The new digital platform PosoKanei has officially gone live, giving consumers the ability to compare product prices across major supermarket chains in real time, monitor price change histories and compare prices in the Greek market with the average prices of equivalent products in European Union countries.

Presenting the new digital application during a meeting at the Maximos Mansion, Prime Minister Kyriakos Mitsotakis focused on strengthening market transparency and providing citizens with more tools to tackle rising living costs. He described the platform as another meaningful step in the effort to contain the cost of living, stressing that consumers can now directly compare product prices both between the country’s major supermarket chains and with equivalent prices in European markets.

The platform was also presented at a press conference at the Ministry of Digital Governance, attended by Digital Governance Minister Dimitris Papastergiou, Development Minister Takis Theodorikakos, Despoina Tsaggari, Governor of the Independent Authority for Market Supervision and Consumer Protection, and Keyvoto co-founder and CEO Giorgos Papadimitriou.

The new service is an upgraded evolution of e-Katanalotis and is available through the website posokanei.gov.gr and mobile applications, without requiring users to create an account. In its current form, it includes nearly 8,000 products from 10 major supermarket chains, while plans call for the database to be gradually expanded to around 10,000 product codes.

Users can create shopping lists, calculate the total cost of their basket by supermarket chain, search for cheaper alternatives and monitor price developments over a two-month period. At the same time, the platform enables comparisons between prices in Greece and the average prices of equivalent products in other European countries, offering a more comprehensive picture of the market.

The following are 22 questions and answers about the new platform:

How It Differs from e-Katanalotis

The new platform introduces innovative monitoring and transparency tools, transforming simple information into genuine purchasing power for consumers.

At the same time, it is a tool that strengthens competition, as the supermarket chains themselves also monitor it, with prices being collected either through direct data provision by the retailers or through automated crawling of their online stores.

What follows is a full analysis of the structural, functional and technological differences between the older “e-Katanalotis” application and the new “PosoKanei” platform.
