Compare two texts and see added, removed, and unchanged lines.
Compare two versions of text, code, configuration, or notes with a readable line-based diff. Added and removed lines are marked in the result, while an optional whitespace setting helps you focus on meaningful line changes. The comparison is a local structural comparison, not semantic code analysis, and it never executes the text you paste.
