Frequently Asked Questions

Find Quick Answers

What counts as a match?

A match is any text segment whose similarity to indexed sources exceeds the configured threshold. It includes exact copies and near-duplicates, with the strongest emphasis on longer, contiguous matches and high-confidence paraphrase indicators.

Is the tool free to use?

Yes, a free online tier provides core plagiarism detection features. Paid plans unlock longer documents, batch processing, API access, and priority processing.

Does the tool store submitted content?

Content is processed securely and stored only transiently by default. Persistent storage or result saving requires explicit user opt-in with clear retention settings and deletion options.

Which languages are supported?

The tool supports multiple languages with language-aware tokenization. Performance is strongest for Latin-script languages; non-Latin scripts are supported where tokenization is available.
