About Text Diff Checker
Text Diff Checker compares two blocks of text line by line and highlights what's added, removed, or unchanged. Uses an LCS (longest common subsequence) algorithm — the same approach used by 'git diff'.
Useful for comparing two versions of a document, spotting subtle changes between drafts, reviewing edits before publishing, and quick QA of paste-overs.
