What is a diff algorithm and how does it work?

A diff (short for "difference") tool compares two versions of a text and outputs the minimum set of changes — additions, deletions and unchanged sections — needed to transform one into the other. Our implementation uses the Longest Common Subsequence (LCS) algorithm, the same mathematical foundation used by Unix diff, Git's version control system and Google Docs' revision history. The LCS algorithm finds the longest sequence of lines that appear in both texts in the same order, then identifies everything else as either added or removed. The result is a precise, character-accurate change map that makes even subtle edits immediately visible.

When is text comparison most valuable?

Software development: reviewing code changes before merging (pull request review). Legal: comparing contract drafts to identify changes between versions — every modified clause must be noticed. Academic: plagiarism detection, comparing submitted essays against source material. Journalism: tracking changes in official documents, press releases or statements over time. Translation: ensuring translated versions remain aligned with updated source text. Content management: comparing page copy before and after an update. Pair with our Word Counter to assess the volume of each text version before comparing.
