One in four people now search for information and everyday questions on ChatGPT rather than on Google. Thirty percent of users trust chat responses more than search engines. This percentage rises even higher among Generation Z. Many users use ChatGPT to create summaries, translations, letters, and presentations. However, if these users intend to write in normative Catalan, they will have to be careful. The Institute of Catalan Studies (IEC) warns that artificial intelligence does not take all registers into account and, for example, does not distinguish normative Catalan from that which is not. It also includes incorrect references that induce false credibility.
