Text Diff Tool

Whether you're a developer reviewing code changes, an editor comparing document drafts, a teacher checking for plagiarism, or a writer tracking revisions, our Text Diff Tool provides clear visual comparison of two text versions. Added text is highlighted in green, removed text in red strikethrough, unchanged text remains normal. The tool identifies additions (text in new version not in old), removals (text in old version not in new), and changes (shown as removal + addition). Three comparison algorithms: Line-level diff (compares entire lines, best for code, Git diffs, configuration files), Word-level diff (compares within lines, best for prose, essays, legal clauses), Character-level diff (fine-grained, best for typos and minor edits). Diff algorithms include Myers Diff (fastest, used by Git), Patience Diff (better for complex code indentation), and Histogram Diff (most accurate for repeated lines). Use cases: code review, version control commit comparison, debugging, merge conflict resolution, document revision tracking, legal contract redlines, plagiarism checking, peer review, log file analysis, API response comparison, and CSV/JSON data comparison.

Text Diff Tool is optimized for fast browser-based use, so you can test multiple scenarios in seconds.
