Frequently asked questions
Is my text uploaded?
No. Diffing runs entirely in your browser—useful for drafts, configs, or snippets you would rather not send to a remote service.
Is this a full Git-style diff?
It is a practical line-by-line comparison with a short look-ahead for reordered blocks—not a full Myers/Git patch engine. Ideal for quick checks, not patch generation.
What does the summary mean?
The summary counts lines marked added vs removed so you can see the size of the change before reading every highlight.
