Frequently asked questions

What does "improve" mean here?

It depends on the focus. Clarity: cut filler, shorten long sentences, swap vague words for precise ones. Persuasion: strong opening, concrete benefits, clear call to action. Professional: precise vocabulary, consistent tone, no slang or redundancy. Engagement: a hook in the first line, rhythm and a closing that invites.

Does it change what I meant?

No. Our AI engine is instructed to keep the meaning, the voice and the paragraphs of the original. It improves the form: sentence order, word choice, rhythm. The content and the arguments remain yours.

How is it different from the text corrector?

The corrector fixes spelling, grammar and punctuation and stops there. Improve text starts from text that is already correct (or fixes errors along the way) and works on writing quality: clarity, strength, tone. For a text with many errors, run the corrector first.

Can it make my text sound more professional?

Yes, that is the "Professional tone" focus: precise vocabulary, no slang, no repetition, a consistent tone from start to finish. To change the register more radically (from formal to playful, say), use the change-tone tool.

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 improvements 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.

In persuasion mode, can it exaggerate or make things up?

The instruction is explicit: no exaggeration and no invented claims. It takes the benefits already in your text and presents them better. If information is missing, it does not create it; you fill it in.

Does it work in Portuguese and Spanish?

Yes. The improved text comes out in the language of the text you send, following the conventions of that language. Handy for anyone writing to clients abroad.

Is my text stored?

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