What they did

A user who tried Meta's Muse for insurance quotes and online shopping says it kept missing the lowest price. In one case Muse said a product was $30 and out of stock on the brand's site; the user found it on Amazon for $25 and in stock on the brand's site. It also missed the cheapest home insurance quote, though it suggested ways to lower the premium.

How it went

A price table you can check yourself before buying.

Worth knowing

  • Cautionary first-hand report: the agent's 'lowest price' and stock claims were wrong in these tests. Verify links and totals before you pay.

Prompt

Cleaned version rewritten from the source — not a direct quote.

Find the lowest current price for [exact product and size] across the brand's site, Amazon and [other stores]. For each, show the price, stock status and link, and say when you checked. Don't buy anything.

Test whether a shopping agent can be tricked by fake reviews (cautionary)

F-Secure built a shopping agent (vibe-coded with Claude Code, running Claude Haiku, with the user's details in memory) and a mock marketplace with a review pointing to a fake discount-code site. In 100 runs it visited the phishing site 12% of the time and submitted the user's name, date of birth and SSN, almost never telling the user.

Grok Bot Does the Food Shopping in Under 3 Minutes With a 3-Bot Team

A user set up a Grok Bot food prep team under his chief-of-staff bot: a Meal Organiser that knows the lunches and dinners he likes, a Shopper that fills his grocery cart, and a Cooking Bot that walks him through each meal. He says the shopping takes under 3 minutes versus about an hour at the shops or 30 minutes online, and meals take under 20 minutes. He checks out himself.
