About Text Diff Checker

Our Mission

We believe that comparing texts should be simple, fast, and secure. That's why we created Text Diff Checker - a free, open-source tool that runs entirely in your browser without requiring any server-side processing or data uploads.

Our Story

Text Diff Checker was born from the need for a simple, reliable way to compare texts without worrying about data privacy or registration requirements. We noticed that most online diff tools either stored user data or required sign-ups, so we decided to create something better.

Our Values

• Privacy First - Your data is yours alone, never stored or transmitted
• Simplicity - No unnecessary features, just what you need
• Accessibility - Free for everyone, no registration required
• Performance - Lightning-fast comparison using optimized algorithms
• Open Source - Transparent and auditable code
• Continuous Improvement - Regular updates and new features

Technology

Text Diff Checker uses the Longest Common Subsequence (LCS) algorithm to compute differences between texts. All processing happens in your browser using JavaScript, which means:

• ✓ Zero server costs = no ads needed
• ✓ Instant results = no network latency
• ✓ Complete privacy = no data collection
• ✓ Works offline = no internet required

The Team

Text Diff Checker is built and maintained by a small team of developers who are passionate about creating useful tools. We work in our spare time to keep this service free and ad-free for everyone.
