Belgian supermarket Coca-Cola prices
Grok Bot compared Coca-Cola prices across Belgian supermarket sites, then handed the browser to the author to clear a Carrefour human check.
It returned a price table and promotions, noted Aldi and Lidl gaps, and revised the best price per liter to Carrefour's 1,48 euro two-liter.
Overview
How it was set up
Grok Bot beta, using a cloud computer with a browser. The author gave a plain-language request and clicked the Cloudflare human check when Carrefour blocked it.
Worth knowing
Author would not publish the prices as fact for a business. Carrefour needed a manual human-check click.
A prompt to start from
Compare the price of a bottle of [product] across the major [country] supermarkets. Tell me the cheapest and most expensive, and flag any promotions running today.
