Frequently Asked Questions
How does the similarity percentage work?
The similarity percentage is calculated using multiple algorithms: word overlap (30%), 3-gram phrase matching (40%), and 5-gram phrase matching (30%). This combined approach provides accurate detection of both word-level and phrase-level similarities.
What do the similarity levels mean?
Very Low (0-20%) means texts are quite different. Low (20-40%) shows some overlap that could be coincidental. Moderate (40-60%) suggests shared sources. High (60-80%) indicates derived content. Very High (80-100%) suggests direct copying.
Can this tool search the web for plagiarism?
No, this tool only compares two texts that you provide. It doesn't search the internet or any databases. For web-based plagiarism checking, you would need a service with web crawling capabilities.
Can it detect paraphrased content?
This tool is designed to detect direct copying and exact phrase matches. Heavily paraphrased content with different wording may not be detected as similar, even if the ideas are the same.
Is my text kept private?
Yes, all processing happens entirely in your browser using JavaScript. Your texts are never uploaded to any server, ensuring complete privacy and confidentiality.
