What is Turnitin?

Turnitin also is one of the great software developed back in 1997. The software was developed primarily to detect copied content in your document. This American Internet-based website identifies the duplicity sentences and alerts you with a certain mark in the plagiarised sentences.

Main Differences Between Grammarly and Turnitin

  1. Grammarly does provide some of its services for free whereas Turnitin does not provide any kind of free services. This strategy helped Grammarly penetrate the Indian market.
  2. Grammarly provides a free grammar checker whereas Turnitin does provide but you need to contact your account administrator to enable the grammar checker for the account which becomes irritating.
  3. Both Grammarly and Turnitin have a large database. Turnitin’s database of its students will make sure that no one gets away with plagiarism. Grammarly’s plagiarism database is quite extensive too.
  4. Grammarly Plagiarism checker scans sentences which means that if you change one word from that sentence then you might get rid of the plagiarism in that particular sentence, but, Turnitin scans every word, letter, symbol. So you just cannot change a word from a sentence because it will still be marked as plagiarised.
  5. The reliability score is much better of Turnitin than Grammarly but it lacks the extra features that Grammarly provides to its users.


No doubt that both these applications are best in their way and have got some standout features. But, it all depends upon the uses of the users. Say suppose if you want to conduct in-depth plagiarism checks then Turnitive must be the first choice for you.

Grammarly Pro on the other hand becomes very useful for content marketers that need an online tool to improve their content and conduct their plagiarism checks from time to time.

If you have an important document to submit and you need to make sure that your document is free of grammar errors then I suggest you use the paid version of Grammarly.

However, Grammarly is slightly ahead of Turnitin because it is the best tool for individuals and user-friendly too. You can get your own experience and find it out on your own by checking the free version of Grammarly.

Grammarly is most recommended when an individual wants to improve their writing skills whereas Turnitin does not have this service.

However, there are plenty of other options available on the internet for free. Some of them are Plagiarisma, Viper, Quetext, Small seo tools, Edubirdid, and many others. But, the question arises is do you trust these free websites, and can these guarantee you the best plagiarism checker?
