Frequently Asked Questions
How are changes shown?
Green rows are additions, red rows are removals, and neutral rows are unchanged lines. The comparison is line-based.
Why does a large comparison show many changes?
For very large inputs, the tool uses a simplified fallback to avoid excessive memory use. That fallback may mark unchanged lines as removed and added.
Is my input uploaded or stored?
No. This tool processes your input in your browser. SunloopMedia does not receive or store the content you enter here.
