Meu Mirai is a household finance service that helps people track spending, manage budgets, and work toward savings goals through WhatsApp. Users can message everyday expenses in their own words, and Mirai records each transaction, assigns a category, and reports how much remains in the monthly limit. It can also provide weekly spending guidance, adjust future weekly allowances when spending changes, and send alerts as a category approaches its limit.

Members can ask whether a planned purchase fits their budget, with responses informed by their spending, limits, and goals. For longer-term planning, users set a savings target and deadline and track progress toward it. Each person can record expenses from their own WhatsApp account, while household members can share budgets and goals.

A companion app for phones and computers presents spending, limits, reports, and analyses in a clear format. Mirai offers Individual, Couple, and Family subscriptions, with the latter supporting up to five people. A seven-day free trial is available, and subscriptions can be cancelled through the app
