Frequently Asked Questions
What is a text diff?
A text diff (short for difference) is a comparison between two texts that highlights what has been added, removed, or changed. It is commonly used in version control systems (like Git), code review, and document comparison.
What is the difference between Line Diff and Word Diff?
Line Diff compares text line by line and works best for code and structured documents. Word Diff compares text word by word and is better for prose, paragraphs, and sentences where changes might be within a line.
