The tool ships with a built-in library of hundreds of English synonym pairs covering adjectives, verbs, nouns, and adverbs. When you click Paraphrase, the tool scans your text word by word, looks up each token in the synonym library, and randomly selects a replacement when a match is found. Everything happens locally — no API calls, no data leaving your browser.
The tool is built around word-level synonym substitution, so it increases vocabulary variety without changing sentence structure or logic. We recommend treating the output as a draft and polishing it manually. You can fine-tune the rewrite by toggling which parts of speech to replace.
No. The entire pipeline runs locally in your browser. Your text is never sent to or stored on any server, so it is safe to use with sensitive or private content.
