How does the visual diff checker work?

The diff engine compares two blocks of text (Original vs. Modified) using the Myers diff algorithm. Added text is highlighted in green with plus markers, and removed text is highlighted in red with minus markers.

Is my text data saved or sent to any server?

No. All text manipulations and comparisons run exclusively in your browser memory. No text is ever uploaded or logged.

Text Suite & Diff Checker FAQ

What is the difference between camelCase and PascalCase?

In camelCase, the first word is lowercase while subsequent words start with a capital letter (e.g. everydayUsedApps). In PascalCase, every word begins with a capital letter (e.g. EverydayUsedApps).

Can I use this tool to compare legal contracts or software code?

Yes! The visual diff tool highlights added and removed lines and words with precise markers, making it ideal for checking NDA clauses, legal amendments, JSON configurations, or programming source code.
