There are a number of plagiarism checking tools available on the market. Here I compile the some of the free plagiarism checking tools, as well as paid plagiarism checking tools. I mention some of the best alternatives to Turnitin (most used plagiarism checker at universities).
List of Best Plagiarism Checking Tools or Software
No doubt, Grammarly is the best plagiarism checking, as well as grammar checking software. The best thing about Grammarly is that we can check plagiarism while writing, instead of uploading a file after completing the task of writing. So Grammarly saves time. Grammarly is useful for academic purposes as well as for writing unique SEO content for websites as well. We can say that Grammarly is the best plagiarism checking tool and best alternative to Turnitin.
Grammarly uses Google API to find similar strings indexed by Google. Grammarly also has its own database, which includes a large number of publications. Most of the plagiarism checkers only use the Google API to check plagiarism, which is why the plagiarism report generated through another plagiarism checker always shows a lower percentage than that of Grammarly.
Copyscape is also a popular plagiarism checker tool. However, it is not as popular as that of Grammarly. Copyscape is widely used to check websites for copied content. To review any document, we have to upload a file, as with Turnitin. The similarity reports generated by Copyscape are thoroughly detailed and include the sources of the plagiarised content
According to ProwritingAid, their tool is the best alternative to Turnitin. Yes, it is a powerful tool to check plagiarism. It works the same way as Grammarly does. However, Grammarly is much better than prowritingAid due to its easy to use interface. I experienced some programming errors and loading issues while using prowritingAid. However, it is much better than any other software on the list.
4. Plagiarism Checker X
Only the desktop version of the Plagiarism Checker X is available right now. This is also one of the most used plagiarism checkers. A free trial of Plagiarism Checker x is possible. But there are some limitations on the free trial.
In the free trial, a check for similarity is limited to the indexed resources. To find all of the possible plagiarism in a manuscript, you have to upgrade to their paid version. With this, I would recommend going for either Grammarly or ProwritingAid, due to their greater variety of features, as well as ease of use with any software or browser like Chrome and Safari.
Write Check is the plagiarism checking tool develop by Turnitin; there is no doubt about their plagiarism checking ability. However, this tool will cost you more than any of the plagiarism checkers listed above.
So, in the List of the Best Plagiarism Checking Tools, overall Grammarly is the best tool to check plagiarism, and additionally has other useful features.
