Compare two blocks of text and see exactly what changed.
Line by line, using a longest-common-subsequence algorithm — the same underlying approach as git diff — so unchanged lines are matched even when other lines around them changed.
Yes, by default — a trailing space makes a line count as different. Turn on "ignore leading/trailing whitespace" if you only care about content changes.
Yes — the comparison is line-based and works for any plain-text content, including source code, config files, or CSV data.
No, differences are shown at the line level — an entire line is marked added or removed, not individual words within it.
