Tool guide
Compare two text versions line by line
Compare text side by side or in a unified view, showing added, removed and unchanged content.
How to use
- Paste the old and new versions.
- Choose a view and review changes with line numbers.
Example and expected result
Left: name=old
Right: name=new
Expected: the old line is removed and the new line is added.Capabilities and limits
- Comparison is line-based, without semantic analysis or automatic conflict merging.
- Formatting-only changes can produce many differences.
Troubleshooting
Normalize line endings and formatting when differences are noisy. Swapping sides reverses the meaning of additions and deletions.
Data processing and storage
Text is compared in page state without reading a Git repository or automatically saving input.
