McDonald's unveils "Archy" AI drive-thru amid sales slump

McDonald's is positioning Archy as more than a novelty: the company says the voice system handles both English and Spanish, and claims an accuracy rate above 90% at early-test restaurants alongside positive customer feedback. That framing matters because the chain is trying to address two problems at once — slumping sales and a plunging stock — and is presenting the drive-thru AI as part of the answer.

The cautionary case sits right next door. Burger King rolled out an AI-enabled drive-thru system earlier this year and is now rethinking its strategy following customer backlash. Burger King's vice president of brand technologies, Chakri Somisetti, put the problem plainly: there are drive-offs because guests don't want to talk to a bot. For McDonald's, which serves 70 million daily customers, the scale of its own footprint is the variable Burger King's experience does not settle. Even a 90% accuracy rate would leave 7 million of those customers facing a potential error — making the rollout a customer service test as much as a technology one.

What the outcome hinges on, then, appears to be whether McDonald's can hold its accuracy claims once Archy moves beyond early-test restaurants, and whether diners accept a bot in place of a person. The Burger King reversal suggests that acceptance is not automatic, even when the underlying technology works as advertised.
