How to Check Text Differences
Type or paste the original version on the left input container and the updated text version in the right text container. The checker immediately runs a Longest Common Subsequence (LCS) comparison to determine exact additions and deletions.
You can toggle between Split View (which renders original and modified columns side-by-side) and Inline View (which overlays differences into a single unified stream, complete with line numbers and standard plus/minus notation).
