Compare two texts and see added / removed lines.
Paste two versions of text and see a line-by-line comparison: lines prefixed with - were removed, + were added, and unchanged lines are shown for context. Useful for comparing config files, copy revisions or code snippets. Runs entirely in your browser.
Line-based — it compares whole lines using a longest-common-subsequence algorithm, like a simplified git diff.
Yes — the comparison happens locally in your browser; nothing is uploaded.
