What is a Text Diff Checker?

A Text Diff Checker is a utility tool that compares two pieces of text and visually highlights the differences between them. The term 'diff' comes from 'difference' and is commonly used in version control systems and text editors. Our tool performs a line-by-line comparison, making it easy to identify what was added, removed, or changed between two versions of any text content.
