What is Paraphraser.io?
Paraphraser.io is an online AI paraphrasing tool. It rewrites sentences, paragraphs and articles and tries to keep the original meaning. It also works as a word changer, offers synonym suggestions, and has a frozen-words option so key terms stay as they are.
You paste text, upload a file, pull text from an image or screenshot, or use speech-to-text input. Then you pick a mode, such as Fluency, Formal, Creative, Academic, Shorten, Expand, Humanize or Custom. To swap a synonym, click a word in the output. The tool supports more than 20 languages, and the same site offers a plagiarism checker, grammar checker, summarizer and AI humanizer.
The free tier gives access to five basic modes, with a per-request word limit. Paid plans can be bought by the week, month or year, and they raise the limits and unlock more modes. API access is included only on the annual Diamond plan. The tool fits students, writers and anyone who needs text reworded quickly in a browser.
