Home / Tools / Does paraphrasing avoid plagiarism?
No. Paraphrasing changes the words, not the ownership of the idea. A paraphrase without a citation is plagiarism in most university policies, even when every sentence is new. Cite the source, keep the technical terms exact, and use a paraphrase to show you understood the passage, not to hide it.

Plagiarism is using someone else's work without attribution. Rewording changes the words in the sentence and leaves the work in place. The attribution is still missing.
Most university policies treat an uncited paraphrase as plagiarism of the same kind as a copied sentence, and many treat it more harshly because it is harder to spot by eye.
A citation in the style your course uses, with the page or paragraph number when the idea sits in one place.
A signal phrase that shows whose idea it is: according to, as reported by, building on.
The technical terms unchanged. Replacing a defined term with a looser word makes the paraphrase inaccurate as well as unattributed.
A clear boundary between the source's claim and your comment on it. If a reader cannot tell where the source stops, the paraphrase fails even with a citation.
A similarity checker compares your text with a collection of documents and reports the share of matching wording. It reports matches, not intent. A quoted block with quotation marks and a citation will still show as a match.
A low similarity score is not proof of good practice. A paraphrase that swaps every third word can score low and still copy the structure and the argument of the source.
Treat the score as a list of places to look. Open each highlighted passage and ask whether the claim is attributed, not whether the words differ.
Reusing your own earlier essay without saying so is treated as plagiarism by many institutions. The words are yours, the credit for the assignment is not.
Check the course policy before you reuse a paragraph from your own previous work. A citation to your own earlier paper is usually the accepted fix.
Every paraphrased idea has a citation.
Every quoted phrase keeps its quotation marks.
Every technical term matches the source.
Your own comment is visibly separate from the source's claim.
The reference list entry matches the in-text citation.
The plagiarism risk checker finds overused phrases and clichés that often look unoriginal. It does not search a database of sources and it does not know your citation practice.
Use it to find flat, borrowed-sounding wording, then fix the citation yourself. A clean score is not a licence to leave a source unnamed.
