Free AI Rewriter for Any TextNew Goal, Same Message
An AI rewriter writes your existing text again for a new goal: a formal report becomes a friendly update, a long email becomes three lines, a blog post becomes a LinkedIn post. Paste the text, say who it is for now, and get a version that fits.

What an AI Rewriter Does
An AI rewriter takes a text you already have and writes it again for a different purpose. Swapping words is the smallest part of it. The bigger job is changing what the text is for: the same facts told to a new reader, in a new tone, at a new length or in a new shape, such as a list, a script or a short post.
That is where a paragraph rewriter with fixed buttons runs out. It can make a text "formal" or "shorter", but it does not know that your reader is a busy manager who reads on a phone, or that the post goes on LinkedIn and must end with a question. In the chat you say that, and the rewrite follows it.
A rewrite changes who the text is for; the other tools change less. To keep the meaning and length and only refresh the wording, use the paraphrasing tool, and when a single sentence is what sounds wrong, the sentence rewriter gives you several versions of it.
A rewriter also needs something to work on. With no text yet, begin with the AI writer, which drafts from a short description, and bring the result back here when it needs a new audience.
Before and After: Four Rewrites
Examples written for this page to show what each kind of rewrite changes. Your own results will differ with your text and your instructions.
Goal given to the AI: rewrite for a team chat, friendly, same facts.
Before: "Please be advised that the office will be closed on Friday due to scheduled maintenance."
After: "Heads up: the office is closed this Friday for maintenance."
Goal given to the AI: rewrite for customers with no technical background.
Before: "The app syncs via end-to-end encrypted delta updates."
After: "Your changes are saved to all your devices, and only you can read them."
Goal given to the AI: under 20 words, keep the deadline.
Before: "I wanted to follow up on my earlier message regarding the budget figures, since we will need them before the planning meeting next Tuesday."
After: "Could you send the budget figures before Tuesday's planning meeting?"
Goal given to the AI: a social post with a hook and a question at the end.
Before: "A survey of our customers showed that most of them read our newsletter on their phones in the morning."
After: "Most of you read this newsletter on your phone in the morning. When do you read yours?"
These are illustrations, not recorded output. We wrote the lines above to show what each kind of rewrite changes. The AI will phrase your text in its own way, and a different model or a second try gives a different version. Check every fact in any rewrite AI gives you against your original before you use it.
Tell the AI These Four Things
An AI rewrite is only as good as the goal you give it. Put these four in your message and the first version is usually close.
Who reads itYour manager, a customer, a teacher, a friend, a stranger on social media. The reader decides the vocabulary and how much to explain.
The toneFormal, friendly, confident, neutral, playful. One or two words are enough.
The lengthA word count or a shape: "under 80 words", "three bullets", "one screen on a phone".
What must not changeNames, numbers, dates, links, a quote or a legal line. Listing them keeps them exactly as written.
AI Rewriter Questions
Answers to what people ask about rewriting text with AI.
Look for one that asks what the new version is for, not only which words to swap. On N33 the rewriter is a chat, free to start with GPT-5.6 Luna, Claude Haiku 4.5 and Grok 4.5, so you can describe the reader, tone and length and compare models on the same text.
Yes. GPT models rewrite text well when you say what the new version is for. On N33 you can use GPT-5.6 Luna for free, or pick Claude or Grok for a different style.
A text rewriter that uses a language model to write an existing text again: in new words, or for a new tone, audience, length or format, while keeping the facts it contains.
On N33, nothing to start: three models are free, and guests have a daily limit. A new account gets 50 energy and can claim 10 a day; larger models need an account and cost energy per message, for example Claude Sonnet 5 at 2 and Claude Opus 5 at 5.
Yes. Ask for a professional tone and name the reader, for example "rewrite this as a polite email to a client". Always read the result before sending it: AI can drop a detail or add one.
There is no single winner: each model writes in its own style, and the best one depends on your text. Send the same request to two models in the chat, GPT-5.6 Luna and Claude Haiku 4.5 for example, and keep the version you like.
