Frequently asked questions
What diff algorithm is used?
▾
A line-by-line diff using the Myers algorithm — the same algorithm used by git. It finds the shortest edit script (minimum insertions and deletions) to transform one text into the other.
What do the colors mean?
▾
Red lines (−) were removed — present in the left/original text but not in the right. Green lines (+) were added — present in the right/new text but not in the left.
Can I compare code files?
▾
Yes. Paste any text content including code. The diff is purely text-based with no language-specific parsing.
