Is Grammarly a reliable plagiarism checker? + Comparison with Turnitin

TL;DR Here’s the short answer to the question ‘is Grammarly a reliable Plagiarism checker?’

Yes. Grammarly’s collaboration with ProQuest (an extensive database) allows users to run scans against both online (web-based) and offline (hard copy) content.  In my opinion, it’s the best option for those that want both plagiarism and content checking capabilities. However, for those looking for a more extensive plagiarism checker, you could try Turnitin.

Grammarly vs Turnitin: Reviewed & Compared

Turnitin Overview

Launched in 1997, Turnitin is an American based firm and aims at providing the educational Institutions with a tool to check for plagiarism.

They have around 30 million-plus students using their tool by 50,000 different institutions. Pretty big huh?

Since the internet and storage were a luxury back then, Turnitin provided the institutes a cheaper and simpler solution to check their students’ works.

It has an extensive collection of offline database which is focused towards all educational related copies.

All previous articles are stored with them ever since.

Turnitin Pricing: How much does it cost?

There is no official price listing that Turnitin provides.

The only option you have is to contact a sales representative and select a package which best suits your requirements.

But from what the institutions have published, the cost of operation does not run cheap.

Turnitin pricing

Do you see how expensive it can get?

This pricing is primarily because Turnitin is checking for plagiarism extensively from websites, as well as their offline database.

This can get very labour-intensive, mainly because they do not have any intelligence working all the jobs.
