The supermarket is where a few dollars saved each week add up to real money over a year. The catch: prices change constantly, vary from one chain to another, and promotions aren't always what they claim. That's exactly where AI supermarket savings come from.
Why supermarket prices are hard to optimize by hand
- Prices differ from one chain to another, and even between stores.
- Unit price (per pound or per ounce) is the only true yardstick, yet it's rarely compared.
- Flyer 'offers' often lean on an inflated reference price.
- Coupons and online-order cashback are scattered everywhere.
What an AI supermarket assistant does for you
Compare stores in seconds
You name a product, the AI returns the prices recorded at the major chains, sorted by all-in price. No more digging through circulars.
Reason in unit price
A 'family size' pack isn't always the cheapest per pound. The AI normalizes quantities so you compare like for like.
Expose fake promotions
By keeping a price history, the AI knows whether the 'was' price matches the reality of recent weeks, or whether it was inflated for the occasion.
Your weekly cart, optimized
Beyond a single product, an AI supermarket assistant really pays off on the whole list. Pépite computes two strategies:
| Strategy | How it works | Best for |
|---|---|---|
| Split cart | Each item at its lowest price, whatever the store | People who want maximum savings |
| Single-store cart | The one store that's cheapest for the whole list | People who want a single trip |
You see the estimated savings and where they come from, item by item.
In store or online pickup?
The approach works either way: with online pickup, you order directly at the best price; in store, you arrive with the optimized list and the right coupon in hand. Better still, put your recurring products (coffee, detergent, diapers…) on price watch, and the AI lets you know when it's the right time to buy.
