A text diff (difference) shows what changed between two versions of text. Added content is highlighted in green, removed content in red, making it easy to spot changes.

You can compare any two pieces of text - document versions, code changes, configuration files, or any text content. Simply paste the original and modified text to see differences.

How are the differences shown?

Differences are highlighted line by line. Green highlights show added content, red shows removed content, and unchanged lines appear normally. You can switch between unified and side-by-side views.
