What is a text diff tool?

A text diff tool compares two texts and highlights the differences between them. It shows what was added, removed, or modified, making it useful for code reviews, document comparisons, and version control.

How do I compare two texts?

Paste your first text in the 'Original Text' field and your second text in the 'Modified Text' field. The tool automatically calculates and displays the differences with color-coded highlights (green for additions, red for deletions).

What comparison modes are available?

Three modes: Line-by-line (compares entire lines), Word-by-word (compares individual words), and Character-by-character (compares each character). Choose the mode that best fits your needs.

Can I ignore whitespace or case differences?

Yes! Enable 'Ignore Whitespace' to treat all whitespace as equivalent, or 'Ignore Case' to treat uppercase and lowercase letters as the same. This is useful when comparing code or formatted text.

What statistics are shown?

The tool displays statistics: number of additions (new content), removals (deleted content), modifications (changed content), and unchanged content. It also shows the total number of operations performed.

Is the text diff tool free?

Yes, completely free! No registration, no limits, no hidden fees. All text comparison happens in your browser - we never see or store your text.
