Frequently asked questions

Simple answers to your questions

Is a plagiarism detector the same as a grammar checker?
No. A grammar checker focuses on spelling, punctuation, readability and writing mechanics. A plagiarism detector focuses on text similarity and potential matches with existing sources.
Can I check plagiarism after editing grammar?
Yes. It is often helpful to run a plagiarism check before and after major editing, because revised wording can change similarity results and reveal passages that still need attribution.
Why should I use plagiarism detection with a writing tool?
Grammar and style improvements do not verify originality. Combining editing with similarity review can help you produce writing that is both polished and appropriately sourced.
What should I review after a plagiarism scan?
Review each highlighted match, the linked or identified source, the percentage of overlapping text and whether the passage has proper quotation or citation treatment.
