Good to know
The comparison uses the "diff" library (BSD licence), which finds the smallest set of changes between the two texts. Lines mode is best for code and lists, Words mode for letters and essays, and Characters mode for short strings such as IDs or spellings.
"Ignore case" treats Pune and pune as the same; "Ignore spaces" skips differences that are only spaces or indentation. The counters show how many lines, words or characters were added and removed.
Copy result gives the differences as text: in Lines mode each line starts with + (added), - (removed) or a space (same), the format developers know from patches; in Words mode removed parts appear as [-…-] and added parts as {+…+}. Very large texts may take a few seconds.
