There's been a lot of chatter around artificial intelligence lately, particularly after OpenAI debuted its revolutionary ChatGPT service that Microsoft is now looking to integrate into Office 365 and Bing search. Meanwhile, Google has been a self-professed "AI-first" company since announcing a shift in focus at I/O 2017, and more recently, it unveiled a new AI-powered chatbot called Bard. But in a sea of buzzwords and initialisms, it can be hard to wrap your head around what these new tools do.
