Find Quick Answers

How does the similarity percentage calculation work?

The tool uses advanced algorithms to compare texts at the selected level (character, word, or line). It calculates the percentage based on matching elements divided by total elements, providing an accurate similarity score.

Can I compare large documents with this tool?

Yes, the tool can handle substantial text content. However, for optimal performance, we recommend comparing texts under 10,000 characters each for the best user experience.

What's the difference between character-level, word-level, and line-level comparison?

Character-level compares individual characters, word-level compares complete words (ignoring whitespace differences), and line-level compares entire lines of text. Choose based on your specific comparison needs.

Yes, all text comparison happens entirely in your browser. No data is sent to any server, ensuring complete privacy and security for your content.
