The crisis that has affected journalism since the beginning of the century has led to the dismissal of thousands of journalists worldwide. To address the lack of human resources, many newspapers have turned to artificial intelligence (AI), but the introduction of non-human and poorly scrutinized systems has raised new questions related to the transparency of the journalistic process, affecting the already fragile credibility of the media. In the absence of legislation related to the use of AI in journalism, the media have been publishing recommendations to guide professionals. In this work, we analyze two pioneering documents, one from Estadão (Brazil) and another from the BBC (UK), which show how these media seek to gain consumer trust by explaining how they use artificial intelligence in newsrooms.
