About Text Diff Checker
The Text Diff Checker helps you compare two versions of text to identify what changed between them. Whether you're reviewing code changes, comparing document versions, or validating API responses, this tool highlights additions, deletions, and unchanged content with color-coded highlighting.
Choose between three comparison modes: character-level for precise diffs, word-level for balanced comparison, or line-level for the clearest view of code changes. The side-by-side view shows both versions simultaneously, while unified view displays a single column with +/- prefixes like traditional diff tools.
Perfect for developers reviewing pull requests, writers comparing document drafts, or anyone needing to spot differences between text. All processing happens in your browser - your text is never sent to any server. Compare webhook payloads from different requests using HooksDash's request inspection feature.
