Browser-side comparison
Both text blocks stay local to the browser while the diff is computed, which is useful for private drafts and internal snippets.
Line-based output
This view compares lines, not words or characters. Small edits inside a single line show up as one removal and one addition instead of an inline highlight.
Great for quick reviews
The output is intentionally lightweight, so it works well for notes, copy drafts, and config changes without requiring a full Git diff workflow.
Export diff
Run a comparison first to enable export.

Text Comparison and Diff Algorithms for Code Review
Key Takeaways
- Diff algorithms identify the minimum set of changes (insertions, deletions, modifications) between two text inputs.
- Side-by-side and unified diff views help developers quickly identify changes during code reviews and configuration audits.
- All text comparison happens entirely in your browser — your documents never leave your device.
Text comparison (diffing) is fundamental to software development, content management, and document review. From Git diffs and code reviews to comparing API responses and configuration files, understanding what changed between two versions of text is a daily task. Modern diff algorithms efficiently compute the minimum edit distance, presenting changes in an intuitive visual format.
The Myers diff algorithm, used by Git, runs in O(ND) time where D is the number of differences — optimal for similar texts.
Algorithm Efficiency
Common Use Cases
Code Review
Compare code versions to review changes before merging, identifying additions, deletions, and modifications across files.
Configuration Audit
Diff configuration files before and after deployment to verify only intended changes were applied to production environments.
API Response Comparison
Compare API responses between environments (staging vs. production) or between code versions to catch unexpected changes.
Content Revision Tracking
Compare document drafts to identify editorial changes, additions, and deletions during content review workflows.
Pro Tips
Use side-by-side view for large files and unified view for small, focused changes.
Trim trailing whitespace and normalize line endings before diffing to avoid noise from invisible formatting differences.
When comparing JSON or XML, format both inputs consistently first to ensure structural differences are not masked by formatting.
For configuration files, sort keys alphabetically before diffing to isolate actual value changes from reordering.
All text comparison is performed entirely in your browser. Your documents, which may contain sensitive code or business content, are never transmitted to any external server.
