What this text diff is for

Use this tool when you need to compare two versions of copy, code, notes, or configuration before you merge, publish, or send anything out.

How to read the result

The side-by-side view helps you scan line numbers and changed fragments quickly. Switch to the unified view when you need a compact patch-style output for review, handoff, or documentation.

When the options matter

Ignore case when capitalization is noise. Ignore whitespace when indentation or spacing should not count as a real edit. Hide unchanged rows when you only want to inspect what actually moved.
