How to Compare Text
A "diff" (short for difference) tool is used to compare two files or blocks of text and highlight the changes between them. This is incredibly useful for developers reviewing code changes, writers tracking revisions in a document, or anyone needing to spot what has been altered between two versions of a text. Our tool provides a simple, clear, line-by-line comparison to make this process easy.
