FAQ
What does the symbol mean?
A green row with a plus sign is a line that was added in the changed version. A red row with a minus sign is a line that was removed from the original.
Which lines are highlighted?
Only lines that are different. Lines present in both versions in the same order are shown unchanged.
Can I compare code?
Yes — it compares any text, line by line, so it works for code, prose, or any multi-line content.
