We offer this website completely free to our visitors. To help pay the bills, we’ll often (but not always) set up affiliate relationships with the top providers after selecting our favorites. However, we do our best not to let this impact our choices. There are plenty of high-paying companies we’ve turned down because we didn’t like their product.
An added benefit of our relationships is that we always try to negotiate exclusive discounts for our visitors.

While it only offers a paid version of an AI/plagiarism checker, Originality.AI is an excellent plagiarism and AI detector.
With a 96% accuracy rate, it offers companies and individuals security that their content is not only original but also undetectable by Google’s algorithm. It helps you avoid getting punished for AI content.
On the other hand, Copyscape does offer a free version, which will appeal to casual and one-time users.
Our Verdict:
Though Copyscape offers a free version, the accuracy and range of services offered make Originality.AI the winner here.
Originality.AI also has very affordable options at just $.01 per 100 words, which we think is well worth it considering the accuracy of the results.
The team management tools offered by Originality.AI also make it more efficient for companies to use. If you don’t have the money, Copyscape is still an effective option.

A writer’s best friend, Grammarly offers a plagiarism checker with its premium subscription that rivals Copyscape’s.
We love Grammarly’s extension that detects grammatical errors live, of course, but the plagiarism checker is also worth mentioning.
The premium Grammarly subscription includes other useful features like fluency and tone detectors and citation checking.
Copyscape, however, offers plagiarism checking for free, while Grammarly’s plagiarism checker is limited to the premium subscription.
Our Verdict:
Copyscape wins this one in terms of plagiarism detection.
Not only does it offer a free plagiarism checker, but it also has Copysentry to actively check for plagiarism from your site.
Grammarly does offer features that Copyscape does not, however, so we still recommend at least the free extension of Grammarly for all writing tasks.

Plagiarisma is another great alternative to Copyscape. It’s a robust plagiarism detection tool designed with teachers in mind.
Plagiarism offers a variety of ways to access its services, including a user-friendly website and convenient plugins for Windows, Android, and Moodle platforms.
With its comprehensive coverage, teachers can easily check for plagiarism across various devices, ensuring academic integrity.
Copyscape offers fewer plugins but does have the unique Copysentry service not offered by Plagiarisma.
Our Verdict:
Plagiarisma wins this one but just barely.
The reason it comes out on top is that, like Grammarly, it offers advanced tools to help with other aspects of writing, including grammar, spelling, and tone.

Acting as a sort of personal writing assistant, ProWritingAid is a unique plagiarism-checking/writing improvement tool.
Not only does it check over 1 billion sources, but it also offers more advanced resources for writers, including masterclasses and writing tips.
Copyscape focuses more on just the plagiarism aspect of writing, which is better for folks who just need to know if they’re ripping off another piece of writing.
Our Verdict:
Copyscape wins for plagiarism detection, but ProWritingAid is a better all-around writing tool.
The advanced features like style suggestions and masterclasses make this a better choice for writing the next great novel. Even so, Copyscape offers more plagiarism detection tools.
