What is a Text Compare Tool?

Text compare, also known as diff (short for difference), is a process or tool used to find the differences between two sets of text. This is commonly used in programming and writing to track changes, find errors, or merge changes.

In programming, text compare tools are often used to see what changes have been made to a codebase over time. This is especially useful in version control systems like Git, where you can compare different versions of your code to see exactly what was added, modified, or deleted.

In writing or document editing, text compare can be used to track changes made to a document over time, or to compare two versions of a document to see what changes have been made.

Most text compare tools work by showing the two sets of text side by side, with differences highlighted. Some tools also provide additional features like merging changes, ignoring certain types of differences, or integrating with other software.
