About This Tool
Text Diff Checker compares two versions of text and highlights every difference between them. Line diff mode shows which lines were added, removed, or unchanged with color-coded backgrounds. Inline diff mode highlights the exact characters that changed within modified lines, making it easy to spot subtle edits like typos. The tool uses a Longest Common Subsequence (LCS) algorithm for accurate results. Perfect for comparing document drafts, configuration files, or any two texts.
