Paraphraser FAQs

Paraphrasing is putting a piece of text into new words without changing the overall meaning. It involves rephrasing sentences or paragraphs, using synonyms, and restructuring the text while still maintaining the core message. You can paraphrase using your own words or with AI writing tools.

Paraphrasing transforms the text into new words without changing the overall length. On the other hand, summarizing condenses the main ideas of a text into a much shorter version.

Academic writers can use Paraphraser to rephrase cited information, expand or shorten their texts, improve the flow and consistency of their writing, simplify complex language, and more.

Our tool can paraphrase any kind of text, making it useful for a variety of projects. Try it with:

  • Sentences
  • Paragraphs
  • Articles or excerpts
  • Many more
