How to use

Describe the product

What it is, what it is made of, measurements, colors, what comes in the box and who it is for. You can paste the supplier spec sheet: up to 6,000 characters on the free plan.

Pick the channel, length and tone

Online store, Mercado Libre, Shopee, Amazon or Instagram change the shape of the text. Short, medium or long sets the length; persuasive, informative, premium or playful sets the voice.

Copy and fill in the blanks

The result comes in three parts: Title (up to 60 characters), Description and Highlights as a list. Wherever a measurement or detail is missing, you get a [bracket] to fill in.

Frequently asked questions

What does the generator give me?

Three parts, in plain text: "Title:", with a product title of up to 60 characters; "Description:", with 1 to 3 short paragraphs that open with the main benefit; and "Highlights:", with 4 to 6 lines, each a concrete feature or benefit. Just copy and paste into the listing or the product page.

Does the AI make up features the product does not have?

No. Our AI engine writes only from what is in your description. Wherever a measurement, material or detail is missing, it puts a [bracket] in its place for you to fill in with the right data before publishing. Always check the brackets before copying.

What changes from one channel to another?

The online store gets a full product page. Mercado Libre calls for clear, keyword-rich copy that is easy to scan. Shopee uses short lines with benefits first. Amazon gets benefit-led bullet points. Instagram becomes a lighter shopping post. Same product, different way of telling it.

How long is each option?

Short: 50 to 80 words, for Shopee, Instagram or a simple product. Medium: 100 to 160 words, the standard for marketplaces and online stores. Long: 200 to 300 words, for a technical or higher-priced product that needs more explanation. In every case the title stays within 60 characters.

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 descriptions up to 6,000 characters. With Rollin Ferramentas Pro there is no daily limit and the text can be up to 15,000 characters, enough to list a whole catalog.

What information should I put in the text box?

Everything you know about the product: what it is, material, measurements, weight, colors, voltage, what comes in the box, warranty and who it is for. You can paste the supplier spec sheet as is. The more data, the fewer brackets in the result.

What language is the description in?

The language of the page: here, English; on the Portuguese version, Portuguese; on /es, Spanish. The product spec can be in another language and the description still comes out in the language of the page, with the labels Title, Description and Highlights.

Is my text stored?

No. The description is sent encrypted, used only to generate the result and discarded. We keep only a record that the operation happened, to count the daily quota. The generated text is not saved either: copy it before leaving the page.
