Change the tone of your text with AI

Paste your text and pick a tone: formal, casual, friendly, professional, confident, empathetic, playful or direct. The facts stay, only the way of saying them changes. Free, just your email.

How to use

Paste the text

Up to 6,000 characters on the free plan. A WhatsApp message, an email, a notice, a post, a reply to a customer.

Pick the tone

Eight options: formal, casual, friendly, professional, confident, empathetic, playful and direct. Each one changes wording and rhythm, never the facts.

Copy the new version

The text in the new tone appears below with the paragraphs in place. Try two tones and keep the one that fits the reader.

What it is for

Payment reminders and hard notices

Turn a blunt reminder into a firm but empathetic message, or the other way round, without losing the information.

From WhatsApp to email

The casual message you would send a colleague becomes a professional email to the client.

Social media

A formal company announcement becomes a friendly or playful post with the same content.

Replying to a complaint

Rewrite the reply in an empathetic, confident tone before sending it to an unhappy customer.

Frequently asked questions

What changes when I switch the tone?

The words, the expressions and the rhythm of the sentences. Our AI engine is instructed to keep the meaning, the facts and the paragraphs and change only the way of saying them. Names, dates, amounts and conditions stay exactly as in the original.

What is the difference between formal and professional?

Formal is respectful and distant, with ceremonious address, good for institutions, contracts and a first contact with someone you do not know. Professional is polished and direct, the tone of a work email between people who already know each other.

When should I use empathetic and when confident?

Empathetic acknowledges what the other person feels before getting to the point: a reply to a complaint, a delay notice, bad news. Confident states things plainly without hedging or apologizing: a proposal, a negotiation, a results update. You can combine them: run one tone, then the other.

Can the playful tone come out inappropriate?

It uses light humor and relaxed language, with no offensive jokes. Even so, read it before publishing: humor depends on the audience, and what works in a post may not work in a payment reminder.

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 generations 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 text comes out in the language it was sent in, with the tone markers of that language (formal in Portuguese is not formal in English). Handy for writing to clients abroad.

How is it different from improve text?

Improve text works on writing quality (clarity, strength, engagement) without switching the register. Change tone switches the register on purpose: the same content said another way, for another audience. For a weak text in the wrong tone, use both, in that order.

Is my text stored?

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