As a blogger, content writer, teacher, or student, you probably know that plagiarism is unacceptable. Google frowns upon it too and can easily blacklist your site if they find duplicate text. That means loss of rankings, traffic, and sales. Who wants that?
Luckily, Copyscape comes in to help you check your content against billions of similar pages on the internet. If there are any matching sources, the app will show you not only the matching text, but also the source it matches with online.
The plagiarism tool offers a free service that allows you to paste a URL and check for any duplicate content online. There’s a Copyscape Premium that lets you paste text or upload a batch of files and check for plagiarism. Furthermore, you can create a private index to let you check new content against what’s in the private database.
The other product is Copysentry that protects your website against content theft. The tool works by monitoring the internet for your content’s copies and emails you whenever new copies show up.
I like Copyscape because it’s fast, easy to use, clean (no ads), supports most of the popular languages and alphabets, and checks content against almost the entire internet.
However, there’s no way to verify whether the app has thoroughly checked all the revealed sources. Moreover, it can’t save plagiarism reports, doesn’t support cloud platforms like Google Drive, and their customer support is slow.
These shortcomings may prompt you to look for Copyscape alternatives. Keep reading to discover the best tool for your needs.
Best Copyscape Alternatives
1. ProWritingAid
You might know ProWritingAid as one of the best grammar and proofreading checkers.
But it also features a plagiarism checker that checks your content against more than a billion web pages to ascertain its originality.
While it doesn’t come with a free version it’s an affordable Copyscape alternative.
Here’s why: you’re billed based on the number of checks rather than the number of words. That means you can check high volume texts like novels and eBooks without paying much.
You pay $10 for 10 checks, $40 for 100 checks, $120 for 500 checks, and $200 for 1000 checks.
As a premium user, you can generate plagiarism reports and access other tools, such as grammar checker, thesaurus, readability reports, and more.
Moreover, the app is easy to use and compatible with tools like MS Word and Google Docs.
Now take your writing to the next level. ProWritingAid offers a robust grammar tool together with an easy to use style-editor, reports, articles, videos, quizzes and more!
2. Grammarly
Grammarly’s Plagiarism Checker compares your content against more than 16 billion web pages plus academic papers within Proquest’s databases. When a section of your text matches the content on web pages or in a database, you’ll receive a plagiarism alert.
The free version displays the number of grammar issues in the content and whether it’s plagiarized or not. But it doesn’t show you where the issues are.
The plagiarism checker in Grammarly Premium highlights the plagiarized sentences and displays the percentage of plagiarism in each.
Besides, you can see the sources of matching content on the right panel in the form of web URLs. You can click those links to dig deeper and confirm the details. As you rewrite the plagiarized content in the Grammarly interface, the highlighted sections will disappear.
In addition to checking for plagiarism, Grammarly is a grammar and spelling, and punctuation checker. So, while rewriting any unoriginal content, the tool also shows grammar errors in your content with suggestions on what to do. This is one of the features you won’t find on Copyscape
You can use the free version to check for plagiarism, but it only says whether the text has plagiarism or not. It also displays the number of writing issues in it.
To see the specific unoriginal text and other grammar errors, you may need to upgrade to the Premium Plan that starts at $12 a month or Business Plan that starts at $12.50 a month.

Teachers, SEO writers, businesses, bloggers, students, and anyone else use Copyleaks to check for duplicate content and plagiarism.
Copyleaks uses AI and machine learning technology to analyze manipulated text and spot identical, similar, and paraphrased sections of the content. This tool finds what other plagiarism checking tools let slip through the cracks.
What I find impressive about Copyleaks is the ability to generate accurate and comprehensive results as PDF reports. This is a feature you’d be hard pressed to find on Copyscape.
The CheatSpot.AI feature allows teachers to receive alerts when there’s suspected cheating. This feature uses White Ink and Character Development methods that lack in most plagiarism checkers.
Bloggers can use Copyleaks to compare individual webpages on two different websites to detect possible copyright infringement.
But that’s not all. Online course instructors can integrate Copyleaks with their favorite learning management system (LMS) in less than 30 minutes to help check for plagiarism and duplicate text right within the LMS.

10. Plagscan
Plagscan is probably one of the most advanced plagiarism checkers out there. Why do I say this? Its reports are comprehensive and organized.
The tool provides a source list where matches are categorized according to their sources. For instance, you’ll know if the match is from previously submitted documents, from the web, the Plagiarism Prevention Pool, or your company’s repository.
It’s also easy to read and understand the plagiarism report, as matches are highlighted in different colors. Green indicates detected citations, blue shows potentially modified content, and red shows the exact matches with their sources.
Highlighting reports in different colors isn’t available on Copyscape, making Plagscan a better alternative that gives you more organized and easy to understand reports..
Plagscan features a side by side comparison tool that lets you compare your document and the discovered matches. Simply put, you can see a match and its corresponding source in one clear view rather than switch between different windows.

There’s an option to choose the English language for checking your document. You can choose U.S. English, UK English, CA English, and AU English.
