ChatGPT, the internet-famous AI text generator, has taken on a new form. Once a website you could visit, it is now a service that you can integrate into software of all kinds, from spreadsheet programs to delivery apps to magazine websites such as this one. Snapchat added ChatGPT to its chat service (it suggested that users might type “Can you write me a haiku about my cheese-obsessed friend Lukas?”), and Instacart plans to add a recipe robot. Many more will follow.
