5 sites to check if the text was written by ChatGPT

Artificial intelligence is redefining the limits of what is capable of humans and machines. With the advancement of ChatGPT and other generative AIs that can create content, it is becoming difficult to distinguish which texts were written by people and which are the product of machines. In this context, websites that function as an AI detector that helps identify texts generated by technology emerge.

We have selected five websites that can help companies and individuals identify texts written in Portuguese.

Smodin

The Smodin AI detector works well for Portuguese texts. The site is free to use, with a character limit. There are also plans that range in price from $12 to $63. Paid plans offer rewriting, summarizing, and translation services.

ZeroGPT

The ZeroGPT website does not yet offer AI detection for Brazilian Portuguese, but only for Portuguese. However, it can also work for texts written in Brazilian Portuguese. The AI ​​detector highlights the sections of the text in which the possibility of using the machine to generate the content has been identified.
