Rewording someone else’s ideas without crediting them is still plagiarism, whatever the wording. Paraphrasing changes expression, not authorship — you must cite the source either way. Where it is genuinely useful is rewriting your own drafts: tightening clumsy sentences, shifting register, or fitting a piece to a different audience.
Formal suits reports, applications and anything client-facing; it removes contractions and colloquialisms. Casual loosens the register for blogs, newsletters and social posts. Creative takes the most liberty with phrasing and metaphor, which is good for marketing copy but worth reading closely, since it strays furthest from your original meaning.
Usually, but always reread the output. Paraphrasing is a rewrite rather than a substitution, so nuance can shift — hedged statements can become assertive, technical terms can be swapped for looser synonyms. Check anything precise: numbers, names, conditional wording and domain-specific vocabulary where the exact term matters.
