What comparison modes are available?

Line mode compares text line-by-line (best for code). Word mode compares individual words (best for prose). Character mode compares every character (best for finding typos).

What do the colors mean?

Green (added) shows content present only in the modified text. Red (removed) shows content present only in the original. Unchanged content has no highlight.

Does ignoring whitespace affect the result?

Yes. When enabled, differences in spacing, tabs, and indentation are not counted as changes. Useful for comparing code with different formatting.

Is there a size limit?

The comparison runs entirely in your browser. Very large texts (>100,000 lines) may be slow depending on your device.
