Guides
Paste a sentence or paragraph and get an AI-reworded version — same meaning, different words. Useful for finding another way to say something, freshening up a line that reads too close to a source, or just getting unstuck on a sentence.
How to use it
- Paste the text you want to paraphrase (10 to 5,000 characters — a sentence or a paragraph).
- Choose a paraphrase style.
- Click Paraphrase.
- Check the "What changed" preview to see exactly which words were swapped, added, or removed.
Paraphrase styles
- Standard — natural word swaps and restructured sentences, same tone as the original.
- Fluency — smoother, more polished phrasing without changing the register — good for cleaning up awkward or non-native phrasing.
- Formal — more professional wording and sentence structure.
- Academic — precise, scholarly wording and impersonal sentence structure.
- Simple — short sentences and plain, everyday words.
- Casual — relaxed, conversational phrasing.
- Creative — more varied sentence structure and word choice, while staying strictly factual.
- Shorten — condenses the text while keeping every key point.
- Expand — elaborates with additional detail and clarifying phrasing.
Seeing what changed
The "What changed" preview highlights the paraphrase word-by-word against your original — removed words struck through, added words underlined — so you can spot exactly how much the wording actually moved instead of eyeballing two blocks of text side by side.
Tips
- The paraphrase covers only what's actually in the text you pasted — it doesn't add outside facts or its own opinion.
- For a whole article or blog post rather than a single sentence/paragraph, use Article Rewriter instead — it supports up to 20,000 characters and can lock specific keywords so they survive the rewrite unchanged.
- For a result you can share or embed without regenerating it, copy the output text — like every AI-generated tool on this site, the result isn't reproducible from a shared link (it's non-deterministic, so a link would just spend credits regenerating a different answer).
Is my text stored anywhere?
Your pasted text is sent to an AI provider to generate the paraphrase, then discarded — it isn't logged, stored, or used to train anything. See the third-party data badge above the tool for details.
Will this help avoid a plagiarism/duplicate-content flag?
A paraphrase changes the wording, but a plagiarism checker or search engine evaluates more than exact phrasing — copied structure and thin content can still be flagged even reworded. Use this to find a different way to say something, not as a substitute for writing something original.
