Frequently Asked Questions
What's the difference between character, word, and line comparison?
Character comparison shows every character difference (most detailed), word comparison shows word-level changes (standard), and line comparison shows line-by-line differences (fastest).
What does the similarity percentage mean?
Similarity shows what percentage of the text remained unchanged. 100% means texts are identical, 0% means completely different.
Can I use this to check for plagiarism?
This tool shows differences between two texts you provide. It's useful for comparing versions of your own work, but not for plagiarism detection.
Is there a text length limit?
No, you can compare texts of any length. Very long texts may take a few seconds to process.
