Shelf feature
Rewrite in your words. Check against your library.
Paraphrase a highlight or Doc passage with Tutor. Originality reports library and syllabus overlap — and Premium web scans when a plagiarism vendor key is configured.
What you get
- Paraphrase, Simplify, Formal, and Shorten from the selection bar
- Insert paraphrases back into typed Docs
- Library self-check via the same vector index as Tutor
- Course-outline overlap to check topical relevance
- Optional AI-writing heuristic (token-metered, labeled as a hint)
- Premium web originality through Copyleaks when API keys are set
Shelf’s originality tools help you spot reused personal notes and syllabus phrasing while you write — not a fake Turnitin clone. Free and Premium include library and syllabus layers; public-web scanning stays Premium and only runs when a vendor is connected.
Use paraphrase to study in your own words. Use originality before you submit a draft to catch accidental copy-paste from your own uploads.
