The tool will help to detect the plagiarism, will share proper comment about plagiarized content and also, will tag us in the comment so we can double check it.

Program that is used to detect the plagiarism is very professional, it's a paid version (cost of one scan is 0.01 USD), so it won't detect plagiarism based on two or three similar words in a sentence as some of the free tools do.

You are right though that every plagiarism require verification by the human.
