Tips on better writing, how AI paraphrasing works, and answers to every question you might have.
Most online paraphrasers send your text to a remote server. Ours doesn't. Discover how Transformers.js and ONNX Runtime let a full neural network run directly inside your browser tab — completely offline, completely private, with zero data ever leaving your device.
Standard, Fluency, Formal, Casual, Creative, Shorten, Expand, Academic, Simplify — each mode has a sweet spot. Here's exactly when to use each one.
AI writing tools are everywhere — but are they allowed? We break down academic integrity policies, when paraphrasing is fair use, and how to use AI ethically as a student.
Pasting an entire essay at once. Ignoring word highlights. Skipping the strength setting. These common mistakes kill your results — here's how to avoid them.
Draft → Paraphrase → Expand → Polish. This four-step workflow lets creators produce 3× more content without sacrificing quality. Includes real before/after examples.
Your writing reveals more about you than you think. Medical notes, legal drafts, business plans — most AI tools store them. Here's why in-browser AI is the only truly private option.
Duplicate content tanks SEO. But rewriting by hand is slow. Learn the exact technique to use AI paraphrasing to refresh old content and keep Google happy.
Creative mode doesn't just rephrase — it reimagines. Learn how to use temperature, style prompts, and the re-paraphrase loop to discover writing styles you didn't know you had.
Yes — completely free, forever. There are no hidden paywalls, no sign-up, no credit card, and no usage limits. The AI model runs entirely in your browser using Transformers.js, so there are no server costs for us to pass on to you. Just open the page and start paraphrasing.
Never. Your text never leaves your device. The AI model (LaMini-Flan-T5) is downloaded to your browser's cache on first use and runs 100% locally using WebAssembly and ONNX Runtime. We don't have access to what you type — not even anonymized analytics on your text content.
On your first paraphrase, the browser downloads the AI model (~300 MB) from a CDN. This is a one-time download — after that, the model is cached by your browser and all future visits are near-instant. Think of it like installing an app: slow once, fast forever. You can track the download progress in the loading bar.
Each mode rewrites your text with a different goal: Standard — general clear rewrite. Fluency — smoother natural flow. Formal — professional/business tone. Casual — friendly conversational feel. Creative — vivid imaginative language. Shorten — cuts to the essential points. Expand — adds detail and context. Academic — scholarly, citation-ready style. Simplify — plain language for any audience. Choose the mode that matches your intended audience and purpose.
Strength controls how much the AI changes your text. Light keeps most of your original words and only adjusts phrasing slightly — great for polishing already good writing. Medium is the default balanced rewrite. Heavy pushes the AI to use very different vocabulary and sentence structure — ideal when you need to avoid similarity to the original, such as for repurposing content across platforms.
Every word in the output that is different from your original is highlighted with a purple underline. This gives you instant visual feedback on how much the AI changed. The "Changed %" stat in the stats bar shows the percentage of words that were swapped. If the highlight density feels too high or too low, switch strength levels and re-paraphrase.
Yes — the input is currently capped at 2,000 characters per paraphrase. This is to keep in-browser processing fast and responsive. For longer documents, we recommend splitting your text into paragraphs and paraphrasing each section individually. The counter in the top-right of the input panel shows how close you are to the limit.
The underlying model (LaMini-Flan-T5) was primarily trained on English text, so it works best with English input. It may produce partial results for other Latin-script languages, but accuracy and fluency will be significantly lower. We are exploring multilingual model options for future updates.
The ↩ Re-paraphrase button moves the output back into the input box so you can paraphrase it again. This "loop" technique is useful when you want progressively more rephrased text, or when you want to apply a second mode on top of the first — for example, first Shorten then Formalize the shortened version.
Yes! Once the model is cached in your browser, the tool works completely offline — no internet connection required. The page itself still needs to load (unless you've saved it locally), but all AI processing happens on your device. This makes it ideal for working in places with limited connectivity.
This tool is designed for legitimate writing improvement — not academic fraud or deception. Paraphrasing AI-generated text with another AI tool does not reliably "trick" AI detectors, which have become sophisticated at detecting patterns beyond word choice. Use this tool to improve clarity, adapt tone, and rephrase your own ideas more effectively — not to misrepresent the source of content.
The tool works best on Chrome and Edge (latest versions), which have the most optimised WebAssembly support. Firefox works but may be slower. Safari on macOS 14+ should work. Mobile browsers (Chrome on Android, Safari on iOS) can run the model but performance will be slower due to memory constraints. We recommend a desktop browser for the best experience.
