Use case overview
Grok Bot compared a bottle of Coca-Cola across Belgian supermarkets, named cheapest and priciest and flagged promotions, handing the browser to the user at a Carrefour captcha.
Reported experience
What they did
Peter van Hees asked Grok Bot in plain language to compare Coca-Cola prices at the major Belgian supermarkets, without naming shops or sizes. The bot worked from the official store sites rather than comparison blogs. Carrefour blocked it with a Cloudflare check, so the bot asked him to click the human check in the shared browser. He did, and it carried on.
How it went
It reported 1.5L prices (Colruyt and Delhaize 2,38 euro, Albert Heijn 2,39), noted that Aldi and Lidl lacked a comparable bottle, and found promotions. Once Carrefour opened, it revised its ranking: Carrefour's 2L at 1,48 per liter was the best. The author says the prices shouldn't be treated as publishable fact.
Worth knowing
Grok Bot has no standalone plan. The author's top-tier subscription costs 200 euros a month, and the bots share one computer's logins, so xAI says not to treat them as separate security boundaries.
Example prompts
Compare the price of [product, brand and size] across [country] supermarkets such as [store 1, store 2, store 3]. Tell me which store is cheapest and which is priciest, and flag any current promotions. If a captcha or login blocks you, hand the browser back to me, and stop once you've given me a short comparison list.
