About This Tool
### Spot the Difference
Comparing two versions of a document can be a nightmare. Whether you're checking for plagiarism, reviewing code commits, or editing an essay, spotting small changes manually is error-prone.
**Diff Checker** automates this process.
### How It Works
It uses a "Difference Algorithm" to analyze text character-by-character.
* **Green Highlights**: New text added in the second version.
* **Red Strikethroughs**: Text removed from the first version.
* **No Color**: Text that remained identical.
Perfect for Developers, Editors, and Lawyers.

Frequently Asked Questions
Is data sent to server?
No. The comparison happens entirely in your browser using JavaScript. This makes it safe for sensitive legal documents or proprietary code.
