Paraphraser.io is a web-based AI paraphrasing tool that rewrites sentences, paragraphs, and full articles while preserving their original meaning. The platform offers more than ten rewriting modes, including Word Changer, Fluency, Standard, Formal, Smooth, Creative, Humanize, Smarter, Shorten, Academic, and Expand, along with a customizable mode. Users can click individual words to swap in context-aware synonyms, freeze specific terms so they are not reworded, upload documents, dictate text via speech-to-text, and extract text from images or screenshots for paraphrasing.
The tool is built on natural language processing algorithms designed to keep the original meaning intact while improving readability and vocabulary. It supports more than 20 languages, including English, Spanish, French, German, Portuguese, Russian, Japanese, and Chinese. The site also bundles companion writing utilities such as a plagiarism checker, grammar checker, text summarizer, AI essay writer, and AI humanizer.
Paraphraser.io is aimed at students, bloggers, marketers, and webmasters who need to reword existing text to avoid plagiarism or improve clarity. It is accessible from any browser, offers mobile support for Android and iOS, and provides an API that is marketed to colleges and universities. A free tier allows paraphrasing up to 400 words at a time with basic modes; paid plans (weekly, monthly, and annual billing) raise word limits and unlock all modes. The company operating the site lists an address in London, United Kingdom.
