Review workflow
A quick text comparison tool for spotting meaningful changes without noise.
The Text Diff Checker helps with the everyday comparison work that happens outside a full repository: copied config, generated output, SQL snippets, documentation changes, email drafts, JSON samples, and small pieces of code pasted from different places.
A good diff makes review calmer. Instead of rereading both versions from scratch, you can focus on what changed and decide whether the difference is intentional. That is especially useful when formatting, line endings, or repeated boilerplate make two chunks of text feel more different than they really are.
This is a lightweight comparison tool, not a replacement for source control. For project files, use Git history and proper code review. For private data, sanitize samples before pasting them into any public browser utility.
