FAQ

How does the text compare tool work?

It compares the two texts line by line using a longest-common-subsequence diff, then marks each line as unchanged, removed, or added.

What do the - and + symbols mean?

A line starting with "-" exists only in the original text, and a line starting with "+" exists only in the second text. Unchanged lines have no symbol.

Does it compare word by word?

The comparison is line by line, which works well for lists, paragraphs, and code. Put each item on its own line for the clearest results.
