Frequently asked questions

Does the corrector change the meaning of my text?

No. In "Errors only" mode it fixes spelling, grammar, punctuation and agreement and leaves the sentences as they are. In "Errors and flow" it also lightly rewrites confusing sentences, always preserving the meaning and the paragraphs.

Does it handle British and American English?

Yes. It respects the variant you are using and fixes spelling, agreement, punctuation and common typos. It also corrects Portuguese and Spanish, replying in the language of the text.

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 corrections 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.

What is the maximum text length?

6,000 characters at a time on the free plan, about a page and a half. 15,000 with Pro. For a long document, paste one section at a time: the correction gets more precise.

Is my text stored?

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

Does it fix commas and apostrophes?

Yes. Punctuation (commas, semicolons, colons), apostrophes, hyphens, capitalization, subject-verb agreement, prepositions and the most common typos.

How is it different from the checker in Word or Google Docs?

Traditional checkers flag word by word. This one reads the whole sentence, understands the context and returns the finished text, including agreement and badly built sentences that the red underline misses.

Can I use it to proofread text written by another AI?

Yes. The corrector treats it like any other text: it fixes errors and, in flow mode, makes it read more naturally. It does not "humanize" or try to fool detectors; it only corrects.
