What is Turnitin?

Founded by John Barrie and Christian Storm in 1997, Turnitin is text-matching software that spots plagiarism in written projects submitted online. The tool scans everything for text matches and compares it to a database of billions of files. It’ll highlight text if it’s copied from another source or isn’t cited correctly.

TurnitIn is only available via academic institutions, but you can still use its plagiarism engine via Scribbr. For the purpose of this comparison, I’ll focus on that version.

Who Is Grammarly And Turnitin For?

Grammarly and Turnitin have the same goal – to help people write better and avoid plagiarism penalties. However, they are suited to different audiences. Grammarly is for professionals, bloggers and freelancers who use the written word regularly. Turnitin is aimed solely at students and those working in academia, checking essays for plagiarism and other issues.

Grammarly Vs Turnitin: Our Tests

We’ve tested multiple articles in Grammarly and Turnitin while comparing their pricing, ease of use, and additional features.

Ease Of Use

The first factor I considered when testing Grammarly and the Scribbr interface powered by Turnitin is the ease of use. After using both tools, I can safely say that Grammarly and Turnitin offer a straightforward experience with little learning curve.

The size of a tool’s database is the most important factor to consider when shopping for plagiarism software. The more articles you can compare your work to, the better your results will be. When pasting this published Copyscape vs Grammarly comparison into Grammarly, it gave me a score of 60 percent. It found the article on Become a Writer Today, without issue.

Grammarly: Accuracy

Since I’m not a student or university instructor, I couldn’t sign up for Turnitin to check this article, which is one of the big drawbacks. However, I was able to test its plagiarism checking engine through Scribbr. When pasting the same article into the Turnitin plagiarism engine, I got a 99 percent score. 

Scribbr: Accuracy

Alongside scanning online scanning articles and blog posts, Turnitin has a far larger database than Grammarly. It also scans and checks works against academic papers and other gated resources. It also scans against content published in 20 languages, while Grammarly focus on English.

Winner: Turnitin


Free Plans

Grammarly provides an attractive free plan that lets users utilize handy features like the proofreader and weekly email feedback. This is perfect if you aren’t willing to invest in Grammarly Premium immediately and want to get a feel for the platform.

Even though there are scanning limitations, it’s still better than Turnitin because Turnitin doesn’t offer free plans.

Winner: Grammarly

Premium Plans

With Grammarly Premium, you can choose between three pricing options:

  1. $29.95 per month
  2. $59.95 every three months
  3. $139 per year

Unfortunately, Turnitin doesn’t have individual plans, and only schools and universities can buy their products. So if you’re representing a university, submit a request on the Turnitin website, and they’ll get back to you in three working days. 

But if you’d like to use the Turnitin plagiarism engine, consider Scribbr. It’s powered by Turnitin and has three plans:

  1. A small document up to 7,500 words costs $19.95
  2. Medium documents consisting of 7,500 words to 49,999 words cost $29.95
  3. A large document of over 50,000 words sets you back $39.95

However, this is quite costly, and you can check an unlimited number of words with Grammarly Premium.

Winner: Grammarly 

Additional Features

Here are some additional features that Grammarly and Turnitin provide:

  • Grammarly has a mobile app
  • Turnitin offers a more engaging student experience

Grammarly Supports Mobile

What stood out to me about Grammarly is the user-friendly mobile app that allows you to check for plagiarism on the go. Most plagiarism tools like Quetext and don’t do this. So if you work on your phone a lot, try Grammarly.

Turnitin Offers A More Engaging Experience Student Experience

Although Grammarly helps 94 percent of students better their grades, it doesn’t come close to the Turnitin experience. 

Turnitin has an interface similar to Notion, where teachers and university reviewers can guide students and give personalized feedback.

Areas For Improvement

Grammarly and Turnitin aren’t perfect, and here are some areas I think the founders should focus on improving:

  • Grammarly only works in English
  • Turnitin isn’t accessible to everyone

Grammarly Only Works In English

Grammarly is an impractical option if you create content in multiple languages because it only works in English. But Grammarly is still a relatively new tool, and I’m sure it’ll introduce grammar checking features for other languages in the future. Opt for Microsoft Editor if you need a tool that works in most languages.

Turnitin Isn’t Accessible To Everyone

To use Turnitin, you have to be a student or lecturer at a university since it requires an ID number when signing up. But you can still access the Turnitin plagiarism scanning engine by using Scribbr as Turnitin powers it and offers the same accuracy.

Pros Of Grammarly
  • Regularly updated
  • Best-in-class accurate grammar checker available
  • AI-powered assistant rewrites sentences so they’re easier to understand
  • Automatically saves your work
  • Free version better than basic grammar checkers
Cons of Grammarly
  • Only supports English
  • Premium version costs $30 per month, which is pricey for students
  • Plagiarism checker not as comprehensive and TurnItIn for academics
Pros Of Turnitin
  • Teachers can use the bulk checker to scan up to 15 documents at once
  • The dashboard promotes collaboration amongst teachers and students
  • You can compare offline work to see if students are copying from each other
  • Turnitin has one of the most accurate scanners available
Cons Of Turnitin
  • Not available outside of academia, unless you use Scribbr
  • No grammar and spell checking options
  • Less suitable for checking blog posts, emails, articles etc.

Our Testing Criteria

When reviewing and testing Grammarly and Turnitin, I used these criteria to see if they are worth it and who’ll benefit from them:

  • Ease of use 
  • Accuracy
  • Affordability
  • Additional features
  • Accessibility 

After using Grammarly for over four years and testing the Turnitin engine by scanning multiple articles, I feel both tools meet these criteria; however, it depends on who you are and your writing needs.

For example, if you’re a student looking for the most accurate plagiarism checker, Turnitin is better due to the more extensive database. If you’re a freelance writer who wants to improve and needs the best writing assistant and a decent plagiarism checker, Grammarly is for you.

Where I feel Turnitin falls short is in the accessibility department. If you want to use Turnitin, your university must contact Turnitin and work a deal out with them. You can’t just sign up for a plan, but you can use the Scribbr plagiarism checker powdered by Turnitin to get a feel for the accuracy.

Why Trust Us?

I’ve pasted hundreds of articles into Grammarly and Turnitin engines like Scribbr and Enago, which took my content to the next level.

I found Grammarly’s artificial intelligence reliable, and I always paste articles into the desktop app before starting my first rounds of edits. Although the plagiarism checker isn’t as accurate as Turnitin, overall, I found it’s a more helpful tool. I won’t use Turnitin-powered tools going forward since it’s quite costly. Copyscape has similar accuracy for a fraction of the price.

Final Thoughts: Grammarly Vs Turnitin

Which tool is best depends entirely on your needs and profession. If you’re a copywriter, blogger, or journalist looking to create better writing while checking your work for duplicate content, Grammarly is for you. It’s the most accurate writing assistant available, and even though the plagiarism checker doesn’t have Turnitin’s accuracy, it gets the job done.

Turnitin is a better option if you’re a student, teacher, or anyone working in academia. The AI assistant grading allows teachers to streamline the grading process. As a student, you can work on and submit assignments digitally and check for originality with 100 percent accuracy.
