Testing the text from one of my newly written posts

Before we begin, there are quite a few things which we must keep in mind before finding the best plagiarism checker. The first thing is, a plagiarism checker is the best if it can check the newest possible writing and it can guide us to the original content. Considering that, I’m going to test a piece of text from one of my new articles and see which plagiarism checkers can detect the text.

The article I’m going to test is SwiftKey Keyboard vs Gboard and compare the functionality for each checker. The best Plagiarism Checker will most likely to show me the plagiarised text with the link, and hopefully, all of the checkers will be able to identify that. I’m using the scoring system which will give you an idea about the tool and its functionalities.

01. Plagiarism Checker by Small SEO Tools (free) | Score: 90

Plagiarism Checker by Small SEO Tools

Plagiarism Checker by Small SEO Tools

In my previous tests, Plagiarism got 70 scores, and at that time, the interface was different. Now they have updated the interface, and I must say they have improved the tool too. Plagiarism Checker by Small SEO Tools is one of the great tools, According to the tool, 83% of the content was plagiarised, and 17% of the material was unique. The best thing about this tool is, it gives you the options to compare the plagiarised text which mainly goes to google and searches the text, it shows you the website address of the original content in the second menu, and it shows the highlighted plagiarised text in the third menu. I have given 90 scores to this tool because it does not ask for any account information and the tool is free.


02. PLAGIARISMA (free) | Score: 50

PLAGIARISMA

PLAGIARISMA

I hate to say this, but PLAGIARISMA could not find the text at all. The tool has two options (Google/Bing), and you must select one, so the checker can check for the writing on the search engine. There is also an option to find the exact match or similar. Picking Google showed me that the text is 100% unique while selecting Bing showed me that the writing is 10% unique. I can understand that selecting Bing gives somehow accurate results but most of the people are always scared of Google. There is a limit on how many times you can check the content each day so make sure you are not splitting the text.

03. Grammarly (paid) | Score: 80

Grammarly

Grammarly

The tool is one of the great Plagiarism checking tools out there and my favourite too, but the problem with this tool is you can’t check the content for free. In the tests, Grammarly could find the real text within a couple of seconds, and it showed the text as 100% plagiarised with a link to the original text post. The paid version is $11 per month on annual plan and $29 per month on the monthly plan. The reason I have given this tool 80 scores is that the tool is paid so you can not check the text for free. You can check prices here.


04. DupliChecker (free) | Score: 95

Dupli Checker

Dupli Checker

The fourth plagiarism checker on the list is Dupli Checker. The tool is one of the best plagiarism checkers out there because it is fast, free, and up-to-date. The tool could find the text source and shows me a link to the post. If you want to compare the text, then hit the Compare Text button and it will download shows you the original page with red highlighted plagiarised text. Surely one of the great tools to try.

05. EduBirdie (free) | Score: 90

EduBirdie

EduBirdie

When I first wrote this article, the tool got 35 scores because it could not find the text, but I must say this time it could find the text and showed the source. The tool has improved, and the best thing about EduBirdie is it shows you every possible source which contains the original text. You can differentiate between sources by clicking on the show button.


06. quetext (free) | Score: 30

quetext

quetext

Oops! quetext missed the article, I think. The tool showed me that, the text was unique. The reason I have given this tool 30 scores is that it has a great interface and it displays the red highlighted plagiarised text when it finds anything.

07. PaperRater (free) | Score: 95

PaperRater

PaperRater

The seventh plagiarism checker on the list in PaperRater and I was satisfied with the results because in the tests I could see that 89% of the text was not real. It also showed me both possible links which contain the original content. You can hover to the source to see the highlighted text. Clicking on the source goes to the website straight away.

Check out: Grammarly vs Microsoft Word.

08. Plagium (free) | Score: 100

 

Plagium

Plagium

It is a great plagiarism checker and the way it handled my text was beautiful. It comes with two options “the web” and “news” with two buttons “Quick Search” and “Deep Scan”. Deep scan requires a free account sign up, but you can quickly search with the quick search button. In results, it showed the source of the text with the percentage of similar text. The other best thing about Plagium is it sorts all the source from most similar to less similar so you can get the most accurate result on the top. The checker got 100 scores because it sure is one of the best plagiarism checkers.

Final results

The final results are combined results for the previous test and this test. The score might be different because of the comparison with the old test.

Plagiarism Checker by Small SEO Tools 80
PLAGIARISMA 45
Grammarly 100
Dupli Checker 93
EduBirdie 63

In conclusion

Well, the results from plagiarism checkers are in front of you. The results table shows that in both the tests, Grammarly, Dupli Checker, PaperRater, and Plagium found the correct sources. Grammarly is a paid one, and if you don’t want to pay, then you can go Plagium, PaperRater, or Dupli Checker. The best practice I recommend is checking the content on all of these websites if you think your content is similar to others.
