How it works

From shopping list to savings in seconds

01

Type your list

Write in natural Finnish or English. "2 litraa maitoa, Oltermanni, banaanit" works perfectly.

02

AI matches products

Smart matching across all three chains, including store brands like Pirkka, Rainbow, and Lidl own.

03

Compare prices

See every item priced at Prisma, K-Citymarket, and Lidl. Side by side, no guesswork.

04

Get your split

Choose max 1, 2, or 3 stores. The optimizer builds your cheapest possible cart.

The gap

Finland is the only Nordic country without grocery price transparency

Sweden has Matpriskollen with 300,000 users. Norway has Kassalapp. Finnish consumers still compare prices by walking between stores or reading weekly flyers. In 2026, that's absurd.

S-Group + K-Group = 82% market share
A duopoly where consumers have no independent price data. Each chain's app only shows their own prices.
Finns already multi-store shop
Prisma for the main haul, Lidl for cheap basics, K-Citymarket for weekly meat deals. The behavior exists. The tool doesn't.
Weekly tarjous cycles
Prices shift every week. What's cheapest at Prisma today might be cheaper at K-City next Tuesday. Keeping track manually is impossible.
AI understands Finnish groceries
Natural language parsing handles "2 litraa kevytmaitoa" and knows Pirkka is K-Group's brand, Rainbow is S-Group's, and Milbona is Lidl's.

The price of your groceries shouldn't depend on which door you walk through

Ostoskori AI is building Finland's first independent grocery price database. Every product, every store, every week. Transparent pricing for 5.5 million Finnish consumers who deserve to know where their money goes furthest.
