Text Diff Tool

Compare two pieces of text and see exactly what changed. Additions are highlighted in green, deletions in red. Works with any text — articles, code, configuration files, or prose.

How to Use

  1. Paste original text on the left.
  2. Paste modified text on the right.
  3. View the diff — additions (+) in green, deletions (-) in red, unchanged lines in gray.
  4. Toggle options — ignore whitespace differences or case sensitivity as needed.

Frequently Asked Questions

What's the difference between this and the Diff Checker?+
This Text Diff tool is focused on plain text comparison with a clean, minimal interface. The Diff Checker tool offers syntax-highlighted code comparison with more features. Use Text Diff for articles, prose, and quick comparisons; use Diff Checker for code review.
What does "ignore whitespace" do?+
When enabled, multiple spaces and tabs are collapsed to a single space before comparison. This is useful when comparing text that may have different indentation but the same content.
