FAQ

Is this a full code diff engine?

This version focuses on practical line-by-line comparison for general text, not advanced source-control diff behavior.

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

The tool is designed to process ordinary input in your browser. Avoid pasting passwords, private keys, access tokens, personal records, or other sensitive production data into any online utility.

Limitations

This utility handles the focused workflow described on this page. Check the result before production use, especially when an input depends on a vendor-specific format, security rule, or external standard.
