Precise about what
a check can tell you.
We check discoverable public sources. We do not have a private student-paper repository or proprietary journal database. Search coverage and source access affect the result.
Quoted passages and references can be excluded. Shared phrases are counted once even when several sources repeat them. Semantic paraphrase detection is not enabled.
Your text is stored privately for up to 30 days and can be deleted earlier. Selected phrases are sent to Serper for discovery.
