Online Text Compare — How It Works

No installation needed — works in any modern browser. This tool compares two blocks of text word-by-word and shows what was added and removed.

How it works

The tool splits both texts into words and finds which words appear in the new text but not the old (additions, shown with +) and which appear in the old but not the new (removals, shown with -).

Example

Original: The quick brown fox.
Changed:  The quick red fox.

- brown
+ red

Summary: +1 added, -1 removed

Where this is used

  • Reviewing edits to an article or document.
  • Spotting changes between two versions of config, copy, or code snippets.
