Paste your text below and the rephraser swaps in synonyms and reworks common phrasing to give you a fresh paraphrase — entirely in your browser, with nothing sent to a server.
This tool is a rule-based, dictionary-driven paraphraser that runs 100% client-side — there is no AI server, no account, and no data ever leaves your device. It works in three deterministic passes over your text. First, a phrase pass scans for multi-word expressions (for example in order to → to, a lot of → many, due to the fact that → because) and replaces them with shorter or alternative wordings. Second, a synonym pass walks each remaining word, looks it up in a built-in thesaurus of several hundred common words, and substitutes a synonym while preserving the original capitalization and trailing punctuation. Segments already rewritten by the phrase pass are skipped so words are never double-replaced.
The Rewrite strength slider controls how aggressive the substitution is. The formula is simple: for each candidate word the tool computes a replacement probability p = strength / 3, so Light strength changes roughly one word in three, Balanced about two in three, and Strong attempts every word that has a known synonym. A seeded pseudo-random generator drives both which words are touched and which synonym is chosen, so the rewrite is reproducible for a given input — and pressing Try another variation reseeds it to produce a different valid paraphrase from the same source. The live counters show how many words were actually swapped and the resulting rewrite rate (changed words ÷ total words), a quick proxy for how far the paraphrase has drifted from the original. Because every transformation is a transparent dictionary lookup, the output stays readable and you can always see exactly which words moved when Highlight changes is on. For best results, rephrase one or two sentences at a time and then proofread — automatic synonym swaps occasionally pick a word that does not fit your exact context.
