Frequently Asked Questions
Does it compare line-by-line or character-by-character?
It performs line-based comparison, similar to standard code diff tools, highlighting which whole lines were added, removed, or changed.
Can I use this to compare two versions of code?
Yes - it works on any plain text, including source code, making it useful for reviewing changes between two versions of a file.
Is whitespace-only difference (like indentation) highlighted?
Yes, since indentation changes affect the line's exact content, they'll show up as a difference - trim or normalize whitespace first if you only care about content changes.
