About this tool

In various versions of documents or other files, it is helpful to learn about the differences of both texts. For example this Text Comparison tool detects skipped lines or words and just different words. Additionally the similarity will be displayed in percent. This value bases on the share of same words in both texts and gives information about the uniqueness of the texts. You want to see how this works? Try the diff checker with his advanced algorithm.Please mind that empty lines or white spaces at the beginning or end of a line will be ignored.

A value over 80% indicates a plagiarism with very high probability, a value over 50% at least with high probability. Especially by shifting of paragraphs the value is less accurate. In addition small changes influence the score the more the shorter the texts are.
