Eatoro is an AI-powered household food inventory platform that automatically transforms grocery receipts into structured household inventories.

Upload or forward your grocery receipts, and Eatoro automatically recognizes purchased products, organizes them into your household inventory, estimates expiry dates, and helps reduce food waste without manual data entry.

Built using OCR, AI-powered product extraction, and product normalization, Eatoro is designed to remove the friction from pantry management. Instead of manually adding products or scanning barcodes, users simply continue shopping as usual while their inventory stays up to date.

Today Eatoro supports Lithuanian grocery receipts from major retailers, with plans to expand to additional retailers and countries.

Our long-term vision is to build the AI-powered data layer for household food intelligence, helping people waste less food, make smarter shopping decisions, and better understand their consumption habits.

Questions & Answers

As answered by people managing Project Euler and Eatoro.lt.

What makes your product unique?

Eatoro.lt's answer:

Eatoro removes the biggest friction in pantry management: manual data entry. Instead of adding products one by one or scanning barcodes, users simply upload or forward grocery receipts. Eatoro automatically builds and maintains a household food inventory using AI, OCR, and product normalization, making food tracking effortless.

Why should a person choose your product over its competitors?

Eatoro.lt's answer:

Most pantry apps require users to manually maintain their inventory, which often leads to low long-term engagement. Eatoro automates the entire process by turning grocery receipts into a living household food inventory. It saves time, reduces food waste, and requires almost no additional effort after shopping.

How would you describe the primary audience of your product?

Eatoro.lt's answer:

Eatoro is designed for busy households and individuals who want to reduce food waste and better manage groceries without spending time manually tracking products. It's especially useful for people who shop regularly, cook at home, and want a smarter way to organize their food.

What's the story behind your product?

Eatoro.lt's answer:

Eatoro started with a simple observation: most people don't actually know what food they already have at home. Existing pantry apps solved the problem with manual product entry, but very few people were willing to maintain an inventory every day. Eatoro was created to automate that process using grocery receipts, making food inventory management almost effortless.

Which are the primary technologies used for building your product?

Eatoro.lt's answer:

Artificial Intelligence (AI) Optical Character Recognition (OCR) Product normalization Semantic matching Next.js TypeScript PostgreSQL

Who are some of the biggest customers of your product?

Eatoro.lt's answer:

Eatoro is currently in beta and focused on individual households. Current users include early adopters from Lithuania who help validate the product and provide feedback as we continue improving the platform.
