From price movement to deal discovery.
Price Error Scanner analyses retailer product data and surfaces unusually low prices with contextual confidence signals.
Collect price data
Retailer product data is ingested into our Supabase-backed product pipeline.
Compare behaviour
Current prices are compared with historical behaviour, competitor medians and sudden percentage changes.
Score anomalies
The detection engine assigns confidence scores so stronger, more unusual price movements can rise to the top.
Surface the deal
Qualified anomalies are displayed with the retailer, current price, typical price, potential saving and detection time.
You choose
Shoppers decide whether to visit the retailer. Prices and availability can change at any time, so the retailer's live page remains the final source of truth.
Affiliate funded
Some retailer links are affiliate links. If a purchase is completed, Price Error Scanner may earn a commission at no extra cost to the shopper.
