📋 Text Compare

Our free Text Compare tool shows differences between two text versions instantly. Paste original and modified text, click Compare, and see additions (green), deletions (red), and unchanged text. Perfect for developers, editors, writers, and anyone tracking changes.

How it works: Enter your original text (Version A) and your modified text (Version B). The algorithm finds the longest common subsequence between both versions. Differences are highlighted: green background = added text, red background = removed text, no highlight = unchanged.

Example: Version A: 'The quick brown fox jumps over the lazy dog.' Version B: 'The quick brown fox leaps over the energetic dog.' Comparison shows: 'jumps' deleted (red), 'leaps' added (green), 'lazy' deleted (red), 'energetic' added (green). Instant visual diff.

Use cases: (1) Code review — compare code changes before commit. (2) Editing — see editorial changes between drafts. (3) Contract review — spot changes in legal documents. (4) Translation — compare original vs translated text. (5) Academic — check student revisions.
