Frequently Asked Questions
Does this tool compare word-by-word or line-by-line?
This tool compares line by line. If a single word changes within a long line, the entire line will be marked as changed.
Can I compare code with this tool?
Yes, it works on any plain text including source code, though a dedicated code-diff tool may give more granular (character-level) results.
