DoorDash is testing a new AI assistant that allows customers to order food directly through Apple's Messages app. This AI can access a customer's account to suggest or even complete orders based on past purchases and preferences. The service, an extension of the existing "Ask DoorDash," also offers features like viewing food photos and receiving recipe ideas based on fridge contents. U.S. iOS users can join the waitlist via doordash.com/text, with Android support expected later.
