Looking for that best Copyscape alternatives for 2021?

I covered your back!

In this article, I'm going to review and recommend the best alternatives to Copyscape (both free and premium alternatives).

Copyscape has been preventing content theft and content fraud since 2004. It helps bloggers and publishers to quickly scan and identify flawed, plagiarized content.

You can also create watermarks and add banners on your website to prevent theft or scraping of content.

As much as I like what Copyscape has to offer, you have to raise a fair amount of money to take advantage of it, which bloggers and publishers cannot.

Let's check out the best free Copyscape alternatives that are a blast.

Best Copyscape Alternatives 2021

1 Grammar: # 1 CopyScape Alternatives

Most of us know grammar as a tool that allows us to proofread our content and correct grammatical errors. But there's more to this fantastic grammar checker!

In addition to the grammar check, a powerful plagiarism detector is included.

Grammarly's plagiarism checker is available as part of the Premium package with additional features.

While the free plan helps you check and correct spelling and grammar mistakes, the premium version lets you experience the full power of grammar!

To use it, you need to enable it on the dashboard. It is ideal for students who have quoted too heavily from other sources. If you have freelancers writing on your behalf, this should be your tool as it can help you check grammar and plagiarism on the go.

As a blogger who outsources a lot of content, grammar is my plagiarism detection service, and it goes through all of the content before it is published.

I checked out Grammarly's Plagiarism Checker where I got real user reviews and opinions from writers and bloggers who use it. Be sure to read my grammar review here.

Top features:

  • Serves as both grammar checker and proofreader
  • Avoids wordiness
  • Checks the active and passive language
  • Sentence reformulator at your fingertips
  • Checks your content against 8 billion websites
  • Built-in citation generator
  • Available online (as a browser extension), as an MS Word add-in, mobile apps.
  • Trusted by brands like Dell and universities like the University of Phoenix, Illinois, to name a few.

2 ProWritingAid

ProWritingAid is a great personal writing coach that provides a complete writing experience. Needless to say, it's ours first choice for Copyscape alternatives!

This writing assistant software includes a grammar guru, writing mentor, and style editor as a single package. To complete the writing coach package, ProWritingAid has a built-in plagiarism checker.

I've written a detailed review of ProWritingAid along with all of its features and explained how they can help you speed up your error-free writing process. Make sure you check it out.

ProWritingAid Plagiarism Checker lets you compare your content against over a billion other published works, including academic papers and websites.

To use this add-in function, you must either purchase the Premium Plus version of ProWritingAid, which contains 50 plagiarism checks per year, or purchase the plagiarism checks independently in the premium version.

You can purchase packages of 10 checks, 100, 500, or 1,000 checks, depending on your check needs. The higher the package, the lower the expenses. However, I don't see a need to buy 500 checks if all you have to do is review a few research papers a year.

ProWritingAid has a user base of over 700,000, ranging from writers to copywriters to students, professionals and editors. You can sign up for free, but there are only 19 reports, 500 words at a time and only available online!

With ProWritingAid Premium, you can remove the limitations by getting the full processing power. When checking grammar, there is no limit to the number of words. You have the option to edit where you write and take advantage of other amazing features. You can choose between 1 year, 2 years, 3 years, or lifetime access.

Top features:

  • Best for creative writers such as screenwriters and novelists.
  • ProWritingAid how grammar works with google docs (so if you're someone like me who mainly uses google docs, this is for you!)
  • Fixes style issues when writing
  • Perfect whitesmoke alternative for writers
  • Word explorer and contextual thesaurus.
  • Available as desktop apps (Mac & Windows), browser integrations and MS Word add-in.
