Listaki is a mobile app that helps families organize what comes in and out of their home, avoiding waste and saving money. Brazilian families waste an average of R$1,200/year on expired or forgotten food — Listaki turns that into real, effortless control.
People buy duplicates without knowing what's already in stock, food expires forgotten in the fridge, paper lists get lost and there's no real visibility of monthly grocery spend.
A unified app: real-time home inventory, automatic expiration alerts, smart shopping list, receipt scanning and monthly spending balance — all powered by AI to reduce friction.
The Challenge
Managing food and products at home is still a disorganized process. People usually rely on notes, multiple apps, or memory to track purchases and expiration dates — leading to waste, duplicate buying, and little visibility into consumption habits.
The Numbers
The problem is measurable: food waste in Brazil, family buying habits and the direct impact on the household budget. The data below shows why Listaki exists.
The Solution
Listaki was created to unify this entire journey into a single experience. Users can register purchases and create smart lists; manage home inventory in real time; receive automatic expiration alerts; track spending and consumption history; use AI to get personalized suggestions; and participate in rankings and unlock achievements through gamification.
Taki AI
Taki is the intelligent assistant built into Listaki. Based on the products available in the user's inventory, it offers contextual and personalized recommendations. Examples: "What can I make with banana, oats and milk?" "Suggest me a dinner." "What can I cook without going to the store?" The AI was designed to make the experience more useful, proactive, and human.
Design Philosophy
Listaki was built following four principles: Simplicity — fewer steps and less friction to complete tasks. Clarity — important information always visible and easy to understand. Intelligence — AI acts as an assistant, offering relevant suggestions at the right moment. Consistency — the entire experience is supported by a proprietary Design System, ensuring visual standardization and scalability.
