Four free online plagiarism checkers

IJNet | November 17, 2015

“Detecting duplicate content online has become so easy that spot-the-plagiarist is almost a party game,” former IJNet editor Nicole Martinelli wrote in 2012. “It's no joke, however, for news organizations who discover they have published copycat content.”

When IJNet first ran Martinelli’s post, “Five free online plagiarism checkers,” two prominent U.S. journalists had recently been caught in the act: Fareed Zakaria and Jonah Lehrer.

Following acknowledgement that he had plagiarized sections of an article about gun control, Time and CNN suspended Zakaria. Lehrer first came under scrutiny for "self-plagiarism" at The New Yorker. Later, a journalist revealed Lehrer also fabricated or changed quotes attributed to Bob Dylan in his book, “Imagine.”

To date, Martinelli’s list of free plagiarism checkers has been one of IJNet’s most popular articles across all languages. It’s clear readers want to avoid the pitfalls of plagiarism, so we’ve updated the post with four of the best free online plagiarism checkers available to anyone, revised for 2015:

Grammarly

Grammarly gets points for its clean, easy-to-use interface and its efficacy as a plagiarism checker, which compares your writing to more than 8 billion web pages. To check any piece of writing for possible plagiarism, simply drag and drop a file or copy and paste your text onto the web page. Best of all? Grammarly isn’t just a plagiarism checker. The site also checks for spelling and grammatical errors and suggests optimal vocabulary words, allowing you to improve your writing. Grammarly is only available in English, which is one potential drawback for journalists who work internationally.

NoPlag

NoPlag is another great plagiarism checker that compares your writing to articles published online to detect possible cases of plagiarism. To use NoPlag for free without an account, you’ll be able to perform five plagiarism checks per day, with text samples up to 500 words in length.

Plagiarism Checker

Plagiarism Checker allows you to check writing samples up to 1,500 words in length for plagiarism. If your writing gets marked for potential plagiarism, you’ll be able to review the exact places in your writing that match with content found online.

CopyLeaks

Increasing demand

For the last decade the demand on plagiarism checkers have increased in 5 times. Many universities and colleges purchase such plagiarism checkers to insure that their students write their essays by their own. But this checkers aren't the final solution. They definitely show if the essays or assignments are original. But that isn't a guarentee that they are written by students themselves. Essay writing services flourish now, many of such services provide unique and custom content. You can check essay services reviews websites  like topreviewstars com for its proof. Sometimes it's hard to identify who is the author. In this way the potential of future graduates is decreasing every year.

From my experience, free tool

From my experience, free tool doesn't mean good tool. I used to check papers for plagiarism using free online checkers but the quality of their reports was extremely poor. Now I'm using Unplag, it's not free but this price worth paying for results. As a teacher, I care about the quality and safety of tools me and my students use.

I found one more

Plagiarism Tools

Superb Collection indeed! There are a few I have yet to try. There is however one
more tool, a project of mine, that I’d like to share with you – https://seotoolscheck.com/plagiarism-checker

Plagiarism checker

i think the best plagiarism checker is one which combines results of different search engines to provide you the best result. Also there sentences that cannot be replace so the plagiarism checker should not mark them as copied.

One of the seo tools website which combines google, bing and copyscape.

It is important for journalists to be truthful

Great list of tools, haven't heard about some of them yet. 
 
The journalist should care about the accuracy of his writing, and don't forget to cite the necessary parts of his articles. I use this plagiarism detection tool https://unplag.com before my articles go live. 

It's fast and accurate, and it's never let me down.
