Pros & Cons of Grammarly Plagiarism Checker

Grammarly plagiarism has numerous amazing qualities. Its major downside is however subjective.


1. Very Accurate

Thanks to its vast database of resources, Grammarly plagiarism can easily compare your essay or article with billions of already published works.

Besides offering impeccable checks, the app allows you to filter your content for grammar structure, passive voices, and readability. 

These features are only available in the premium version alongside the plagiarism checker.

2. Unlimited Checks 

With Grammarly, there is no limit to the number of writeups you can check for plagiarism as long as you are on a premium plan. 

If you are the type who constantly writes and publishes papers, this feature will save you a lot of money. 

On other plagiarism checkers, you are either required to pay per check or there is a certain number of words you cannot exceed.


1. Expensive

Grammarly’s plagiarism checker is a feature designed for premium subscribers. In other words, if you do not plan on spending money on a plagiarism checker, this may seem like a disadvantage.

For context, it costs just $30 per month to become a premium member or $12 per month if you prefer the annual plan. These fees are little compared to what you will be getting.

What Plagiarism Percentage is Acceptable on Grammarly?

As a writer or student, you need to know the standards when it comes to plagiarism. Once your content exceeds a 15% score, you will have to adjust it until it comes to a value below 15%.

15% or more plagiarism may result in sanctions because it means your article’s originality is not above 75%. I prefer an 80% originality score because it is a safe zone.
