Text and code diff checker

A diff compares two versions of text and marks what was added, removed or changed. It is useful for reviewing edits in source code, configuration and documents.

Paste the original and updated versions to see their differences. The available views present the changes in different layouts so you can inspect either the overall result or individual lines.

When to use it

Compare drafts, code snippets, settings files or copied outputs before replacing the original.
