GroceryTruth

A consumer browser extension and app that flags when a grocery item's shelf price has been pushed up by a recent tariff and offers substitute brands that aren't affected.

Target user

US grocery shoppers trying to stretch a tight weekly food budget

Features
  • Scan a barcode in-store and see 'price +12% in 6 weeks due to 2026 tariff on [category]'
  • Suggests unpinned alternatives (different brand, bulk pack, store brand) not caught by the same tariff
  • Weekly 'kitchen hit list' email showing top 5 tariff-inflated staples
  • Receipt-import that estimates how much of last month was tariff-driven
Why now

Tariff stories are now landing on the average American's kitchen counter - and there is no consumer tool that translates trade-policy headlines into grocery-cart savings.

Demand

Multiple tariff-translation Chrome extensions (Tariff Lens, Show Tariffs) launched in 2025 and received news coverage, indicating real consumer curiosity; Google Trends confirms >200 searches for 'tariff' with grocery prices a recurring news topic.New Chrome extensions reveal tariff impacted prices on Amazon, eBay and moreTariff Lens - Chrome Web Store

Whitespace
3/10

Direct competitors already exist: Tariff Lens and Show Tariffs do tariff price overlays on e-commerce, and The Cost Index explicitly 'tracks how international trade policies affect grocery prices' — the core value prop is already being executed, just not yet bundled with in-store brand substitution.Show Tariffs - Chrome Web StoreThe Cost Index | Economic Data & Price Tracking

Monetization
4/10

Hyperlocal grocery price-comparison market is sizable ($1.2B growing to $4.9B by 2034 per Stratistics MRC), but consumer browser extensions typically monetize poorly — Tariff Lens is free, affiliate on substitute brands is the most plausible path, and grocery shoppers are notoriously reluctant to pay subscription fees for savings tools.Hyperlocal Grocery Price Comparison Apps Market Forecasts to 2034

Longevity
4/10

Tariff regimes are politically volatile — current US tariffs could be rolled back or expanded unpredictably, which would either deflate the tool's relevance or make substitute suggestions unstable; consumer 'tariff fatigue' may also reduce urgency within 12-24 months.

Feasibility
4/10

Tariff schedules and HTS codes are public, but in-store US grocery shelf pricing lacks a clean public API — would require retailer partnerships, receipt-scan crowdsourcing, or scraping, which is far harder than Tariff Lens's Amazon/eBay overlay and adds significant product-taxonomy work for brand substitution.
