Rewrite text online with AI

Paste your text and pick a goal: paraphrase, simplify, make it formal, shorten or expand. The meaning stays, the wording changes. Free, just your email.

How to use

Paste the text

Up to 6,000 characters on the free plan: a paragraph, a whole email or a section of a paper.

Pick the goal

Paraphrase keeps the length and swaps the wording. Simplify makes it easy to read. Formal, shorten and expand do what they say.

Copy the new version

The rewritten text appears below with the paragraphs intact. Not quite right? Generate again gives you another take.

What it is for

Avoid repeating yourself

Reuse your own copy on another channel without publishing the same sentence twice: website, email, proposal, post.

Papers and articles

Paraphrase an idea in your own words so you can cite it properly instead of copying the original passage.

Hard-to-read text

Simplify a contract, a manual or a technical notice for people outside the field.

Fit the space

Shorten what does not fit (bio, ad, caption) or expand a two-line draft into a full paragraph.

Frequently asked questions

What exactly does the rewriter do?

It reads the whole text, understands the meaning and writes it again according to the goal you chose. In paraphrase mode it changes the wording and sentence structure while keeping the same content and length. In the other modes it also simplifies, formalizes, shortens or expands.

What is the difference between paraphrase and simplify?

Paraphrase swaps the wording while keeping the level of the text: it says the same thing another way. Simplify lowers the difficulty: short sentences, common words, one idea per sentence, written for someone new to the subject.

Does the meaning stay the same?

Yes. Our AI engine is instructed to keep the meaning, the facts and the paragraphs of the original. It does not invent data or add information that was not in the text, not even in expand mode, which develops the ideas already there.

How much does it shorten or expand?

Shorten returns about half the length, cutting repetition and filler without dropping any essential idea. Expand returns about double, developing the ideas with explanations and transitions. For finer control, run it more than once.

Is it free? Do I need an account?

Free: you sign in with just your email (a 6-digit code, no password) and get 3 rewrites per day, with texts up to 6,000 characters. With Rollin Ferramentas Pro there is no daily limit and texts can be up to 15,000 characters.

Does it work in Portuguese and Spanish?

Yes. The rewriter replies in the language of the text you send. Paste English, Portuguese or Spanish and the new version comes back in the same language, in a register that fits it.

Is my text stored?

No. The text is sent encrypted, used only to generate the rewrite and discarded. We keep only a record that the operation happened, to count the daily quota.

Can I use it for plagiarism or to fool detectors?

That is not what it is for. The tool is for reusing your own copy, citing in your own words and adapting the register to each audience. Rewriting text that belongs to someone else and signing it as yours is still plagiarism.
