Frequently Asked Questions
What's the difference between diff views?
Side-by-side shows old and new text in parallel. Inline shows changes within the text flow. Unified diff uses the standard format from version control tools.
Can I ignore whitespace changes?
Yes! Enable whitespace ignore to focus on meaningful content changes. This is helpful when formatting changed but content didn't.
How do I compare large texts?
The tool handles large texts efficiently. For very long documents, the summary shows changed line counts. Scroll through the diff to see all changes.
