How to paraphrase without plagiarizing
Paraphrasing done right shows you understood a source well enough to say it your own way. Done wrong, it's plagiarism with a thesaurus. The difference comes down to a few clear rules.
What counts as real paraphrasing
A genuine paraphrase changes both the words and the sentence structure while keeping the meaning — and still credits the source. Swapping every third word for a synonym while keeping the original's skeleton is called patchwriting, and plagiarism checkers (and professors) catch it easily.
A process that works
1. Read the passage until you can explain it without looking.
2. Write your version from memory, in your own voice.
3. Compare against the original: different structure? No copied phrases of more than a few words?
4. Cite the source. Paraphrasing changes the words, not the debt.
Where an AI paraphraser fits
A paraphrasing tool is excellent at step two: it restructures sentences and reworks vocabulary in seconds, in the register you pick — formal, simple, shorter, longer. Treat its output as a draft: verify it kept your meaning, adjust anything that sounds unlike you, and keep the citation.
The mistakes that get flagged
Keeping the source's sentence order with swapped words; unique multi-word phrases carried over verbatim; paraphrasing so aggressively the meaning drifts; and forgetting the citation entirely. Any one of these can sink otherwise honest work.
