What I Paid – Crowdsourced real prices from receipt photos worldwide
The live feed of price swings and the receipt-upload hook are the product's clearest selling points — it's built around a concrete, shareable action (scan a receipt, surface a price delta). The dataset shown looks small and very Tesco-heavy, so the real value depends on scaling contributors and doing serious OCR/normalization and deduplication. If they tighten product matching and add credibility signals (uploader reputation, timestamped receipts, image->data confidence) this could move from handy to indispensable for local shoppers.
