Swap individual words with their synonyms across any text. Adjustable intensity controls what percentage of eligible words get changed.
Word changing is the most surgical paraphrasing operation — replace specific words with synonyms while leaving everything else untouched. It's a bookkeeping operation: take this set of synonyms and apply them probabilistically across the text.
Paste your text. Pick intensity. Click Rewrite. The tool walks through each word, checks if it has a thesaurus entry, and replaces it with a random synonym at the chosen probability. Punctuation and structure remain intact.
Use it when reducing vocabulary repetition in long articles, when matching tone for a specific audience, when preparing multiple SEO content variants, and when warming up before serious editing — sometimes a fresh vocabulary perspective helps you see structural issues.
Run with very low intensity (20%) for subtle freshening. Run with high intensity (80%) for aggressive vocabulary change. Always edit output to fix awkward word choices the algorithm couldn't avoid.
Each word is checked independently. The same word in different sentences may get different synonyms or stay unchanged based on the random roll.
Not in this UI — the thesaurus is built in. For custom dictionaries, use a desktop tool like Sublime Text with a snippet plugin.
Curated for general use. Some synonyms shift nuance — read output carefully.
