AI Paraphraser — what it does
Rewrites text without changing what it says — you choose how far it moves. Offline mode is a rule-based rewriter that runs entirely on your device using curated synonym, phrase and contraction maps, and it shows you every substitution it made. AI mode sends the text to your own LLM provider for the styles a rule engine cannot do well: creative, academic and humanize.
How to use AI Paraphraser
- Paste the text you want to rewrite — a paragraph, an email, a section of an article.
- Pick the rewrite style: standard, fluent, formal, simple, shorten, or the AI-only options creative, humanize and academic.
- Add anything that must survive untouched (product names, GST, ₹1,999) in the preserve field.
- Run it. The comparison panel shows the rewritten text, the original, the edits made, and four numbers: words, share rewritten, share still similar, and readability before/after.
- Read the result out loud before you publish it. A rule engine can make a sentence stiffer even when every word is a valid synonym.
Worked example: tightening a bloated paragraph
Input: “In order to improve the performance of the website, we need to make use of a number of tools. A lot of people think that this is very difficult, but it is actually quite easy.” With the formal style the phrase map first collapses “in order to”, “make use of” and “a lot of”, contractions are expanded, and the report lists 6 changes with a readability score before and after — so you can see it got simpler, not just different.

Frequently asked questions
- What is AI Paraphraser?
- Rewrite any text in a different style — standard, fluent, formal, simple, shortened, or creative with your own LLM provider. Offline mode rewrites on your device with curated synonym and phrase maps, and reports exactly what changed.
- Is AI Paraphraser free to use?
- Yes — AI Paraphraser is free to use, with no sign-up, no install and no account.
- Does AI Paraphraser upload or store my data?
- No — processing happens in your browser. AI requests go directly from your browser to the AI provider you connect with your own key, so your data never touches a SarvTools server.
- How does the AI in AI Paraphraser work?
- It uses a bring-your-own-key model: you connect your own provider (OpenAI, OpenRouter, Groq, Gemini or DeepSeek) in Settings, and your key stays in your browser.
- Is the offline rewriter good enough for real writing?
- For trimming bloat, removing filler and de-formalising stiff prose, yes — and it is deterministic, so you can see exactly what changed. For restructuring an argument or matching an author's voice you want AI mode.
- Will it make my text pass an AI detector?
- No tool can promise that, and we will not pretend otherwise. Rewriting changes word choice and sentence shape; detectors score statistical patterns. Use it to write better, not to evade a checker.
- Does it change my numbers or names?
- Numbers and capitalised names are protected, and anything you type into the preserve field is never touched. Always read the output before publishing — the comparison view exists for exactly that check.
