Frequently Asked Questions

Find Quick Answers

What sources are scanned?

The tool scans public web pages, academic databases, and user-uploaded documents. Users may narrow scope to web-only or include journals and repositories for comprehensive checks.

How is the similarity score calculated?

It uses tokenization, TF-IDF or embeddings, and n-gram analysis to compute per-source similarity. A final score aggregates these with thresholds and weighting for quotes and paraphrase.

Can I check quotes or citations?

Yes. You can exclude quoted material from scoring and map detected matches to citations. The report highlights potential citation gaps and suggests references.

Is my content stored after checking?

Data handling follows privacy policies and regional laws (GDPR/CPRA). Content may be stored only with user consent for account-based processing; otherwise, it is processed without persistence.
