How does the paraphraser work?
▼
It uses a built-in thesaurus of common English words with mode-specific synonyms. For each word in your text, it checks the thesaurus and replaces it with an appropriate synonym while preserving capitalization and punctuation.
What are the different paraphrase modes?
▼
Formal mode uses professional language, Casual mode uses everyday conversational words, Academic mode uses scholarly vocabulary, and Simple mode uses basic easy-to-understand words.
Is my text sent to a server?
▼
No. All paraphrasing happens entirely in your browser using a bundled thesaurus. Your text never leaves your device.
Why are some words not changed?
▼
The thesaurus covers approximately 500 common English words. Proper nouns, technical terms, and less common words are kept unchanged to preserve meaning.
