Text Diff

Paste the original text on the left and the changed version on the right. A longest-common-subsequence diff marks each line as added, removed, or unchanged, so real changes stand out even when lines move around. Options let you ignore case differences and trailing whitespace.

Common uses

• Spot what changed between two versions of a document
• Compare configuration files without git
• Verify that an edit only touched the lines it should

Limitations

• The diff is line-based — a small edit inside a long line shows as one removed and one added line
