Frequently Asked Questions

How do I format the input for comparison?
Use ===LEFT=== to mark the original text and ===RIGHT=== to mark the modified text. Each section should be on a new line.
What diff modes are available?
You can compare by lines (default), words, or individual characters. Line mode is best for code and documents, word mode for content changes, and character mode for precise edits.
Can I ignore whitespace differences?
Yes, enable "Ignore Whitespace" to focus on content changes rather than formatting differences.
What do the symbols mean?
+ indicates added content, - indicates removed content, and unchanged lines are shown with context when enabled.
How accurate is the diff algorithm?
We use the Longest Common Subsequence (LCS) algorithm, which is the same method used by professional diff tools like Git.
