Frequently Asked Questions

How does the text difference checker work?

The tool compares two blocks of text and identifies the differences by analyzing them either word by word or character by character. It highlights additions, removals, and unchanged segments based on your selected settings.

Can I ignore case and whitespace differences?

Yes, you can enable the "Ignore case" and "Ignore whitespace" options to focus solely on meaningful content changes, disregarding case sensitivity and extra spaces.

What is the difference between unified and split views?

The unified view displays both texts in a single column with differences highlighted inline, while the split view presents the original and modified texts side by side for easier comparison.

Is there a limit to the text size I can compare?

The tool can handle large blocks of text efficiently. However, extremely long texts may take slightly longer to process. It's recommended to use the tool for documents up to several thousand words for optimal performance.
