About this tool

Compare two texts side by side and see every difference highlighted. Our Text Diff Checker supports two view modes: inline (unified diff with +/- markers) and side-by-side (split view with line numbers on both sides). Additions are highlighted in green, deletions in red, and modifications in yellow. Options include ignore case (treat uppercase and lowercase as identical) and ignore whitespace (ignore spaces, tabs, and indentation changes). The tool shows diff statistics: number of lines added, removed, modified, and unchanged. Load a sample to see the diff in action. Essential for code review, comparing configuration files, checking document revisions, and verifying text changes before deployment.
