FAQ
Is this a full code diff engine?

Can I compare article drafts with it?
Yes. It works well for pasted drafts, templates, prompts, and other text-heavy workflows.
How it works
A simple browser-based diff checker for content revisions, copied snippets, and change reviews. The result is produced immediately so you can review it before copying or using it elsewhere.
Privacy
