6 Best Plagiarism Checker Tools For Flawless Writing 1

It doesn’t matter if you are working on a homework assignment or writing a blog post, it’s important to make sure your content is plagiarism-free.

If you don’t know what plagiarism is, in simple words, it means copying someone else’s content without prior consent from the author or giving credit to the author.

Even if it were not your intentions to copy someone else’s work, you might have done that unintentionally in the past.

And no matter what field you are in, it’s not only unethical, but also a crime to copy someone else’s work and publish it as your own.

So, to save you tons of embarrassment and fines here’s a list of the best plagiarism checkers there are on the internet.

6 Best Plagiarism Checker Tools For Flawless Writing

If you are a blogger, I would highly recommend you to start using Grammarly today.

It is more than just a Grammar Checking tool.

It offers hundreds of features including:

  • Checks for over 250 Grammatical Mistakes.

You can use Grammarly for free (as a grammar checker), but if you want to use their Plagiarism Checker, you will have to pay for a premium subscription.

Grammarly is a great tool I recommend to everyone who has anything to do with writing.

I am pretty sure you have seen one of those “protected by CopyScape” badges on blogs.

If you haven’t, CopyScape is one of the oldest plagiarism checking tools on the internet.

It’s been around for a really long time.

One great benefit of using this tool is that, unlike its competitors, it doesn’t store the content you check on its servers.

While there’s a premium version that offers 3x more accurate results (as stated on the website), their free tool is pretty accurate and can detect most pieces of plagiarism in your content.

5. Plagium

It’s been online since 2006 and checks your content for free as long as you don’t make too many requests.

I hope these tools help you write better content, avoid embarrassment.

Most of these tools will allow you to check your content for plagiarism for free, but if you want better and accurate results, it’s highly recommended that you give their premium versions a try.
