Tips for better results

  • Fix the facts first

    The tool keeps what is in the text, mistakes included. Check data, dates and names before you humanize.

  • Add your own experience

    No AI knows what you have lived. A real example, a number from your business or an opinion does more for a text than any rewrite.

  • Read it out loud

    If you stumble over a sentence, your reader will too. Shorten it or split it.

  • Long texts, one part at a time

    For long articles, send one section at a time: the rewrite stays more faithful and is easier to review.

  • Use it to improve, not to hide

    Schools and companies have their own rules on AI use. Use the humanizer to make text easier to read, not to hide authorship where that is not allowed.

Frequently asked questions

Is the AI humanizer really free?

Yes. There is no paid plan for this tool and no sign-up. The limits are 1,000 words per text and 12 uses every 10 minutes per connection, so the service stays up for everyone.

Will the humanized text pass AI detectors?

There is no guarantee, and be wary of anyone who promises 100%. Detectors make mistakes both ways. The humanizer reduces the most common marks of AI text, such as same-length sentences and stock phrases; what really makes a text read as human is adding your own experience and details.

Does Google penalize AI-written content?

Google says it rewards helpful, high-quality content however it is produced. What breaks its policies is using automation to publish content at scale with no value for readers. Humanizing improves readability, but the content still has to be useful.

Which languages does it support?

English, Portuguese, Spanish and most languages that AI models understand. The text comes back in the language it was written in: the tool does not translate.

Is my text stored?

Contentor does not store your text: it is sent to an AI model only to produce the answer. Even so, avoid pasting personal data, passwords or confidential information.

How is humanizing different from paraphrasing?

Paraphrasing swaps words for synonyms. Humanizing works on rhythm, structure and tone: varied sentence lengths, less jargon and a more direct voice. The meaning and the information stay the same.
