Frequently Asked Questions

How accurate is the similarity scoring?

Our tool uses the Longest Common Subsequence (LCS) algorithm to calculate similarity scores. This provides accurate measurements of how similar two texts are based on their common elements.

What's the difference between comparing by lines, words, and characters?

Line comparison is best for code or structured text, word comparison works well for documents and articles, while character comparison provides the most granular analysis for detailed text changes.

Can I ignore certain elements during comparison?

Yes! You can choose to ignore case sensitivity, whitespace, and punctuation to focus on the actual content differences that matter most to your use case.

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

The tool can handle large texts, but performance may vary based on your device's capabilities. For very large documents, consider breaking them into smaller sections for optimal performance.

How does the real-time comparison work?

The tool uses intelligent debouncing to analyze your text as you type, providing instant feedback without overwhelming your browser with constant calculations.

Is my text data secure?

Absolutely! All text comparison happens entirely in your browser. Your text is never uploaded to our servers or stored anywhere.
