Instacart (Maplebear Inc.) is a North American online grocery delivery platform connecting customers with personal shoppers from major retailers.
Meta's Muse agent hit No. 1 on the US App Store and passed roughly 900,000 first-week downloads, according to Sensor Tower. Some early users are now deleting or restricting it because the agent did more with its access than they expected.

Amazon has blocked Meta's Muse shopping agent while Walmart, Best Buy and four other partners joined Meta's connector slate. Meta takes a small fee per Muse checkout, so the agent's retail value hinges on order counts and a rate Meta has not published.

McDonald's uses AI to price each store's menu by local willingness to pay, Reuters reports, with a Big Mac costing 21% more at one Fresno store than another. The tool's terms leave franchisees answerable for antitrust compliance on prices headquarters recommends and monitors.

DoorDash is running its AI ordering agent inside Apple's Messages app for 20,000 US pilot users on iOS, with checkout handled in the text thread. For now the channel is a bet on convenience and on DoorDash keeping its customer file, since it has released no basket figures for the pilot.

Walmart CEO John Furner pledged that Sparky, its AI assistant, will not use shopper data to raise prices as digital labels spread across 4,600 stores. The letter's named limits give assistant builders a specific test to copy, though Walmart checks its own compliance.

Almost every announcement at the hour-long keynote tied back to Meta's personal agent, including glasses from $449 and a Mac that Muse can operate while the user is away. The metaverse barely came up.

Governor Mikie Sherrill signed the Fair Price Protection Act in July, halting new electronic shelf labels for a year while the state studies them. Walmart, which promised digital tags in all 2,300 of its US stores by the end of the year, calls the law an overreaction.

The San Francisco startup records production work and expert corrections, turns them into task-specific tests, and reroutes traffic only when a cheaper candidate passes; the studies behind that are its own.
Reality
The agency says it cannot ban the practice, only the undisclosed version of it. That leaves pricing and data teams owing an answer on which customer data moved a price.

The vibe-coding startup runs about 150 agents internally at 10 to 15 per human. That ratio, not the avatars, is the number buyers will end up defending in board decks.

The Caper Cart's cameras, scale and edge compute turn a store trip into a measurable channel. The scale claims stay vague, but the ownership question does not.
