Tips for Effective Paraphrasing

  • Read and understand first — Put the original away and write from memory.
  • Change sentence structure — Rearrange clauses, combine or split sentences.
  • Use synonyms — Replace key words with alternatives (but keep technical terms).
  • Change voice — Switch between active and passive voice.
  • Always cite — Even a perfect paraphrase needs an in-text citation.

Frequently Asked Questions

How different does a paraphrase need to be?
A good paraphrase should use entirely different sentence structure and vocabulary while maintaining the original meaning. Changing only a few words is considered patchwriting and may be flagged as plagiarism.
Do I still need to cite a paraphrased source?
Yes. Even though you are using your own words, the idea still comes from another source and must be cited. Failing to cite a paraphrase is a form of plagiarism.
What is the difference between paraphrasing and summarizing?
Paraphrasing restates a specific passage in your own words at roughly the same length. Summarizing condenses a longer work into a brief overview of the main points.
How does the similarity score work?
The tool compares your paraphrase to the original text word by word and calculates the percentage of matching words and phrases. A lower similarity percentage indicates a more thorough paraphrase.
