How this tool works
Be aware of what the offline mode actually does: it swaps a short list of stock words — use becomes utilize, good becomes exceptional, make sure becomes ensure — and returns your sentence otherwise untouched. Meaning, structure and rhythm are unchanged. That is word substitution, not paraphrasing, and the result label says so rather than pretending otherwise.
There is no honest way to paraphrase in a browser without a language model, so the tool does not claim to. Add a free AI key and you get three genuine rewrites — plain, formal and fluent — that restructure sentences rather than swapping vocabulary, while keeping every fact, figure and name exactly as you wrote it.
Getting a usable rewrite
- Paste whole paragraphs: a rewrite needs context. Single sentences give the model nothing to restructure around.
- Keep quotes out: anything in quotation marks should stay verbatim. Rewriting a quotation is misquoting a source.
- Read all three versions: they differ in structure, not just wording. The best sentence is often in a different version from the best paragraph.
- Check names and numbers: the instruction is to preserve them exactly, but verify before you publish.
