better that the tool has extension that can be downloaded and used in Google Chrome.

After you copy paste the article, this plagiarism detection tool will return a list with underlined issues.

There are also explanations leading you through the process.

Of course, I wouldn’t be talking about this tool if it didn’t have plagiarism feature. It is a rather rudimentary option but it works well in combination with its grammar checker.

  1. Quetext

Quetext tool is a relatively new tool revolving around Deep Search Technology.

This is one of the most advanced systems I have seen and it is definitely something that seasoned professionals should at least consider.

Although Quetext has a free version, you have to have in mind that this is mostly a trial option.

You will get all the features if you sign in and create a paid account.

It allows you to upload several files at the same time, there is no limit to the number of documents you can check.

Quetext can support texts up to 25.000 words long, you can get files in PDF format and it can exclude sources you don’t wish to be checked.

  1. Duplichecker

Duplichecker is one of the best examples of free content checkers.

Like some similar, basic plagiarism checkers it works by inserting copy pasted text into an empty box.

After that, the online tool will do its search through the Internet and find all the sources that have something in common with your text.

Of course, it is a bit limiting with only 1.000 words you can put in. It also gives just the basic data without advanced information regarding your article.

  1. Plagtracker

Plagtracker tool comes in two versions: free and paid.

If you choose to use free, you have limit of 3 plagiarism checks over a month.

But that isn’t the main reason why you should give this plagiarism software a chance.

First of all, Plagtracker paid version is really awesome.

After doing initial check, it will present you with a percentage of plagiarism and also, precise sentences that were copied will be shown.

On top of that, you will also get a list of sources where these plagiarized sentences were found.

If that wasn’t enough, there is a live support for all those who paid for Plagtracker monthly subscription.

  1. Plagiarisma

Most of the tools on this list are used straight from the web – you enter a text and you get results.

Plagiarisma’s uniqueness is the fact that you can also download the software.

This is a great option for all those who do not have Internet available at all times but still need to do their routine plagiarism check.

Besides that, there aren’t many differences when it comes to Plagiarisma and other duplicate checker tools.

  1. Copyscape

Let’s finish with the most popular plagiarism checker in the world – Copyscape.

Besides the fact that it’s very precise, it has an amazing comparison feature which allows you to easily compare two pieces of content by copying them directly in the tool or by simply placing their URLs into Copyscape.

Aside from this, this plagiarism checker can help you with the following things:

  • Check your entire site with a click of a button (up to 10 000 pages at once)
  • Analyse your own content and search for duplicate issues within it
  • Ignore results from particular sites which you own or don’t want to be taken into consideration

My favorite plagiarism checker

To be honest, I haven’t used plagiarism tools for quite a while.

Have in mind that we all have different needs and while some will be satisfied with a basic version, others will required a more sophisticated software.

Every now and then I use a duplicate checker tool named Advego Plagiatus but given that it is in Russian, I didn’t want to include it in this review. Another solid plagiarism checker tool is SafeAssign Checker, you should give it a try too.

What is your own choice to check for plagiarized content? Which plagiarism checker do you use? Share it in the comments below!
