About Text Diff
Compare two blocks of text instantly and highlight inserted, deleted, and unchanged lines. The comparison runs locally in your browser, so private text, code, notes, and configuration files are not uploaded to a server.
Common Uses
- Review document revisions before publishing.
- Compare code snippets, prompts, logs, or config files.
- Check translated text against a source draft.
- Find small edits in large copied text blocks.
FAQ
Is my text uploaded to MKDiff?
No. The diff calculation runs in your browser, so the text you paste stays on your device.
Can I compare code with this tool?
Yes. You can paste code, config files, logs, Markdown, or any plain text and compare the differences line by line.
What do the colors mean?
Green highlights added content, red highlights deleted content, and unchanged lines remain neutral.
Does Text Diff work on mobile?
Yes. The page is responsive, although large files are easier to review on a desktop screen.
