Hey Product Hunt! I'm Boris, founder of AITasker.co and AgencyTech.ai. I built ShelfShock because I was tired of reading headlines about "$100 oil" and "Hormuz crisis" without knowing what it actually meant for my weekly shop and cost of living, beyond what gas station price displays shout at me on every corner. The problem: commodity prices are reported in barrels, bushels, and troy ounces - units nobody uses at the supermarket. I wanted something that translates "$98/barrel Brent crude" today into "your petrol is going up 25 cents this month" for any city in the world. The approach: pull live data from commodities and cost-of-living APIs for 8,000+ cities, then enrich with current news from sources including Yahoo Finance, Guardian, MediaStack, and Google News, so the analysis references actual local developments relevant to your city - like Japan's fuel subsidies or Australia's diesel rationing - not just generic market commentary. The compare feature lets you see London vs New York side-by-side with automatic currency conversion, which has been not-so-surprisingly popular. Would love to hear which cities you check and whether the analysis matches what you're seeing at your local shops. What would make this more useful for you?
