  • Type of Plagiarism Detection- AI-powered plagiarism detection;
  • Works on Mobile- iPhone and Android;
  • Free trial Available- no free trial available;
  • Refund Available-  no refunds;
  • Coupon code- no coupon code.

Copyscape is one of the best plagiarism checker tools on this list. It’s the tool I use regularly to check the originality of my content, personally written and the one submitted to me by my freelance writers.

For example, here I checked my Jasper AI pricing guide in Copyscape and I found parts of my page duplicated on 2 pages, but one of them is my already published Jasper AI pricing tutorial.

Copyscape found plagiarized parts of my Jasper AI pricing tutorial

The way Copyscape works is that once you submit content to it (URL or text content) it scans its huge internal database to look for content that is identical or very similar.

And it shows you the percentage of content that’s the same as someone else’s. Copyscape also highlights the plagiarized parts of the content you submitted, as you can see in the image below.

Copyscape plagiarism checker shows you the percentage of duplicated content

Copyscape also lets you check batches of pages for added efficiency (especially helpful for huge sites). All you have to do is go to Copyscape Batch Search in the header menu.

You can submit your XML sitemap or a list of URL’s (up to 10 000 entries).

Who is Copyscape Plagiarism Checker Best for?

#3- Grammarly Premium Plagiarism Checker


Grammarly plagiarism checker app and tool

  • Name- Grammarly anti-plagiarism tool;
  • Type of Plagiarism Detection- AI-powered plagiarism detection;
  • Works on Mobile- iPhone and Android;
  • Free trial Available- free trial available only for Grammarly Business plan;
  • Refund Available-  no refunds;
  • Coupon code- no coupon code.

Grammarly is the world’s most popular AI writing assistant that checks your content style, grammar, spelling diction, punctuation errors, and all other types of writing errors.

Grammarly has an excellent extension for Chrome which enables Grammarly anywhere you write, be it Slack, Discord, Evernote, Gmail (Grammarly for Gmail guide) Microsoft Word, etc.

Besides being a comprehensive AI writing assistant, Grammarly is also a powerful plagiarism checker and a worthy addition to this list. They use Proquest’s database with more than 16 billion pages (and that number growing daily) to check against your content and find matches. If they do you get alerted and you can take the appropriate action.

The Grammarly plagiarism checker is free to use, however, the drawback is that it won’t show you where and how you’ve plagiarized. So it’s kind of a teaser for Grammarly premium.

Here I tested some content from my blog and Grammarly correctly flagged it as duplicate. But then they urged me to open an account to see how much of the content is plagiarized and from which sources exactly.

You need to sign up to Grammarly Premium to use their plagiarism checker

So, if you aren’t just looking for a plagiarism check but need an AI assistant that can check your writing and all mistakes you can make, then go for Grammarly Premium (Grammarly plans and pricing explained) and you won’t regret it.

It’s an excellent tool.

Grammarly Pros ( What I Like)

  • Decent plagiarism checker;
  • (limited) free plagiarism checker is available;
  • a huge database of over 16 billion pages to scan for plagiarizing;

Grammarly Cons (What I Don’t Like)

  • Not a free plagiarism checker;
  • Support could be improved;
  • Grammarly as a plagiarism checker fails to detect heavily paraphrased content. In my experience Grammarly especially struggles with Quillbot paraphrased content.

Who is Grammarly Plagiarism Checker Best for?

Grammarly’s anti-plagiarism checker is available only with Grammarly Premium.

That is why I recommend Grammarly as a plagiarism checker only to those people who want to buy Grammarly because it’s an excellent AI-powered writing assistant (that happens to come with a decent premium plagiarism checker).

I don’t recommend you buy Grammarly just because you need a premium plagiarism tool.

Instead, go for better and cheaper tools like Originality.ai instead.

Grammarly Pricing

Grammarly has 3 plans:

  • Free;
  • Premium ($11.66/mo);
  • Business ($12.50/mo).

To learn more about Grammarly check out my Grammarly free trial, Grammarly student discount, and Grammarly military discount guides next.

#4- Quillbot Plagiarism Checker App


Quillbot plagiarism checker app and tool
Quillbot plagiarism checker app and tool

  • Name- Quillbot plagiarism detection tool;
  • Type of Plagiarism Detection- AI-powered plagiarism detection;
  • Works on Mobile- iPhone and Android;
  • Free trial Available- no free trial.
  • Refund Available-  3-day refunds;
  • Coupon code- coupon code= GOPREMIUM.You get a 20% discount on yearly Quillbot plan.

Besides being a content paraphrase and summarizer, Quillbot is also a plagiarism checker.

To access it you need to go to Quillbot.com, then to Plagiarism Checker, and paste your content. Hit check and Quillbot will check your content for plagiarized content.

For example, here’s how I checked my Quillbot discount code tutorial.

You can see in the right sidebar Quillbot found several pages that copy parts of my page.

Good job.

Quillbot AI anti plagiarism app found all instances of the page it checked

Detecting clear content duplication is something all plagiarism checkers on this list can do. It’s easy and basic.

Let’s see how Quillbot handles content paraphrased with Quillbot (how meta!).

I’ll take a few hundred words from my guide on the best Quillbot alternatives and paraphrase it with Quillbot.

Quillbot paraphrased content ready to be tested for plagiarism

Now I’ll test the paraphrased output Quillbot gave me with Quillbot Plagiarism Checker.

Testing Quillbot Plagiarism Checker app 1

And here are the results:

Quillbot paraphrased content passes as original in Quillbot plagiarism checker app

As you can see, Quillbot paraphrased content passes as original inside Quillbot Plagiarism Checker.

You can look at this in two ways. First, Quillbot Plagiarism Checker sucks!

Second, Quillbot’s paraphrased content is undetectable.

Quillbot Plagiarism Checker Pros (What I Like)

  • Decent plagiarism checker;
  • a huge database of billions of pages to scan for plagiarizing;

Quillbot Plagiarism Checker Cons (What I Don’t Like)

  • Not a free plagiarism checker;
  • Support could be improved (only email support available);
  • very expensive (Quillbot’s plagiarism checker is the second most expensive tool among all other plagiarism software in this guide);
  • very slow- it takes more than 5 minutes to scan ~500 words.
  • In my testing couldn’t detect Quillbot paraphrased content;
  • Not available as a standalone tool
  • Low usage quota even after you pay (only roughly  5 000 words before you have to buy additional credits).

Quillbot Plagiarism Checker Tool Pricing

Quillbot Plagiarism Checker is not a standalone tool. Instead, you get access to it with Quillbot paid plans (monthly, semi-yearly, and yearly).

When you purchase any of the Quillbot Premium plans (check out my Quillbot cost guide here), you get 20 pages to check for free. One page of content equals 250 words of content. This means you can check up to 5 000 words of content before you need to upgrade.

This isn’t that much when you think about it, but you can easily purchase more pages (though I don’t recommend it).

Additional pages cost for Quillbot Plagiarism Checker App:

  • $7.45 for 25 pages;
  • $24.95 for 100 pages;
  • and $49.95 for 250 pages.

Who is Quillbot Plagiarism Checker App Best for?

In my honest opinion, Quillbot Plagiarism Checker App is very expensive and not worth getting as there are many other equally good online plagiarism checkers.

However, if you already have a paid Quillbot account then you should use it to check for plagiarism until you run out of credits. Afterwards, don’t buy new credits as it’s expensive. Instead, use a tool like Originality.ai which is equally good, and several times more affordable.

You can learn about Quillbot by reading my review of Quillbot, my Quillbot AI free trial, and my Quillbot pricing guide.

  • Works on Mobile- iPhone and Android;
  • Free trial Available- no free trial available;
  • Refund Available-  available;

Next, Scribbr will scan your document against 99.3 billion web pages, 8 million publications, and over 20 languages. And then you’ll get a result.

I gave Scribbr Word doc with my Originality.ai coupon code article and sure enough, Scribbr found the content to be duplicate.

Scribbr free plagiarism checker found duplicate content on a submitted web page

Note: as you can see, Scribbr’s free plagiarism checker is actually a tease of what their pro tool can do.

You don’t get a percentage match, or source URL and to see that valuable info you need to pay. And look, Scribbrs is asking I pay $19.95 for one document scan.

Scribbr asking for money to unlock full plagiarism report.

That’s crazy!

For example, I could use Originality.ai to scan the same page for a price of a few cents (it cost me just 8 credits for both AI and duplicate content scans).

On the other hand, Scribbr is by far the most expensive anti-plagiarism tool on this list and I don’t recommend it 99% of bloggers and web publishers.

You don’t need to pay so much money to get your content checked for duplication.

  • Third, prove you’re human and not a robot.
  • Fourth, get your results.

Duplichecker free plagiarism checker

The limit of text you can check at once is 1000 words. This is very generous given Duplichecker is a free service. The drawbacks of Duplichecker are that the tool is slow at spitting results and the website is loaded with ads.

I use an adblocker which blocks most of the ads, but take a look at how the page is inundated with them when you don’t use an adblocker.

Duplichecker free plagiarism checker homepage full with ads

The tool still work, but it’s very distracting.

Duplichecker Plagiarism Checker Pros (What I Like)

  • Free service;
  • Intuitive dashboard that’s easy to use;
  • Unlimited use during the day.

Duplichecker Plagiarism Checker Cons (What I Don’t Like)

  • Pretty basic duplicate content checker and definitely not the best on this list;
  • Negligible customer support (you can reach them only via the contact page in the footer);
  • Website full of distracting ads, unrelated to plagiarism, paraphrasing, or anything similar;
  • 1000 words limit per check.

Duplichecker Plagiarism Checker Pricing

DuplicChecker Plagiarism Checker has 3 payment levels:

  • Weekly- $5/wk;
  • Monthly- $25/mo;
  • Yearly- $110/yr

Note: Duplicekcer premium plagiarism checker gives you up to 25 000 words to scan at once and the plagiarism checks are really deep and more likely to find duplicates on the web.

However, I don’t recommend you get a premium version of DupliChecker simply because a tool like Originality.ai is much more affordable and equally good, if not better (Originality.ai is the number #1 tool on this list of best plagiarism checkers.

That is not an accident).

Who is DupliChecker Plagiarism Checker App Best for?

DupliChecker plagiarism checker app is a free tool and I recommend it to anyone who can’t afford a premium anti-plagiarism tool.

I don’t recommend Duplichecker to anyone who can afford a paid plagiarism checker. Paid tools are simply far more reliable and trustworthy.

The most affordable and also the best plagiarism checker on this list is Originality.ai. Pricing is 1c per 100 words checked for plagiarism. That’s very affordable.

Best plagiarism checker tools and apps for 2023

The best free plagiarism checker is Duplichecker.

Read below how to use it.

First, go to Duplichecker.com

The limit of text you can check at once is 1000 words which is very generous. The drawbacks of Duplicchecker is that the tool is slow at spitting results and also the tool is loaded with ads.

I use an adblocker which blocks most of the ads, but take a look at how the page is inundated with ads when you don’t use an adblocker.

Duplichecker free plagiarism checker homepage full with ads

The tools still work, but it’s very distracting.

#3- What is the Best Plagiarism Checker Tool That Can Also Rewrite Content?

The best plagiarism checker tool that can also rewrite content is Quillbot. Besides being a plagiarism checker Quillbot is also an excellent content paraphraser and summarizer.

Content summarizing is truly free and there is no paid plan while paraphrasing content is also free but a paid plan is available to unlock additional paraphrasing modes.

You can read my Quillbot AI review to learn more about it.

#4- Can Plagiarism Checking Tools Detect AI Content?

Tools like Jasper AI (review), Quillbot, Writesonic, ShortlyAI, and others boast about giving unique content that can’t be detected by any plagiarism software.

This means plagiarism checking tools won’t detect AI-generated content if the AI tool you used gave you 100% original content.

However, generative AI content can be detected.

For example, Originality.ai is a tool built for AI content detection. You can read my Originality.ai review Originality.ai pricing and my Originality.ai coupon code guides to learn more about it

And there are also other tools that claim to be able to detect all GPT types of AI content.

Check out my guide to the best AI content detection tools to learn more about them.

Pro tip:

Don’t think that you can use Google Bard, OpenAI ChatGPT, Microsoft Bing and Anthropic Claude to generate “unique” content that passes plagiarism checks.

OpenAI ChatGPT, Bing Chat, Anthropic Claude and Google Bard all use different (but similar) generative AI technologies to generate content that’s technically unique but ultimately highly derivative of the content the chatbots were fed during their training.

To learn more about Google Bard, make sure you read my Google Bard statistics guide next.

To learn more about Microsoft Bing, make sure you read my Bing Chat statistics and Microsoft Bing statistics guides next.

To learn more about OpenAI ChatGPT, make sure you read my ChatGPT statistics and OpenAI statistics guides next.

#5- Can Deliberately Making Grammar Errors Beat Plagiarism Checking Tools?

Deliberately making grammar errors can’t beat plagiarism-checking tools.

These tools are sophisticated and can deduce what the wrongly spelt word was supposed to be.

I don’t suggest you submit any content that’s riddled with typos and spelling errors. To make sure you don’t check out my guide to the best grammar checkers now!

#6- Can Plagiarism Checker Tools be Beaten by Online Paraphrasing Tools?

Online plagiarism checker tools can be beaten by online paraphrasing tools.

But it’s not that simple.

Don’t be surprised your content gets flagged as duplicated if all you did was use a simplistic content spinner to switch this word for that word, this synonym for that synonym,

But if you use a pro paraphraser which can change both the words and sentences while preserving meaning, then you’re in the clear.

If you’re interested in paraphrasing software that can do that for you check out my guide to the best online paraphrasing tools next.

 #7- What is the Most Accurate Plagiarism Checker?

The most accurate plagiarism checker on the market is Scribbr. Scribbr is so accurate because it is powered by Turnitin, the tool professors use to check their student’s work for plagiarism and academic dishonesty.

The problem with Scribbr is that it’s a very expensive tool. You need to pay $19/95 per document scan.

There are plenty of websites that check for plagiarism.

In my list here I’ve singled out the best plagiarism checkers on the market.

  1. Hi Nikola,
    I actually use Quetext, it’s pretty thorough and has caught a few things that Copyscape didn’t.

    One thing is it’s a little too thorough. During a check, I found some false positives, one of which linked to a report on Mongolian food exports. My niche is the farthest thing from Mongolian food exports, FYI. Great article!
