How the Text Diff Tool Works

Our text diff tool uses a word-level comparison algorithm to identify differences between two pieces of text. Additions appear in green, deletions in red with strikethrough, making it easy to spot changes at a glance.

Perfect for Code Review

Compare code snippets, configuration files, or any text documents. The monospace font ensures proper alignment, and the color-coded output makes reviewing changes quick and intuitive.

Privacy Guaranteed

All comparison happens locally in your browser. Your text is never uploaded to any server, making this tool safe for comparing sensitive documents, code, or personal content.
