Text Diff gives one continuous diff output (like a patch), defaults to line-by-line comparison, and lets you hide unchanged text—ideal for configs and code-shaped text. Text Compare is built for editorial review: side-by-side or inline layout, explicit modified (old→new) highlights, and download of a written report.
Paste your first text in the 'Text 1' field and your second text in the 'Text 2' field. The tool automatically highlights differences. You can choose between line-by-line, word-by-word, or character-by-character comparison modes.
Line mode compares entire lines, word mode compares individual words, and character mode compares each character. Line mode is best for code or documents, word mode for prose, and character mode for precise differences.
