First distinguish your own words and ideas from quotations, paraphrases, and borrowed facts. Add citations where needed, mark direct quotations clearly, and rewrite paraphrases that follow the source too closely. Remove copied research notes that were never meant for the final draft.
Then use a plagiarism checker as a prompt for manual review, not a verdict. A match may be a properly cited quote or common phrase; an unflagged sentence may still misuse someone else's idea. Check each highlighted passage against the source and your institution's or publisher's rules.
Do not upload confidential or unpublished material to any checker without reviewing its data policy.
