Frequently asked questions
- How does line-level diff work?
- Line-level diff compares your two texts line by line. Entire lines that were added or removed are highlighted, making it easy to see which paragraphs, sentences, or code lines changed.
- When should I use line diff instead of word diff?
- Line diff is best for documents where you want to see which entire lines changed, such as configuration files, lists, or structured text. Word diff is better for editing and proofreading where you need word-level precision.
- Can I ignore whitespace-only changes?
- Yes. Toggle the Ignore Whitespace option to skip lines that only differ in spacing or indentation. This is useful for code and formatted text where whitespace changes are not meaningful.
