SAN FRANCISCO (AP) — If you use Facebook, WhatsApp or Instagram, you've probably noticed a new character pop up answering search queries or eagerly offering tidbits of information in your feeds, with varying degrees of accuracy. It's Meta AI, and it's here to help, at least according to Meta Platforms' CEO Mark Zuckerberg, who calls it “the most intelligent AI assistant that you can freely use.” The chatbot can recommend local restaurants, offer more information on something you see in a Facebook post, search for airline flights or generate images in the blink of an eye. If you're chatting with friends to plan a night out, you can invite it into your group conversation by typing @MetaAI, then ask it to recommend, say, cocktail bars.
