Learn how to find differences between two text documents, code files, or legal agreements. Compare split side-by-side or unified diffs, copy git patches, and export PDF audits.
Whenever developers review pull requests, writers revise draft articles, or lawyers audit legal contracts, finding exact differences between two versions of text is critical. Manually scanning thousands of words is slow and error-prone.
A **Diff Checker** computes the longest common subsequence (LCS) between two text streams and highlights added, modified, and deleted lines with color coding.
