  • To Help Write Independently

You are not the only one in the world who can write code. Therefore, when you use other people’s code, you have to ensure that it is not plagiarized or copied from somewhere else. This is where the plagiarism checker comes into play. It will help you write independently and avoid any kind of issues in the future.

  • They Give Comprehensive Reports

You will receive a comprehensive report once you upload your file to the tool. The report will include all the similarities found within the document, their source links, and locations on the internet. This way, you can easily find out if any of them is plagiarized or not so that you know how to proceed further with your work without any problems whatsoever!
